The X-Terra detectors are Minelab’s fi rst products to incorporate VFLEX Technology.
VFLEX uses state of the art digital and mixed-signal components to enhance standard single frequency technology by replacing most of the analogue circuitry with digital signal processing. The small amount of analogue circuitry still employed has been very carefully designed and calibrated to obtain the outstanding sensitivity, stability and repeatability required to match the performance of the processing in the digital domain.
This radical departure from traditional approaches to metal detector design has been made possible by advances in electronics that power personal digital assistants, cell (mobile) phones and high-fi delity portable audio.

For the X-Terra user, this precision means dependable performance and improved immunity to environmental conditions such as ground mineralization, electromagnetic interference and temperature variations.
VFLEX requires coils that are accurately constructed and calibrated. Every time the detector starts up, the micro-controllers in the control box and the coil establish communication through a digital data link.
Information about the coil is sent to the control box, so the detector ‘knows’ what type of coil is attached and can set the correct operating parameters.
This optimizes the performance, and also makes the detector ‘future proof’, in that it will be capable of operating at diff erent frequencies* depending on the electronic properties of the coil.

Plug the two rubber washers into the holes on either side of the lower shaft yoke.
Slide the yoke into the yoke bracket on top of the coil. Ensure that the spring loaded pin in the lower shaft is underneath.
Insert the plastic bolt through the yoke and the yoke bracket.
Fasten with the plastic wing nut provided, being careful not to damage the thread of the bolt by over-tightening. This may need to be loosened to adjust the coil to a comfortable detecting angle.
The coil cable is directly wired into the coil and is not removable. Any attempt to disconnect this cable will void your warranty.
Ensure that the twistlocks of the shafts are loosened by rotating them counterclockwise.
Compress the spring loaded pin in the lower shaft and slide it into the middle shaft until the pin reaches the adjustment holes.
The pin will spring out and click into place.
Attach the middle shaft to the upper shaft in the same way.
Once shafts are assembled, lock them in position by rotating twistlocks clockwise.
The upper shaft assembly location uses
two spring loaded pins to strengthen the joint, one on either side of the shaft

Place the armrest onto the top of the upper shaft, lining up the central hole in the armrest with a hole in the aluminium shaft.
Position the armrest to suit your arm length.
(Holding the Detector, pg. 15)
Insert the screw up through the stand, upper shaft and armrest. Tighten the screw, being careful not to overtighten and damage the thread.
With the velcro side facing upwards, thread the armrest strap through both slots in the armrest. Ensure the end of the strap will be fastened outwards from your arm.
The X-Terra is designed to be used in both the left and right hand. This diagram shows the velcro strap threaded outwards for the left arm.
Connecting
With the LCD facing up, push the control box onto the end of the handle until it fi ts into place.

CONGRATULATIONS!
YOU HAVE SUCCESSFULLY
ASSEMBLED YOUR X-TERRA.
IT IS NOW READY FOR DETECTING!
Thread your arm through the armrest and strap. Grasp the handle of the detector and rest your forearm in the armrest.
Your elbow should sit just above the top of the armrest. Lightly tighten the velcro strap and secure it around your arm.

16
The correct position of armrest and length of shaft should allow you to swing the coil in front of your body without any uncomfortable stretching or stooping.
To adjust the length of the shafts, undo the twistlocks, compress the spring pins of the shafts and move them up or down to suit.
Once all shafts are clipped into position, rotate twistlocks clockwise onto the shafts until a fi rm clamping action is achieved.
To adjust the position of the armrest remove the armrest screw and move the armrest and stand to the desired position.
Think of the detector as an extension of your arm. It should be straight with your forearm and feel light and comfortable when you pick it up.
17
Shaft is the correct length
Once outside, practice sweeping the coil over the ground in a side-to-side motion, while walking forward slowly. Slightly overlap the previous sweep to ensure a full ground coverage. An approximate sweep speed is 3 seconds from left to right to left.
It is important to keep the coil close and parallel to the ground at all times. This will increase detection depth and response to small objects. Avoid excessive brushing of the coil on the ground, as this may result in false signals and inaccurate target ID’s.
A variation in coil height at the end of each swing may also cause confusing sounds and reduce detection depth.

There are many metallic objects inside the house (e.g. nails in the fl oor, reinforcing in the walls) that will result in overloading the detector’s electronics. There may also be interference from TV sets and other household appliances. In this environment the detector may give erratic performance and numerous false signals.
If the detector emits an overload sound
and displays OL (Error Messages, pg. 61)
move the coil away from the source of the overload.
It is best to only turn the detector on when outside, away from sources of electromagnetic disturbance.
Press POWER
A short start up sequence will display and a tune will be heard.
Once on, the detector will be in automatic detection. There will be no numeric reading until a metal object is detected.
Overloading is not harmful to the detectors electronics.

A good way to become familiar with detecting is to test the detector against a range of metal objects. This exercise is a simple lesson on how the detector interprets metal objects.
Gather a collection of diff erent metal objects, e.g. various coins, gold and silver jewellery, a rusted nail, pull-tab, brass button and aluminium foil.
Take the detector outside, away from known electromagnetic fi elds or metal objects.
to allow the coil to pass between the objects.
Pass the coil across the objects, one at a time, and observe the LCD and the detector’s sounds as it detects each object.
Note: If you are getting signals from a clear patch of ground, there may be unknown buried metal objects.
Before attempting to pinpoint or recover real targets it is important to understand how to interpret the audio and visual responses correctly.
If the detector is making popping and crackling sounds and displaying numbers when the coil is not over one of the metal objects, try reducing the detector’s sensitivity
Once stable, the detector will only sound and display numbers when the coil is passed over a target.
This test exercise can be used when
adjusting the detector’s settings (Sensitivity, pg. 44, Volume, pg. 46, Noise Cancel*, pg. 48,
Don’t worry if the detector isn’t producing a sound over the nail, this is because the detector begins in the default pattern

, a setting which rejects signals from common junk targets.
The X-Terra 50 has additional ways of stabilising the detector’s signals for
diff erent environments. (Noise Cancel*, pg.

Metal detectors work due to the fact that metal is conductive. Metal detectors create an electromagnetic fi eld, which penetrates the ground.
When the coil senses a change in this fi eld
(caused by a metal object) it sends a signal back to the control box which then alerts the operator. Metal detectors react to the size, shape and composition of objects.
Typically, the larger the object, the deeper it can be detected.
The X-Terra uses a single frequency (7.5kHz) as the standard operating frequency. This frequency has the ability to penetrate deep into the ground.
The frequency of a detector is the number of times a signal is transmitted into the ground and received back, per second
(measured in Hertz - Hz).
“BEEP

27
The X-Terra has a number of diff erent icons that have been designed to best represent and identify the metal objects in the ground.
Target ID
Buried metal objects are referred to as targets.
As the coil is passed over a target, it detects its conductivity and displays this as a number.
Target Identifi cation (ID) is used to distinguish one type of metal target from another.
Target ID numbers range from -4 to 44 on the
X-Terra 30 and -9 to 45 on the X-Terra 50.
Negative numbers represent ferrous targets and positive numbers represent non-ferrous targets.
The last detected target ID stays on the display until another target is detected. If the detector passes over a target that it rejects, the display will return to a blank detection screen represented by 2 dashes.
Target ID
The numeric identifi er of a particular metal object underneath the ground.
Depth indicator
A guide to how deep a metal object is under the ground.
The more arrows displayed, the deeper the object is likely to be from the coil.

2
Discrimination segment
Another identifi er of metal objects, each segment refers to a certain type of metal signal. Segments can be turned off (to accept targets) or turned on (to reject targets) which in turn accepts or rejects signals from the corresponding metal objects.
(A grey icon on the diagrams in this manual represents a fl ashing icon on the detector.)
28
In addition to the target ID, targets are also represented as a particular segment on a linear scale at the bottom of the display.
Each discrimination segment represents a level of conductivity and ferrous content.
Non ferrous targets are those that have no iron content, such as gold, silver, copper and bronze. Non-ferrous targets are often higher in conductivity and are represented by the right hand side segments.
Ferrous targets are those that contain iron, for example nails and scrap metal. They generally have a low conductivity and are represented by the left hand side segments.
Desired and undesired targets may appear anywhere along the discrimination scale, e.g.
Desired ferrous target - Canadian coin
Undesired ferrous target - iron nail
Desired non-ferrous target - gold coin
Undesired non-ferrous target - pull tab
Discrimination segments can be accepted or rejected, in turn accepting or rejecting certain targets.

During normal detection, the X-Terra operates with discrimination patterns. When a target signal is heard, it is an advantage to identify the target’s exact position. This is determined by using
PINPOINT
.
Enabling pinpoint instructs the X-Terra to temporarily disengage discrimination and become a non-motion detector. Targets normally discriminated against will emit a signal when beneath the coil.
In pinpoint, the detector gives a continuous audio response as opposed to a single beep while detecting. This continuous response indicates the strength of the target signal directly below the coil.
The pinpoint audio response is tone and volume modulated. The diff erence in tone and volume produced will help in locating the targets position and depth.
low coil high volume this target will produce a loud, high tone sound this target will produce a quiet, low tone sound low
The detector may become noisy if left in pinpoint. If this occurs, return to normal detection before trying pinpoint again.
Once the approximate target location is known, move the coil outside of that area and press
PINPOINT
.
Sweep the coil over the target location. The menu scale segments on the LCD indicate how close the target is to the center of the coil. The detector will only produce a high volume when the center-ring of the coil is directly above the target.
Taking note of the detector’s response, reduce the span of each successive pass of the coil until you are confi dent of the target’s location.
Make a mental note of the position or, if the ground is sandy, mark a line with your shoe or a digging tool.
Move to one side so that you can pass the coil over the target at a right angle to your initial direction. When the detector sounds you should know exactly where to dig.

again to take the detector out of pinpoint and then return to Step 1.
36
A trowel, knife or small spade are good tools for recovering targets.
Once a target has been located, clear the surface of loose material and check again for a signal. If there is no signal then the target is amongst the surface material. In this case, search the surface material until the target is located. If the target is still in the ground, check again with pinpoint.
The aim, when digging, is to leave the area of ground exactly as you found it. Using a sharp tool, cut a neat portion of grass or soil and place it on a plastic sheet. This prevents the material being scattered around and allows the hole to be refi lled.
Ask for permission before searching on private property.
A long blunt-tipped screwdriver is a good tool for soft ground. Probe the soil to fi nd the exact location of a target, if it is very shallow, simply prise it out.
Check the hole for the target. If it is not in the hole, place the detector on the ground with the coil fl at, pick up a handful of soil and pass it over the coil. Be sure not to wear rings, bracelets or a watch which will produce a signal. Repeat this procedure until the target is located.
Ensure that no other targets remain, then refi ll the hole. All soil and portions of grass on the plastic sheet should be returned to the hole as neatly as possible. Step lightly on the soil to compact it.
Leaving holes, or a scarred area may result in action being taken to prevent the use of metal detectors. Please ensure that you leave an area of ground as it was found.
Try to take all rubbish.

Target ID
Target signals contain both ferrous and conductivity information. This is digitally processed and results in a number being displayed that distinguishes between diff erent types of metal.
Target ID numbers range from -4 to 44 on the X-Terra 30 and -9 to 45 on the X-Terra
50. Negative numbers represent ferrous targets and positive numbers represent non-ferrous targets.
Numeric ID
These numbers have another function.
They are also used when adjusting the menu settings (sensitivity, volume, noise cancel* and ground balance*) showing the numerical value selected.

All Metal
AM indicates that the all metal pattern has been selected. This pattern has no discrimination and will allow signals from all types of metals, both ferrous and non-ferrous.
Patterns
Preset discrimination patterns are used to suit diff erent search preferences. X-Terra 30 has 1 pattern, X-Terra 50 has 2 patterns
(Preset Discrimination Patterns, pg. 30).
Depth Indicator
The depth indicator is a relative guide to how deep a target is. The more arrows displayed, the deeper the target is likely to be.
1 arrow is approx. 0-2” (0-5 cm)
2 = 2-4” (5-10 cm)
3 = 4-6” (10-15 cm)
4 = 6-8” (15-20 cm)

The X-Terra detectors are highly sensitive and therefore have a wide sensitivity adjustment range. It is important to set the correct sensitivity level for your detecting conditions.
Sensitivity is the detector’s level of response to a target and its environment. Real targets are interpreted as distinct beeps. Interference or false targets are interpreted as crackling or popping noises.
Tiny ferrous junk targets may be detected when the sensitivity is set to a high level. The detector will also be aff ected by minerals in certain soils and signals from other electric appliances.
X-Terra 30
Sensitivity range = 0-10
Factory preset = 6
X-Terra 50
Sensitivity range = 0-20
Factory preset = 12
Some experimentation with the sensitivity may be required for diff erent areas. For beginners, start with a low setting and increase progressively.
Decreasing the X-Terra’s sensitivity may help stabilise the detector, reducing false signals and interference, and assisting in diff erentiating between signals caused by soil mineralisation and those of metal targets.
Choose the highest stable sensitivity setting to ensure the detectors’ optimum performance.
For beach detecting, a setting below 10 may be required. In high trash areas, such as modern parks, a setting below 6 may be required, especially when searching for shallow coins (X-Terra 50 settings).
The highest sensitivity settings,
(7-10 = X-Terra 30)
(15-20 = X-Terra 50) should only be used in the quietest, most stable conditions.

Volume is the level of sound the detector gives when a target is detected. The volume control limits the potential loudness of target signals.
The X-Terra has proportional target signal volume. The sound produced by a distant target starts softly. As you get closer, the volume level increases rapidly until it reaches the maximum level that has been set.
The sound produced by the detector in pinpoint or ground balance will vary in volume and tone depending on the signal strength (from a target or ground mineralisation). This volume range is proportional to the maximum volume setting.
The X-Terra is able to save separate settings for both the speaker volume and headphone volume, switching from one to the other as soon as the headphones are connected
(Accessory Headphones, pg. 66).
Set the speaker volume without headphones connected. Set the headphone volume with the headphones connected. Use the exercise
(pg. 22) with diff erent targets to confi rm both
the speaker and headphone volume settings.
When the detector battery is low (indicated by the low battery icon) the speaker volume limit will be reduced. This saves battery power and extends detecting time.
You may choose to override this and increase the volume limit, but you then risk the detector shutting down earlier.

Noise cancel channels = -1, 0, 1
Factory preset noise cancel channel = 0
The detector may become noisy or erratic due to electrical interference from powerlines, electrical equipment or other detectors operating close by. This interference is interpreted as a crackling or popping noise.
Noise Cancel* allows you to change the noise cancel channel so that you experience less interference. Three channels are available, represented by the numbers -1, 0 and 1 and are also indicated on the menu scale.
It is best to choose a channel with the coil in the detection (horizontal) position because interference received in a vertical position may be diff erent from the interference received in the horizontal position.
The coil should be held in the air and away from large targets when changing channels.
There is no loss in depth or sensitivity if the noise cancel channel is changed.

The X-Terra 30 has a fi xed ground balance that allows adequate operation over most types of soils.
The X-Terra 50 has an adjustable ground balance which helps in compensating for false signals.
When the detector is unbalanced, it will detect targets, but it may also register false detections due to ground mineralisation.
These false detections are displayed as -9 in all metal or two dashes when using the factory preset patterns. This will cause good targets to be displayed only briefl y and with clipped sound.
Ground balancing the detector reduces false detections and enables good targets to be displayed and heard correctly.
Ground balance settings aff ect both normal discrimination detection and pinpoint operation.
an area with the X-Terra 50, try reducing sensitivity
Ground balance range = 0-20
Factory preset = 6
When detecting on the beach, adjusting ground balance may not give signifi cant improvements. Try adjusting sensitivity and altering patterns for best results.
Highly mineralised soil may produce false signals and distract from real targets.
Mineralised ground and ‘hot rocks’ may register as -9 when detecting in all metal. This is more likely to happen at high sensitivity settings and with an unbalanced detector.

Start Up Sequence
When the detector is turned on, there is a short three note tune during its start up sequence.
Positive Acknowledgement
The detector emits a short beep for every accepted key press.
Negative Acknowledgement
The detector emits a low double beep to indicate an invalid keypress.
Completed
A three note tune indicates the completion of a function (e.g. noise cancel* channel calibration).
Patterns Erased / Factory Preset
A six note tune will announce when these settings are complete.
Error
A six note tune will sound to indicate
a detector error (Error Messages, pg. 60).
Overload
If the coil is passed across a large shallow target, the detector will give a repeating buzzing sound. This indicates that the target signal is too strong for the detector to interpret.
Low Battery Signal
When the battery power becomes low, there will be a short announcement tune
(descending tones) every 60 seconds.
Low Battery Shutdown
A long announcement tune (descending tones) will sound just before the detector shuts down.
Target Response
This is the sound given by the detector when a target is located and not discriminated against (rejected). Generally a target that is highly conductive (e.g. a large silver coin) emits a high tone beep. A low tone beep is produced for ferrous targets.
Pinpoint Response
When in pinpoint, the detector emits a variable tone, that increases in pitch and volume as the coil gets closer to the target.
Noise
A random jittery sound indicates that the detector is picking up external interference.
Sensitivity or noise cancel* should be adjusted.
False Detections
A partial or chopped non-repeatable signal.
Two dashes will indicate on the LCD to indicate a rejected target.

The X-Terra is capable of using diff erent types of AA batteries:
1.5 V Alkaline
1.5 V Carbon
1.5 V Lithium (non-rechargeable)
1.2 V NiMH (rechargeable)
1.2 V NiCad (rechargeable)
The adjacent graph is a representation of how both types of batteries may discharge over time. How the detector is used will aff ect how long the batteries last for.
Rechargeable Lithium Ion batteries will give a combined voltage above 8 V and therefore cannot be used with the X-Terra
When the detector battery is low, the speaker volume limit will be reduced, to save battery power and extend detecting time.
The headphone volume is not aff ected.
The use of headphones will increase battery life.

The X-Terra is a high quality electronic instrument, fi nely engineered and packaged in a durable housing. Taking proper care of your X-Terra is common sense.
The X-Terra’s storage temperature is
-4˚F to 149˚F (-20˚C to +65˚C) and the operating temperature is 32˚F to 113˚F
(0˚C to 45˚C). Do not leave the detector in excessive heat or cold for longer than necessary. Try to avoid leaving it in a closed trunk or in a car sitting in sunlight.
Covering it when not in use will help protect it.
The coil can be submersed in water up to 20” (0.5m), yet the control box is not waterproof. Although it has been designed to be weather resistant, it is advised to protect the control box in wet conditions. A protective control box
cover is available. (Protective Accessories, pg. 68)
Never allow the detector to come into contact with gasoline or other petroleum based liquids.
Keep the detector clean and dry and avoid getting sand and grit into the shafts or fastenings (e.g. yoke, twistlocks). Do not use solvents to clean the detector. Use a damp cloth with mild soap detergent.
The display window may be prone to scratching or damage if not treated with care. A protective control box cover is
available. (Protective Accessories, pg. 68)
Ensure the coil cable is in good condition and not subject to undue stress (particularly where it is connected to the coil).
Always remember to turn off the detector before changing coils.
Previous Minelab coils will not function with the X-Terra detector.
Old, fl at or faulty batteries may cause many detector problems, through electrolyte leakage. Take the batteries out if the detector will not be used for long periods of time (e.g. more than 1 week). Ensure that only good quality batteries are used and that they are replaced when the low battery signal
Do not use rechargeable Lithium Ion batteries as their voltage is too high.
Non rechargeable Lithium batteries may be used.

Headphones
have many advantages.
They block out external noise such as wind closely to target signals. Headphones also minimise disturbance to other people in the area and they extend battery life.
The X-Terra is able to save separate settings for both the speaker volume and headphone volume, switching from one to the other as soon as the headphones are connected.
Ensure that the headphone volume does not reach an extremely loud level. This may increase the risk of hearing damage.
Connecting Headphones
Always use headphones with a ¼“ jack.
Open the rubber headphone cover located on the left hand side of the control box.
Plug the headphone jack into the socket.
When the detector is turned on, the headphones icon will appear on the LCD to indicate that the headphones are connected.
When not using headphones, keep the rubber cover closed to protect the control box electronics from moisture and dust.

Skid Plate
A skid plate comes as standard with the detector. If it wears out from excessive sweeping along the ground, accessory skidplates are available for purchase.
Environmental Cover
Protects the control box from environmental conditions such as rain and dirt.
Accessory coils come in diff erent types (Double D and Concentric), sizes and frequencies*. These coils are suitable for diff erent ground conditions and specifi c targets.
To attach an accessory coil:
Turn the detector off using POWER .
