Assembly Instructions
1. Remove all parts from shipping carton and
check the assembly page to make sure all parts are
present.
readjust clevis/lower rod length with the sping clip
buttons so that the search coil can be held near the
floor without requiring stooping over.
2. There are rubber washers between clevis/lower
rod and loop ears. Use only nonmetallic washers,
fiber bolt, and thumbnut to secure loop/search
coil to clevis/lower rod.
7. Remove the protective paper from the two black
elbow cup foam pads. Carefully align pads on the
inside of the elbow cup, one on each side of the
center rod, and press firmly into place.
3. Unlock "S" rod camlock and insert clevis/
lower rod into curved "S" rod so that stainless
steel spring clip buttons line up and lock into one
of the adjustment holes in the curved "S" rod.
Turn camlock to secure. The second or third
adjustment holes are suitable for average size
adults. Individuals 6' or taller should use the fully
extended position. Individuals well over 6' tall
should purchase the optional Tall Man Rod.
8. Adjust the elbow cup strap so that it is loose
enough for you to slide your arm in and out without loosening each time you want to set the detector down. The elbow cup strap provides extra
leverage and control. However, some prefer not to
use it.
4. Unravel loop cable and wind the cable around
the clevis and rod assembly, first revolution over
the top of the rod. Wind cable all the way to the
top of the curved "S" rod, about five revolutions.
Use the black cable retainers, one near the loop,
and one near the top of the curved "S" rod, to hold
the loop cable in place.
5. Unlock control box rod camlock and insert
curved "S" rod so that stainless steel spring clip
buttons line up and lock into the rod on top of the
control box. The "S" rod is designed to curve up
toward the display. However, those who prefer to
sweep the loop close to their feet may desire to
assemble the "S" rod to curve down toward the
ground. Turn camlock to secure. Plug loop connector into control box, screw lock ring to secure.
9. Install battery as described in the next section,
decal facing down, with plastic tab and steel contacts
facing toward inside of battery compartment.
10. It should be noted at this point that the detector
may not work as expected indoors due to the high
degree of metals used in modern construction. It is
best to tune and practice out-of-doors to ensure
stable, predictable results. Additionally, freshlyburied targets will not produce the normal depth
and discrimination results of targets that have been
naturally lost and settled in the ground. Due to the
abnormality caused by digging a hole in the ground
matrix, and the sophistication of the ground rejection circuitry, it may take a number of years for
freshly-buried targets to respond at true depths and
discrimination accuracy. The best way to determine true detection depth is in real search conditions.
6. Grip the instrument by the handle, with your arm in
the elbow cup with strap secure, and sweep the loop/
search coil over the floor. If the instrument fit feels
uncomfortable, adjust the elbow cup by removing
and repositioning the bolt/thumbnut and installing
in one of the optional positions. If necessary,

A rechargeable battery (green decal) is provided
with your instrument. This battery can be recharged
hundreds of times as long as the battery hasn't been
stored for extended periods of time or overcharged.
Full charge can be achieved anytime during the
discharge cycle. When using the QUICK charger
setting use the Charging Hours chart on the following page for charge time. A full charge will last ten
to fifteen hours of normal use.
Battery life will vary with temperature, the number
of targets found, and the exact settings used. Six
hours is not unusual for extreme high performance
settings, backlight use, or for batteries that have
experienced extensive use.

Chapter 2 XLT® Batteries
Battery Life & Memory
Volatile memory temporarily holds any program
changes or settings not yet saved in a Custom
Program. Short-term or volatile memory is retained
so long as a good battery remains in the detector.
To recover volatile memory immediately squeeze
and release the TRIGGER once the detector is
turned ON. If the battery is removed all volatile
memory is lost. Long-term memory (programs
saved in Custom Programs) is automatically saved
for up to ten years regardless of whether a battery is
in the detector or not.
Use of maximum backlight may reduce battery life
by up to 50%, depending on battery type.
Rechargeable batteries gradually deteriorate. As
they age they do not provide the life-per-charge
they did when new. This is expected, and not
grounds for replacement under warranty. Additionally, a damaged initial cell, which is caused by
over-charging with the QUICK option, is not
replaced under warranty. Only cell failure through
normal use, or a defect due to a problem with a
White's warranted XLT® charger, is covered.
When using fresh batteries, the voltage will initially
check somewhere in the 10 to 14 volt area. Unlike
standard batteries, the rechargeable battery voltage
will quickly drop to between 9 and 10 volts and
plateau there for most of its life. Once the rechargeable battery voltage drops below this plateau, it will
quickly drop below a usable voltage level (eight
volts) and thus require a recharge. Low Battery will
automatically appear on the display when the
battery reaches eight volts.
Like a personal computer, there are times (such as
low battery conditions) when the microprocessor of
a metal detector becomes out of sequence with the
rest of the circuitry. This is often noted by peculiarities in the non-discrimination or pinpointing
(TRIGGER squeezed) modes. Symptoms may be
blaring or silent non-discriminate or pinpoint
modes, depth indication inaccuracies or general
abnormal operation. To correct such difficulties "reboot" by:
1. Install a good battery.
2. Turn ON wait for MAIN MENU to appear.
3. Open battery door and remove battery while
detector is still ON.
4. Wait one minute, re-install battery, turn
detector ON, and check for proper function.

Chapter 3 XLT® Quick Start
Search Fundamentals
The loop/search coil must be in motion (sweeping from side-to-side) for this instrument to
respond to metal. Practice a smooth sweep of the
loop from side-to-side keeping the loop close to the
ground throughout the swing. Each pass of the
loop should take approximately two seconds
from right to left, two seconds to return from left
to right.
Walk forward slowly. Take small steps no greater
than half normal strides. Make sure each pass of the
loop overlaps the last by at least half the length of
the loop. Do not lift the loop at the end of each
swing. Keep it close to the ground at all times.
To become comfortable with sweeping the loop
takes some practice. Try to loosen up and find a
comfortable grip on the handle. Premature fatigue
may result from gripping the handle too tightly,
improperly adjusted rod or elbow support, and
limited body movement. Hold the handle loosely.
Adjust the rod and elbow support for comfort and
keep the elbow strap loose. Use your arm, shoulder
and even your back a little to allow a smooth even
sweep of the loop.
Now that you're sweeping the loop smoothly over the
ground, you will notice that the detector starts making
sounds (beeps). Not all sounds are good targets;
some trash targets also make the detector beep.
As the loop is swept over the ground, ignore the
display and concentrate on the sounds the detector
makes.
As the loop is passed over metal that is likely trash,
the sound will be inconsistent. Trash targets typically produce a shorter, sputter-type sound, that is
often broken or double in nature. Place a steel-pop
bottlecap on the ground. Pass the loop over it
several times to become familiar with this sound at
different loop sweep speeds. Note that an aluminum
twist-off bottlecap cannot be used as it is a different type of target. Also note that very old rusty
bottle caps may start reading as quarters due to the
elimination of the iron alloy through deterioration.
Once familiar with the sound typical bottle caps
produce, an operator may pass over such targets and
continue searching without consulting the display
information, saving more time for evaluating
possible good targets.
As the loop passes over metal that is likely a good
target, a more consistent and smooth sound will be
heard. A good target typically produces a longer,
more solid sound. Place a quarter on the ground and
sweep the loop over it several times to become
familiar with the sound of a good target.
Why Air/Ground Balance?
When the display prompts you to, AIR BALANCE by
holding the loop at waist level and press ENTER. The
XLT®'s circuits are being prepared for ground balancing by measuring temperature and other variables that
affect electronic circuits. The XLT® "beeps" and you
lower the search coil to the distance above the ground
that you will be searching. Press ENTER to have the
XLT® "cancel/track out" or GROUND BALANCE
the ground mineralization. The XLT® then automatically "tracks out" the varying mineralization as you
continue to search.

1. V.D.I. Visual Discrimination Indication
("target reference number")
In the upper left hand-side of the display there is a
V.D.I. number that corresponds to the V.D.I.
SCALE painted on the top right-hand side of the
control box. It also corresponds to the Discriminate
Edit feature allowing you to reject or accept targets
based on their V.D.I. reference number. There are
"+" numbers for non-ferrous (not of iron) targets,
and "-" numbers for ferrous (iron) targets. Rejected
V.D.I. numbers may not appear if the VISUAL
DISCRIMINATION feature is ON. Reasonably
consistent V.D.I. reference numbers (± five digits),
in a desirable area of the chart is a vote for digging
the target.
2. Possible Target Identities ("Probable or most
likely Target")
To the right of the V.D.I. number, possible target
identities will be represented graphically. These
graphics are called ICONS. A fairly consistent
indication of a desirable target is another vote to dig
the target. One or two possible target icons may
appear. There is significance to which icon appears
first. The first target to appear is always the most
likely, the second is another possibility slightly less
likely than the first.
3. SignaGraph™
The SignaGraph™ at the bottom of the display
provides a final vote as to whether or not the target
should be dug.
10
A. Sweep the loop over the target several times and
look at the SignaGraph™. The SignaGraph™
automatically clears itself (FADE RATE) so that it
doesn't fill the screen with information from past
loop sweeps. An operator has limited time to look
at the SignaGraph™. If you want to look at the
information again, sweep the loop over the target
several more times. The fading of the
SignaGraph™ information can be slowed or
speeded (FADE RATE) to operator preference.
This is completed in the PRO OPTIONS under
DISPLAY. Automatic AVERAGING and/or ACCUMULATING of SignaGraph™ information is
also available (See PRO OPTIONS).
B. Valuable targets will show up on the positive
side of the graph. The positive area of the chart is
the section located to the right of the zero.
C. Look for consistency. In ideal conditions, coins
and jewelry produce one or two bars to the right of
zero. Trash produces several bars, sometimes on
both sides of zero.
D. In less than ideal conditions, coins may produce
a wider pattern of bars. Most trash targets produce a
recognizably different pattern than valuable targets.
E. One of the most visual benefits of the
SignaGraph™ is the ability to show a smear pattern
on iron targets that often fool the other methods of
identification. An iron target will likely show
definite bars on both the negative and positive sides
of the SignaGraph™, often smearing all the way
across the entire chart. Valuable targets should not
produce such obviously wide patterns. In very bad
ground conditions, a good target may have a few
small bar segments in the negative area due to
mineralization. However, the pattern will show
mostly positive bars, in a fairly narrow tall group.

Advanced Pinpointing Techniques
1. Targets that are near the surface, because
they give a wider response, are harder to
pinpoint than deep targets. If the trigger is held
and the loop swept over the area, you may note
a shallow depth indication. Lifting the loop
slightly above the ground, releasing and resqueezing the TRIGGER and again "X" ing the
target will aid pinpointing.
2. In the Basic Adjustments, DC Sensitivity
(non-motion) directly controls the pinpointing
mode. Lower DC Sensitivity settings pinpoint
shallow targets better.
3. In the PRO OPTIONS under AUDIO, V.C.O.
(Voltage Controlled Oscillator) significantly aids
pinpointing.
4. The depth reading has two indication bars.
The top bar shows the current distance from
the target, and the bottom bar shows a memory
of the strongest reading. These two bars will be
even with each other when the loop is directly
over the center of the target.
12
Once the decision has been made to dig, move the
loop off to one side of the target area, squeeze and
hold the TRIGGER on the handle, and "X" the loop
over the spot where you believe the target to be.
Note that the TRIGGER also has a locked forward
position that accomplishes the same thing as
squeezing and holding it.
While the TRIGGER is being held, the loop doesn't
need to be moving to detect the target. The loop
may be moved slowly over the area. The display
will indicate depth in inches and will also show the
strongest reading to aid in pinpointing exactly
where to dig. The shallowest reading on the depth
display, the loudest sound coming from the speaker,
and the two bars lining up with each other, indicate
the center of the target. Don't forget to "X" the
target as pinpointing cannot be accurate unless the
target is swept from at least two different directions.
Once pinpointing is complete, release the TRIGGER, or return it to the center position.
Pinpointing takes practice. The standard loop
provided with the Spectrum® is a high-powered, 9.5
inch design. This loop's strongest traits are in the
detection depth and ground coverage areas. If
pinpointing becomes difficult or critical, an optional
smaller loop is suggested. The smaller loops have
advantages in high trash areas and pinpointing, but
will not detect as deep as the standard 9.5 inch size.
Chapter 3 XLT® Quick Start
Ready to Dig
Factory Preset Programs
Permission - Prior to searching and digging you
must have permission to search private property,
from the owner or caretaker.
Reached from the MAIN MENU, the factory
PRESET PROGRAMS give a quick start for:
Laws - Know the laws that apply to the area you
are going to search. Laws vary a great deal with the
City, County, State, and Country, regarding the use
of metal detectors. Be respectful of private property, public property, and the laws which govern
the use of metal detectors.
Tools - Care must be taken to dig in a way that is
friendly to the landscape. Tools and methods vary a
great deal with the area, season, and types of target
you are recovering. Check with your dealer for
recommended tools and methods for your area.
Trash - When searching, remove all trash you
come across. This not only makes your future
searches of the area more productive; it promotes
the hobby of metal detecting.
Get Involved - Your dealer knows of metal detecting clubs and organizations which promote and
protect the hobby. A club is a great way to not only
learn good detecting habits, but to gain permission
to search areas as a group as well as have organized
competition hunts.
Coins: general purpose settings, discriminates
(rejects) most common junk items like nails, foil,
pull tabs, and hot rocks; and responds to most coins
and large jewelry. Use in lawns, parks, and playgrounds where lots of trash rejection is desired.
Coin & Jewelry: less discrimination (less trash
rejection), desirable because of the high degree of
variance found in jewelry alloys. More digging
required. Good program for lawns, parks, and
playgrounds. Use screen more than sound.
Jewelry & Beach: similar to Coin & Jewelry, but
Pro Options are changed for salt water.
Relic: even less discrimination than Coin & Jewelry
or Jewelry & Beach, all types of metals except
small iron items like nails, and some stainless steel.
Brass, lead, aluminum, as well as copper, silver,
and gold all respond solidly. Ferrous (iron), such as
large nails, weapons, and cannon ball fragments
will also respond . Suitable for all significant targets
and separate ferrous/non-ferrous by display indications.
Prospecting: NO AUDIO DISCRIMINATION. All
metals respond with beep. But V.D.I. numbers
show only for metals that could be gold. Dig only
V.D.I. number (possibility gold) targets and avoid
iron. Targets which cause an audio response, without causing a V.D.I. number to appear on the
display, are not likely to be gold nuggets. Although
high-frequency gold-shooting detectors will respond better, this mode will offer good results for
the occasional nugget hunter by responding to
nuggets in the nine-grain and heavier category.

Discrimination Channel - When the loop is in
motion, targets accepted by the discriminate
program will produce a high-pitched beep. Targets
rejected by the discriminate program will produce
a lower pitched beep. High-pitched or low-pitched
beeps are directly determined by the discrimination settings. An operator can select discriminate settings through the selection of an entire
Program or by adjusting the accept and reject
V.D.I. numbers in the Pro Options under
Discrimination (EDIT).
All Metal Channel -When the loop is not in
motion, or moved slowly, all types of targets will
produce the same low-pitch beep. All-metal
channel will by nature detect deeper than the
discrimination channel. Deeper targets will
produce a lower volume sound when the loop is
moved slowly over the area.

Used to select the sensitivity (degree that the detector
is responsive to signals) while the detector is being
used in non-discriminate modes. These are modes that
do not require movement of the loop to respond. D.C.
SENSITIVITY fine tunes stability and pinpointing.
Select D.C. SENSITIVITY with the ARROW
controls, and press ENTER. Use ARROW controls to
select the desired D.C. SENSITIVITY level shown by
the number on the right. Press ENTER. D.C.
SENSITIVITY levels should be selected carefully to
allow smooth, stable and predictable operation while

improving visibility.
BACKLIGHT
0
MIN
MAX
Tip - Use only when
needed, and only as bright
as needed, for acceptable
display visibility. Backlight
use will decrease battery
life. The brighter the level,
the higher the battery
usage.
CAUTION
If the instrument is turned ON and the
EMERGENCY BACKLIGHT sequence is
used, the BACKLIGHT will stay ON only
while you stay in that program. Pressing
MENU and selecting another program will
turn BACKLIGHT OFF, if BACKLIGHT
is not also ON in that particular program.
If in the dark at the time the instrument is
turned ON, you may need to squeeze and
release the TRIGGER and then use the
EMERGENCY BACKLIGHT sequence.
You can then find the program you desire,
press ENTER, press ENTER for Air
Balance, and press ENTER for Ground
Balance. Use the EMERGENCY
BACKLIGHT ON sequence a second time
if the BACKLIGHT fades in that program.
Unlike past Spectrum® instruments, the
Spectrum® XLT® BACKLIGHT is no
different than any of the other
adjustments. It can be saved in the custom
programs or short term volatile memory.
However, factory preset programs use the
OFF (0) setting as a default (standard
setting).
Select BACKLIGHT with the ARROW controls
and press ENTER. Use the ARROW controls to
select the desired BACKLIGHT level. The
BACKLIGHT level will be visible on the display.
The current level is shown on the right side of the
display. The graphic control knob shows the
relationship of the current setting to minimum and
maximum levels. Minimum is 0 (no light). The
maximum backlight setting will reduce battery life
by as much as 50% depending on the type of
batteries and how long it is used. Lower
BACKLIGHT settings will have significantly less
drain on battery life.
When the detector is first turned on, it is normal
for the backlight to be on during the opening
display and BATTERY CHECK. If the
BACKLIGHT is off, it will fade when the MAIN
MENU display appears. If the BACKLIGHT is
ON, it will continue until turned off manually or a
different program is selected. BACKLIGHT can
be saved as part of a custom program, for example
a NIGHT HUNT program.
When Backlight is ON and the TRIGGER is
squeezed and released to begin searching,
"BACKLIGHT ON" will appear continually on
the display to warn you of the extra battery duty.
EMERGENCY BACKLIGHT - If in the dark
you cannot see the display to turn the
BACKLIGHT on, holding the TRIGGER and
pressing MENU will bring up the BACKLIGHT
adjustment screen. Release the TRIGGER and
press ARROW up to select a level you can see the
display. Squeeze and release the TRIGGER to

become slower at responding. Settings toward MAX
(higher numbers) speeds
the display and improves
visibility at cool temperatures. In warm temperatures or intense direct
sunlight, the display may
become difficult to see.
Settings toward MIN (lower
numbers) will improve
visibility of the display in all
but extreme situations. If

searching.
VIEWING ANGLE has no impact on battery life.
EMERGENCY VIEWING ANGLE PROCEDURE- If your detector has been in the cold or
heat prior to use, you may not be able to see the
display to adjust VIEWING ANGLE. Press the
ON/OFF control, hold the TRIGGER and press
ARROW up. You can then use the ARROW
controls to find a VIEWING ANGLE level that
allows you to read the display. Squeeze and
release the TRIGGER to begin searching. Like the
BACKLIGHT, you will lose your custom VIEWING ANGLE setting if you change Programs.
You may need to use the EMERGENCY VIEWING ANGLE PROCEDURE to see the display.
Select the program you desire, use the ENTER
control to enter, Air/Ground Balance, then again
use the EMERGENCY VIEWING ANGLE
PROCEDURE if the display is unreadable.
VIEWING ANGLE is preset at average levels in
the factory preset programs. The display may be

appear on the display. There are two pages to the
PRO OPTIONS menu (PG. 1/2 Page one of two).
The ARROW controls are then used to select the
desired PRO OPTION category.
The five major categories have options specific to
their titles. For example, all the options under
AUDIO have to do with the way the audio circuits
of the instrument behave. Once a category has been

OFF - When OFF, the signal will remain original
size giving some indication of its size and shape.
Manual shrinking is completed by squeezing and
releasing the TRIGGER several times as the loop is
passed over the target. Manual shrinking can
completely eliminate the target. If the target no
longer responds after manual shrinking, move the
loop away from the target, squeeze and release the
TRIGGER, and again sweep the loop over the area.
If the target is a metal, it should again respond.

Self-Adjusting Threshold (auto-tune) smooths the
THRESHOLD, OFF (0), or ON (1-10).
S.A.T. SPEED
5
MIN
MAX
Tips - Recommended for
most conditions as it
provides greater stability
particularly in non-discriminate modes or when
sensitivity levels are
maximized. Typically,
faster S.A.T. SPEEDs
(higher numbers) improve
performance in more
mineralized ground.
Slower S.A.T. SPEEDs
(lower numbers) improve
performance in milder
ground conditions.
Without S.A.T. SPEED (a setting of 0), changes in
the ground (and the passage of time) will tend to
produce changes in the THRESHOLD sound. The
TRIGGER will have to be squeezed and released
repeatedly to maintain the THRESHOLD. This is
particularly noticeable in non-discriminate modes,
although S.A.T. SPEED will also tend to add
stability to discriminate modes. S.A.T. SPEEDs 1
through 10 will automatically correct for such
THRESHOLD changes.
S.A.T. (auto-tune) is a feature that has been used
on metal detectors dating back to the 1970's. It
adds a loop-motion requirement to modes which
are ordinarily non-motion. It is also known to
produce some variations in the responses to hot
rocks (rocks more mineralized than the surrounding ground) which change with different speed
selections.
Only enough S.A.T. SPEED required to maintain
stability is recommended. Typically normal coin
searching requires slower (lower number) speeds,
beach hunting and relic hunting require slightly
faster speeds (higher numbers), and prospecting
requires the fastest settings (highest numbers).

TO CHANGE PRESS ENTER
Tips - Great for coin,
jewelry, and relic searching. Can be used in
combination with MIXED
MODE.
Assigns each V.D.I. number its own distinct tone
or pitch. Target ranges can easily be identified by
their sound. The higher the V.D.I. number, the
higher the pitch of their sound. Reject targets still
break up or "cut-out".
Tone I.D. is used in the discriminate or motion
modes. When ON, each V.D.I. target number has
its own audio frequency or pitch (191 different
pitches). The higher the V.D.I. number, the higher
the pitch. Where a target indicates on the V.D.I.
scale can be immediately recognized. The sound
that rejected targets produce will still be canceled
or modified (broken up) by the discriminate circuit.
The 191 different pitches or tones activated with
TONE I.D. cannot be adjusted as to their pitch.
Each V.D.I. number's sound is predetermined by
the factory and is not adjustable, nor will they shift
with TONE (AUDIO FREQUENCY) adjustments.
TRANSMIT FREQUENCY settings will add slight
variations to these tones.

Voltage Controlled Oscillator produces a higher
pitched tone the stronger the target becomes.
Voltage Controlled Oscillator is a feature that will
only work in the non-discriminate modes. When it
is ON, the stronger the response the higher the
pitch of the sound. An excellent aid in pinpointing,
V.C.O. will only function when the trigger is
squeezed for pinpointing when activated in a discriminate mode.
D.C. SENSITIVITY settings will dramatically
change the performance of V.C.O. D.C. SENSITIVITY settings above a level of 35 may peak the
audio pitch too soon to allow V.C.O. to be useful.
D.C. SENSITIVITY settings of 35 or below (lower

TO CHANGE PRESS ENTER
Tips - If you have excellent
hearing and want to single
out deep targets by their
lower-volume responses,
use modulation. ON is the
default (standard setting)
for all factory Preset
Programs. If your hearing
isn't the best, the OFF
setting is recommended.
30
Allows motion modes to produce different volume
levels based on target depth.
Modulation is used in the discriminate or motion
modes. When ON, it allows the depth of the target
to dictate the volume of the response. Thus deep
targets can be easily recognized by their lowervolume sound. If OFF, the discriminate or motion
modes will produce the same volume of response
on all detected targets regardless of depth. The use
of MODULATION allows for the singling out of
deep targets in the standard discriminate mode. It
saves time by eliminating the checking of each
target with the depth indication in the pinpoint
mode.

7. AutoTrac
AUTO TRAC™ allows the instrument to automatically readjust the Ground Balance setting during
searching. This readjustment allows for natural
occurring changes in the ground mineral of an area.
By maintaining an accurate Ground Balance,
detection depth and stability are enhanced. AUTO
TRAC™ is recommended for typical search conditions. If, however, a great deal of decomposed
man-made iron is encountered, AUTO TRAC™

"TRACK" would indicate difficult ground. In
average ground it is desirable to see some tracking
occur (see TRAC SPEED).

Tips - It is desirable to

may TRAC less or more

32
Dictates when AUTO TRAC™ adjusts Ground
Balance.
Trac Speed allows adjustment of the amount of
ground mineral change required to cause
Autotracking to occur. At slower speeds (lower
numbers) it takes a significant change in the
ground to cause tracking to occur. At faster speeds
(higher numbers) it takes very little change in the
ground mineral to cause tracking to occur. The end
result, more tracking occurs at higher numbers than
at lower numbers. Too much tracking can cause
errors in the ground balance setting. Not enough
tracking can result in the ground balance setting
never catching up with changing ground. TRAC
VIEW is used to see how much tracking is occurring. Generally, a faster (higher number) TRAC
SPEED is needed for more consistent ground
conditions. Slower TRAC SPEEDS (lower numbers) is needed for more inconsistent ground
conditions. "TRACK" appearing every three to five
sweeps of the loop is the ideal setting when the
ground conditions will allow.

Tips - Recommended only

Allows AUTO TRAC™ to track ground minerals

TRAC OFFSET allows the AUTO TRAC™
feature to track the ground slightly more or less
than what would normally be considered perfect,
mostly for experts that prefer a slight offset.
A slightly positive offset can be used to enhance
the responses of small metals (gold nuggets) in
highly-mineralized ground. Positive is indicated by
a slight increase in threshold as the loop approaches the ground in the all-metal mode. Discrimination and depth may also be improved.
A negative offset may be used to eliminate particularly troublesome "hot rocks" in areas that are
otherwise difficult to search. Negative offset is
indicated by a loss or slight decrease in the threshold as the loop approaches the ground in the allmetal mode.

Prevents AUTO TRAC™ from tracking the

TRAC INHIBIT ON prevents the AUTO TRAC™
feature from altering Ground Balance during the
detection of targets. This prevents the possibility
of tracking to the corrosion associated with most
metals. TRAC INHIBIT ON is recommended for
most searching conditions. Some metals do not
corrode (GOLD) and since tracking is extremely
important in high mineral conditions, the ability to
turn TRAC INHIBIT OFF is available. OFF is
automatically selected in the Prospecting Program
and is recommended for prospecting.

COARSE & FINE G.E.B. (Ground Exclusion
Balance, or ground rejection) allows manual
override of the automatic balancing features to
select a specific Ground Balance setting.
COARSE allows major adjustments. FINE allows
minor adjustments near the COARSE setting.
Before attempting manual Ground Balance adjustments, turn off AUTO TRAC™ since it will alter any
manual changes you make. Manual Ground Balance
will begin at the setting selected by the automatic
(Air/Ground Balance) sequence. An Automatic Air/
Ground Balance performed after manual adjustment
will cancel the manual setting. To maintain a manual
setting, the Automatic Air/ Ground sequence must be
avoided by squeezing and releasing the TRIGGER
when, and if, the Air Balance instruction appears. Air
Balance instructions may appear during Basic Adjustment or Pro Options selections following the manual
adjustment.
When manually adjusting the Ground Balance, it is
necessary to make an adjustment in COARSE and/
or FINE, then squeeze and release the TRIGGER.
The TRIGGER can be held in, and the loop lowered and lifted over the ground to check for a
change in sound which would indicate imperfect
Ground Balance. To return to the Ground Balance
display for further adjustment, press either of the
ARROW controls. When perfectly Ground Balanced in a search mode, the TRIGGER can be
squeezed and held, and the loop lowered and lifted

Tips - Use for controlled

FINE G.E.B. is used to make smaller adjustments
to the Ground Balance range on either side of the
COARSE setting. The FINE setting combines with
the COARSE setting to determine the actual
ground rejection level. To determine exactly what
level the automatic Air/Ground sequence selected,
it is necessary to check both COARSE and FINE
levels.
Manual Ground Balance will rarely be used for
perfect balancing as the automatic balance is
extremely reliable. It is generally used to offset
Ground Balance for the same reasons AUTO
TRAC™ OFFSET is used.
In COARSE or FINE, lower numbers indicate a
Ground Balance setting toward the negative side of
the V.D.I. scale (iron). Larger numbers indicate a
Ground Balance setting toward the positive side of
the V.D.I. chart (salt). Bad ground conditions
(high mineralization) may be described as either
magnetic (negative or low numbers) or conductive
(positive or high numbers). COARSE and FINE
settings of 0 represent a ground rejection similar to
a V.D.I. number of -95. COARSE and FINE
settings of 255 represent a ground rejection level
similar to a V.D.I. number of +10. This V.D.I.
range from -95 to +10 represents the ground rejection range of this instrument. If ground balance
(either automatic or manual) occurs near the 255
COARSE setting, significant loss in sensitivity can
be expected to targets which indicate in the V.D.I.
number range of 1 to 10. However, manual ground
balance doesn't exactly work like a discriminator,
where V.D.I. numbers are simply REJECTED.
The actual phase of Ground Balance is out of
sequence with most targets; thus some responses
will occur even if COARSE & FINE G.E.B. are
matched exactly to a particular targets V.D.I.
number.

DISCRIMINATION - Will have a greater
impact on how the instrument operates

ON/OFF is located in the BASIC
ADJUSTMENTS, (page 19).
DISC. EDIT and BLOCK EDIT are
exceptions to the key-stroke rule in that
they do not have a graphic control knob.
However, ENTER must still be pressed
before adjustments are possible.
Select DISC. EDIT and press ENTER. Now use
the ARROW controls to view the V.D.I. numbers
from negative -95 to positive +95 that appear on
the right side of the display. These are the same
reference numbers that are listed on the top righthand side of the control box (V.D.I. SCALE or
target chart). For each V.D.I. number, a √ will
appear to the left indicating whether the current
program will ACCEPT or REJECT targets that
display that number.
Use the ENTER control to change any desired
V.D.I. number to ACCEPT or REJECT status.
If you do not save the entire Program into a Custom position, the changes you make in EDIT are
only in use as long as you continue to use that
program. The only exception being the temporary
short-term or volatile memory as previously described. If you make EDIT changes in Coin, and
then switch to COIN & JEWELRY, you lose all
editing you completed in the Coin Program. Each
time a factory Preset Program is ENTERed, all
unsaved settings are over-written by the factory
recommended settings. Only the Custom Programs
will save your custom settings through Preset
Program selections.
Accepting certain V.D.I. numbers will have an
impact on detection depth, particularly for very
deep targets that are difficult for the display to
identify. Positive +95 is one of these V.D.I. numbers. Some Preset Programs are set so that the
positive +95 V.D.I. number is rejected. The display
uses positive +95 for many different types of
36
Chapter 5 XLT® Pro Options
targets it cannot readily identify. Therefore, if
positive +95 is ACCEPTed, questionable targets
may be dug that indicate this number and can
produce some interesting recoveries. A good tip
regarding positive +95: If a target indicates 95,
and the depth display indicates it as being fairly
deep; dig it. If the depth display indicates it as
being fairly shallow, it is more likely to be trash or
a hot rock.
The first 30 to 40 negative numbers below zero also
impact detection depth. Most iron indicates further
into the negative numbers. Thus the first 30 to 40
negative numbers can often be ACCEPTed without
digging much iron. ACCEPTing from the positive
numbers down as low as minus 30 to 40 has the
largest impact on the lower end of the positive
numbers. Sensitivity to small jewelry is increased
however, sensitivity to foil is also increased. On a
beach or in a park that has lots of small foil,
ACCEPTing down to minus 30 to 40 may not be
practical. While ACCEPTing these minus numbers,
a reduced sensitivity setting may help eliminate
some of these small bits of unwanted foil.
The detector sees metals electronically; thus some
valuable and non-valuable targets may look identical to the detector. To select ACCEPT and REJECT V.D.I. numbers is to gamble that the areas
you select for ACCEPT will be good targets, and
the area you select for REJECT will be trash
targets. A factory program which uses the law of
averages usually produces more good targets than
trash. The EDIT feature allows you to fine-tune the
ACCEPT and REJECT settings for your area and
types of desired targets, further improving these
odds.
ACCEPTINGing all V.D.I. numbers will produce
the best overall detection depth however, with the
amount of trash in most areas, searching with no
rejection is seldom practical. TONE I.D. and or
MIXED MODE are more practical choices. The
idea of discrimination is to ACCEPT V.D.I. numbers most likely to be valuables and to REJECT the
V.D.I. numbers most likely to be trash. Digging
ease, and acceptability in an area will also decide
the amount of ACCEPTed V.D.I. numbers desired.
No metal detector can reject all trash while accepting all valuables. The deeper you want to detect, the
more trash you will need to accept and dig.

ARROW controls can then be used to drag that
ACCEPT or REJECT status as far as desired
through the V.D.I. number range. When a V.D.I.
number or range of numbers appear that you want
set differently, stop dragging with the ARROWs,
press ENTER to change the ACCEPT / REJECT
status, and then drag that new status as far as you
desire. ENTER changes ACCEPT / REJECT;
ARROWS drag that ACCEPT / REJECT status;
ENTER again changes ACCEPT / REJECT;
ARROWS drag that new ACCEPT / REJECT

BLOCK EDIT not only saves time if large sections

also allows peace of mind in the certainty of how
all the V.D.I. numbers are set. In the same amount
of time it takes to view all the V.D.I. number's

CAUTION
If you do not return to the LEARN

you have learned a target is extremely
important.
Iron alloys, such as steel bottle caps or
nails, should never be used for this
LEARN method of programming. Because of their inconsistent V.D.I. indications, iron alloys tend to scatter or otherwise confuse the discriminate program.
If this occurs, it is best to turn the detector OFF, back ON, and re-ENTER the
desired Program to return to the original
factory pre-set discriminate settings.
Specific target samples can be used to show or
teach the discriminator what metal targets you
desire ACCEPT or REJECT.
Select LEARN ACCEPT or LEARN REJECT with

RECOVERY SPEED
20
MIN
MAX
Tips - Use faster speeds
(higher numbers) for trashy
areas, slower speeds
(lower numbers) for low
trash areas and/or improved discrimination.
Speeds target responses, so several targets that are
close together can each respond.
When a metal is detected, it takes a fraction of a
second for the detector to process the signal before
it can respond to another metal target nearby. The
time it takes to process the first metal target signal
so that the second metal target signal can respond
is called RECOVERY SPEED.
There are advantages and disadvantages to fast
(high numbers) and slow (low numbers) RECOVERY SPEEDS. Faster RECOVERY SPEEDs work
well in high trash areas. However, they will have
some difficulties with very deep targets as well as
double responses on shallow targets. Slower
RECOVERY SPEEDs do not work very well in
high trash areas. However, they will have better
responses on very deep targets. Slower speeds also
have more definitive discrimination sounds. A
custom setting needs to be found that suits the
preferences of the individual and the conditions in
the area. As a general rule, the closer together the
metal targets are in an area, the faster the recovery
speed should be. The more spacing between targets, the slower the speed should be. Don't use the
fast speed if you don't need to.
In very trashy areas it is recommended to switch to
a loop smaller in size than the standard 9.5 inch
black loop. Smaller loops offer better separation
between targets. However, larger loops detect
deeper and cover more area with each pass. RECOVERY SPEED combined with a smaller loop
can be used to search severely trashy areas.

BOTTLECAP REJECT
4
MIN
MAX
Tips - If having difficulties
recognizing the broken
sounds of iron, try increasing BOTTLECAP REJECT.
Adjusts how strongly the instrument rejects or
breaks up on iron.
Most starting programs use the minimum setting.
As larger numbers are selected, more bias rejection
against iron occurs.
The advantage of higher BOTTLECAP REJECT
settings is that in high-trash areas more decisive
iron rejection occurs. Trash becomes easier to
identify by the broken sounds they produce.
The disadvantage of a high Bottlecap Rejection
setting is if an iron target is close to a good metal,
the high degree of bias against iron may cause the
detector to cancel both responses. Another disadvantage is that all targets, iron and non-iron, tend to
start sounding more broken at high levels of
BOTTLECAP REJECT. The operator needs to
fine tune BOTTLECAP REJECT according to their
preferences and the conditions being searched.
Some ground conditions make it difficult for the
instrument to recognize iron. BOTTLECAP REJECT allows compensation for these areas.

To provide greater specific target resolution, levels
of 86 and above will provide a third V.D.I. digit
(.0) to better evaluate targets. During EDIT only
the first two digits can be programmed ACCEPT or
REJECT.
As with all sensitivity levels, if set too high for the
area, the detector will become unstable and the
display indications unreliable.
Low ground mineralization is typically a good
indication that high V.D.I. sensitivity settings are
appropriate. Heavy mineralization or electrical
interference are conditions where a lower V.D.I.
Sensitivity setting is appropriate.
This feature is designed to allow adjustment of the
display stability. However, because the
instrument's display and audio tone are closely
associated in many of the audio modes, the V.D.I.
Sensitivity may increase or decrease overall audio
sensitivity.

dealt with by using similar
settings.

The D.C. Phase of the ground has a relationship
to the proper Ground Balance setting. This is of
particular interest to those who use the optional
COARSE or FINE G.E.B. (Manual Ground
Balance). Manual Ground Balance has a range
that covers V.D.I. numbers from -95 - +10. A
Manual Ground Balance Coarse setting of 0
equals a D.C. PHASE of negative -95. A Coarse
setting of 255 equals a D.C. Phase of +10. As
mentioned under COARSE and FINE G.E.B.,
Ground Balance is not the same as EDITing
these V.D.I. numbers for REJECT. However, if
your ground measures -90, ACCEPTing V.D.I. 90 will produce operational problems as the
detector will see the ground as a target. With the
same logic, if a target measures -90, and the
ground measures -90, and the detector is Ground
Balanced to this -90 ground, such a target will be
virtually invisible to the detector. These conditions
would be extremely rare however; the point is
there must be a difference between the target and
the ground for the target to be detected.
44
When D.C. PHASE is ON, and the TRIGGER
squeezed and released, normal searching begins.
When a target is located, or when the operator
wants to measure a target or the ground, the TRIGGER is squeezed and held as if to pinpoint. When
the loop is held stationary over the target or ground,
the D.C. PHASE is shown on the upper-right side
of the display. The depth reading can be used to
help center the loop over a target for more accurate
indications. The audio tone will also assist in
centering the loop over the target.
Metal targets in the ground will produce a measurement which represents the target indication ± the
ground measurement. To measure the target alone,
move the loop off to one side (being sure to hold
the loop directly on top of the ground mineral), and
release and re-squeeze the trigger. Then move the
loop back over the target. This should allow a
proper D.C. PHASE reading for the target alone.
The relationship between D.C. PHASE, Ground
Balance, V.D.I. number and Discrimination is
complex. Results are not always repeatable in
varied ground conditions. Ground and target responses can distort the detection field of the loop in
a number of ways, by bending, reflecting, absorbing
and thus altering the phase and amplitude the
detector measures. This in turn produces inconsistencies in the relationships of these features.

24. Accumulate
GRAPH ACCUMULATE
ON
OFF
TO CHANGE PRESS ENTER
Tips - ON is suggested,
since it takes several
sweeps of information to
recognize trends.
If ACCUMULATE is OFF, and AVERAGE
is OFF, then SINGLE SWEEP is active.
SINGLE SWEEP displays SignaGraph™
information received during the current sweep
of the loop, no more and no less. The next
sweep of the loop will clear all information
from the SignaGraph™ and list the information received only within that sweep. Fade is
not needed in the SINGLE SWEEP mode as
each pass of the loop will clear the display
and provide current information automatically. Several SignaGraph™ indication
samples occur during each sweep of the loop.
It is therefore normal to see one or more
SignaGraph™ bars, even in the SINGLE
SWEEP mode.
GRAPH AVERAGING
ON
OFF
TO CHANGE PRESS ENTER
Tips - Most beneficial
when used in combination
with ACCUMULATE.
AVERAGE ON is suggested as it reduces
indications uncharacteristic of a particular target,
which may occur due to
loop angle or target
positioning in the ground.
ON combines SignaGraph™ information over
multiple loop passes, OFF shows SignaGraph™
information only from the last sweep of the loop.
Accumulate allows the SignaGraph™ to continually
collect information. This collecting of information
continues from one sweep of the loop to the next.
Eventually, if only ACCUMULATE is selected,
the SignaGraph™ will completely fill, requiring
that the TRIGGER by squeezing and releasing to
clear it so that further information may be viewed.
FADE is suggested to be used in combination with
ACCUMULATE so that non-current information
gradually disappears and excessive TRIGGERing is
not required. FADE will gradually reset or clear the
SignaGraph™ to eliminate old information.
(Display section)
25. Average
Emphasizes the most common or predominate
SignaGraph™ indications.
AVERAGE does not necessarily allow showing of
all the available information on the SignaGraph™.
It averages the information received, and shows this
average on the SignaGraph™. When used in combination with ACCUMULATE it has more information to average, which results in more accurate
indications of trends. FADE is suggested to clear
the display of old information, rather than excessive
TRIGGERing.

FADE RATE

MIN
MAX
Tips - Recommended
for all but the SINGLE
SWEEP mode. Adjust
the rate of FADing so
that you have time to
view the SignGraph™
prior to it resetting.
However, do not set it
so slow as to show noncurrent information.
46
FADE allows past information to automatically
clear or fade from the SignaGraph™. Without Fade,
or with too slow of a FADE rate, the SignaGraph™
will fill with information that is no longer valid as
you sweep through a search area.
A minimum setting of 0 equals no fade at all. The
SignaGraph™ information will continue to appear
until the trigger is squeezed and released. A maximum setting of 14 selects a very quick fade rate.
The SignaGraph™ information will automatically
clear from the graph quickly. Ideally, a Fade Rate
should be selected that allows time to adequately
view the SignaGraph™ information yet still clear
the graph in a timely manner.

27. Transmit Boost
TRANSMIT BOOST
ON
OFF
TO CHANGE PRESS ENTER
Tips - Use ON unless
"OVERLOAD" is often
noted on the display, in
which case the OFF
setting should be
selected. Make sure the
OVERLOAD indication
is not caused by a large
metal target, that it is
caused by the ground
minerals.
Selects the intensity of the signal transmitted from
the loop.
There is a transmit and a receive coil within the
loop housing. If too much signal is transmitted for
the ground conditions (magnetic and/or conductive
ground), the signal will saturate the receiver and
thus eliminate good ground penetration (depth). By
turning OFF the TRANSMIT BOOST, ground
penetration in most cases will return. The receive
signal can then be optimized using PREAMP
GAIN, to provide the best depth possible in such
extreme ground conditions.
When "OVERLOAD" regularly appears on the
display, there are either very large strong metal
targets present or the ground mineralization is such
that the detector cannot properly operate. Sweeping
the loop higher above the specific OVERLOAD
response will identify a target. When OVERLOAD
appears on the display consistently due to ground
minerals, selection of TRANSMIT BOOST OFF
will improve depth and stability. During OVERLOAD the detector is not capable of responding to
metal targets. The OFF setting in most cases will
resolve such difficulties and provide detection
capabilities in extreme conditions.
Every time the TRANSMIT BOOST is altered, the
detector needs to be Air/Ground Balanced. Once in
a search mode, simply press ENTER to Air/Ground
Balance.

28. Transmit Frequency
TRANSMIT FREQUENCY
4
MIN
MAX
Tips - Use level number
"4" (6592.5 Hz) unless
interference results from
other detectors. Move
away from level "4" only
far enough to prevent
such interference.
Alters the normal operating frequency (6592.5 Hz)
to avoid interference from other metal detectors
operating close by. Operating frequency is the
frequency the detector transmits and receives its
signal.
Lower numbers equal
lower frequencies,
1 = 6027.5 Hz
2 = 6204.7 Hz
3 = 6392.7 Hz
4 = 6592.5 Hz
Higher numbers equal
higher operating
frequencies,
5 = 6805.2 Hz
6 = 7032.0 Hz
7 = 7274.5 Hz
Other metal detectors operating at the same frequency will cause interference. By shifting to a
different frequency such interference can be
avoided from detectors operating nearby.
The best performance will be achieved at the
standard number "4" setting. If however, you
cannot search due to interference from other detectors, use an alternate frequency.
Remember that once the trigger is squeezed and
released to return to a search mode, the last option
used can be accessed by pressing either of the arrow
controls. This ARROW RETURN feature can be
used to handily change TRANSMIT FREQUENCIES during a competition hunt.

29. Preamp Gain
Selects the intensity of the signal received from the
loop.
PREAMP GAIN
2
MIN
MAX
Tips - Higher levels
increase detection depth.
However, the detector
must be stable to be able
to recognize a target.
OVERLOAD should not
appear on the display
when only ground minerals are present.
PREAMP GAIN (called Signal Balance on some
models) is used to promote stability and performance. Like a sensitivity control, too much
PREAMP GAIN will result in unstable operation
and unreliable indications. Unlike a sensitivity
control, PREAMP GAIN will have a substantial
effect on OVERLOAD.
For maximum detection depth, fine tune the
PREAMP GAIN to the highest number setting
without causing OVERLOAD, and/or unstable
operation. More adjustment levels (range) are
available than what may be usable. You may never
encounter an area where maximum PREAMP
GAIN can be used. Electrical interference may
make it difficult to receive an Air Balance at high
PREAMP GAIN settings.
Selections such as MIXED MODE or AUDIO
DISC OFF may not allow as high a PREAMP
GAIN level as other selections. This is normal as
some of these modes naturally see more targets and
ground, and they may still provide superior performance and depth even with the lower PREAMP
GAIN selection.
If TRANSMIT BOOST OFF has been selected, it is
particularly advisable to fine tune PREAMP GAIN.
Every time the PREAMP GAIN level is changed,
the detector needs to be re-ground balanced. Once
in an operating mode, simply press ENTER to reground balance.
