TO OUR CUSTOMER:
We would like to extend our thanks to you for purchasing the LTD 260. This product is a
highly sophisticated instrument which is designed using the criteria “simplicity of operation”.
It is very important that you review this manual carefully and thoroughly prior to using your
President instrument. Successful instrument operation can be achieved with proper
installation, background education, and a thorough understanding of how the equipment
operates.
Your LTD 260 is an aid to navigation and does not reduce the need for caution or judgment.
No electronic navigation system is absolutely reliable; outputs may occasionally be incorrect.
The careful navigator should never rely solely on one device, to the extent of endangering life
or property. Please remember that any time a display reading flashes on and off, the outputs
may be in error and should not be used for navigation. We recommend that you use this
system in combination with marine charts, and knowledge of the area where your are
boating.
Again, we want to thank you for purchasing a President product and are confident of your
satisfaction.
Sincerely,
PRESIDENT

INSTALLATION:
LTD 260
First, find a location on your dash panel which will give clear viewing and access to the LCD
window. After finding the right location for the indicator unit, mark a 2 in. hole to be cut out. Check
behind the panel for any cables or wiring which could be damaged and then cut out the 2 in. hole.
Test fit the unit in the hole and make any adjustments with our saw or drill. Extending out of the
back of the instrument, you will notice a brass shaft. First attach the U-shaped mounting bracket
over this shaft, place the washer on the shaft and then tighten the nut until the U-shaped bracket
presses tightly to the back of the dash panel.. Look at the front of the instrument to ensure that it
is aligned properly and then tighten securely.
INSTALLATION:
WIRING
On the rear of the unit, locate the terminal lugs extending out of the rear of the instrument. These
terminal are used to connect the impeller wires.
When shipped from the factory, the transducer is wired with three female lugs attached that need
to be inserted into the male terminal located on the rear of the gauge. Exercise caution when
installing these connectors since improper wiring of the transducer to the wrong terminals can
cause internal damage to the instrument which could cause the unit to fail when power is applied.

INSTALLATION:
POWER SOURCE
BATTERY CONNECTION/POWER REQUIREMENT
Because the LTD 260 has no ON/OFF switch, you will need to wire it directly to a power source
which will turn the unit on as power is applied. It may be a power source which will turn the unit
on as power is applied. It may be convenient to wire the power cable directly to the Ignition Switch
so that when you turn the boat on, the depth sounder immediately starts working. Some boats
have already been prewired and labeled for a depth sounder so that when the switch is turned
ON, the depth sounder receives power.
1.
Connect the main unit to a 12 volt battery using the power cable supplied with your unit. You
may extend this cable as necessary, but you must observe proper polarity (i.E., red is
positive, black is negative).
2.
Connect the BLACK wire to the negative (-) battery terminal.
3.
Connect the RED wire to the positive (+) battery terminal.
4.
Make sure the connections are clean and tight so they do not vibrate loose during the boat’s
operation. Occasionally clean any accumulated corrosion from the battery terminals.
5.
If for some reason the fuse is blown, replace with a 1 amp fuse, normal blow.
DO NOT OVER FUSE! Because the unit consumes .25 amps of current when it is on, you will
want to keep your battery fully charged.
GENERAL INFORMATION:
DEPTH SOUNDER TRANSDUCER
UNDERSTANDING SONAR:
All depth sounders emit Ultra Sonic Sound signals by a transducer into the water located under
your boat. These sound signals travel through the water at a rate of 4,800 feet per second. The
depth sounder transmits a signal and receives a returning echo. The unit calculates the amount of
time in microseconds for the signal to travel to the bottom and return back to the transducer. It
then converts this time into depth and displays it on the screen.
It may help to imagine these sound signals bouncing up and down from the transducer to the
bottom by comparing it to a ping pong ball bouncing up and down from the floor. The closer the
ball is to the floor, the less time it takes for it to return. The higher the ball is bounced, the longer
time it takes for it to return. Bouncing a ball off a hard surface such as cement is the same as
bouncing a signal off a sandy or hard bottom. Bouncing this same ball off carpeting creates a
totally different effect. The ball (echo) returns with less force (weaker echo). The same analogy
applies to an echo bouncing on a muddy or grassy bottom - the echoes are weaker.

AIR ECHOES:
Air echoes can be caused by too much turbulence under the face of the transducer. It is important
to know that ultra sonic signals from a transducer will not penetrate air. They react to air in the
same manner as they react to a hard bottom described above. Therefore, if your transducer is not
mounted properly and you are getting turbulence (air bubbles) under your transducer, you may
get false readings simply because signals are being returned by the turbulence and never
reaching the bottom.
Adjusting the Shallow Water sensitivity can reduce this problem. Adjustment of the transducer
location can also help solve these false readings.
TRANSDUCER REPLACEMENT/IDENTIFICATION TAG
On most transducers manufactured after 1987, the operating frequency and part number is
attached to the cable or is printed on a mylar tag near the connector end. Do not remove this tag
since it identifies the transducer and will help you identify the operating frequency of the
transducer. (Improper frequency will cause your instrument to not operate properly.) Removal of
the identification tag will void the warranty.
SALTWATER MAINTENANCE/ANTIFOULING PAINT
Antifouling Paint: If the vessel is kept in saltwater, sea growth can accumulate rapidly on the
transducer face and seriously reduce performance in a matter of weeks. If fouling does occur, use
a stiff brush or putty knife to remove this growth. Wet sanding of the fouled transducer face is
permissible with #220 or finer grade of wet or dry emery paper. (Use plenty of water.) Coating
transducers with antifouling paint is often necessary to achieve consistent performance. All anti
fouling paints have a solvent base and solvents attack encapsulation materials and plastics to
varying degrees. If you need anti fouling protection use only paints with a mineral spirits base; do
not use acetone vinyl based paints. Glouchester (RULE) 7 is a hard, mineral spirits based paint
that we have found to be practically transparent to acoustic energy. Never apply paint to the
transducer by spraying; use a brush or roller. A sprayed surface “wets” very slowly and there are
often microscopic air pockets under the surface which attenuate the sound energy.

INSTALLATION:
DEPTH TRANSDUCERS
TRANSDUCER WETTING
Immediately before your vessel, thoroughly wipe the face of the transducer with a detergent type
liquid soap. This reduces the amount of time required for the transducer to establish good contact
with the water. If this procedure is not followed it may take several days for the complete “wetting”
to occur, resulting in reduced performance of the instrument.
There are a variety of transducers available for use on the many styles of boats available and the
preference of the boat owner. The three most popular styles are:
●
●
●
TRANSOM MOUNT: Ideal on boats with outboard engine or on I/O driven boats installed on
the stern of the boat)
THROUGH THE HULL: Installation is ideal for boats with Inboard engine(s)
INSIDE THE HULL: Often called Shoot Through Transducer can be used effectively if
procedures for installation are followed carefully.
“STYLE” OF THROUGH-THE-HULL TRANSDUCERS:
Transducer manufacturers build many different styles of transducers. The two most popular styles
of Through the Hull transducers are Low Profile types which typically are 1 3/4” or 2” in diameter
of Stem Type transducers which typically have a ¾” pipe thread and require a fairing block to level
it.
“MATERIAL” OF THROUGH-THE-HULL TRANSDUCERS:
The two most popular materials used are nylon and bronze.
●
WOODEN BOATS require the use of a bronze transducer or bronze fittings due to the fact
that when the boat is out of the water, the wood will dry out. When the fitting is installed and
the boat returned to the water, the wood will swell and possibly crack a nylon type of
transducer. Therefore, bronze is recommended for all wooden boat applications.
●
LARGER FIBERGLASS BOATS often prefer bronze transducers and fittings due to the size
of the boat and the total number of fittings used in the installation.
NYLON OR BRONZE - LOW PROFILE TRANSDUCERS
Ideal for high speed sport boats and sailboats, this style of transducer is designed to be mounted
flush against the hull without a fairing or leveling block. The hull deadrise angle must not exceed
15° in order to use this transducer fitting.
●
SAILBOATS: Normally a maximum beam amidships or in front of the keel.
●
POWERBOATS: Off centerline, 6”-12” and before the first lifting strake (flat area). Do not
install it on a lifting strake since this is the area where air bubbles travel from the bow to the
stern in order to provide a smooth ride.

WARNING: DO NOT INSTALL UNDERNEATH A GASOLINE OVERFLOW AS THIS WILL
DESTROY THE PLASTIC MATERIAL OF THE TRANSDUCER AND THE BRACKET AND IS NOT
COVERED UNDER WARRANTY. Also, do not use LOCKTITE or any similar adhesives on the
mounting hardware as these materials also destroy the transducer.

Attach the transducer to the bracket as shown.
WEDGE FORWARD: The style of the transducer with the wedge installed pointing toward
the bow is ideal for aluminum hulls, deep-vee hulls, and flat bottom boats. The wedge allows
turbulence and water to flow around the face of the transducer and will give high speed
performance.
Keep the face of the transducer clean and do not paint unless you use paint designed for
transducers as described in the section on Transducer Painting.
Keep the transducer cable as far away as possible from engines, motors, and other wires.
If you leave your boat in the water, follow the instructions for transducer maintenance and/or
painting the face of the transducer with transducer paint designed for this purpose.
Just before launching your trailerable boat, thoroughly wipe the face of the transducer with a
detergent type liquid soap to clean the face of the transducer. This reduces the amount of
time required for the transducer to establish good contact with the water.
Transducers can be installed on either side, although on single engine boats, the STARBOARD
(right) side is preferred due to the potential of engine cavitation caused by the rotational pitch of
the prop. (i.e. The turbulence caused by the transducer could cause your boat’s engine to
cavitate if the transducer is on the Port side and the rotation of the prop is clockwise.)
WARNING: DO NOT PUT UNDER FUEL OVERFLOW!!!

INSTALLATION:
THROUGH-THE-HULL TRANSDUCERS
In mounting a transducer through the hull (through-hull), it is important that it is done correctly
because the location of the transducer on the hull will determine how well the entire unit will
perform. There are several factors involved in choosing a good location for a through hull
transducer. In general, powerboats should have the transducer mounted in the last 1/2 - 2/3 of the
hull below the waterline, but always forward of the props and shafts. Make sure the above
guidelines are followed. Sailboats should have the transducer mounted in the first third of the hull
below the waterline, if possible about two feet in front of the keel.
GUIDELINES FOR THROUGH-THE-HULL:
1. The transducer face must always have a smooth flow of water over the face of the
transmitting surface. Bubbles will cause the instrument to read improperly and report
erroneous readings.
2. Never mount a transducer in direct line or withing 4 feet behind another through hull fitting,
the keel or rudder, zinc anodes, or other projections that would cause turbulence around the
transducer when the boat is under way.
3. Never mount a transducer in a recess or cutaway on the hull so that the face of the
transducer is shielded from direct contact with the flow of water.
INSTALLATION: LOW PROFILE TRANSDUCER
Mount the transducer through-the-hull using the following steps:
1. Drill an 1/8” pilot hole in the preferred transducer location.
2. Drill an appropriate sized hole through the hull using the pilot hole as a guide.
3. Have some type of soft backing plate or thin piece of plywood (3-1/2” x 3-1/2” x ½” thick)
available to strengthen the inside of the hull around where the hole was drilled. This serves
the dual purpose of allowing the transducer to conform to the inside of the hull, while
preventing the transducer locknut from unwinding.
4. Route the transducer cable through the hole in the hull. Do not pull on the cable as this may
cause internal damage to the transducer by causing an internal wiring short and require a
new transducer to be installed.
5. Apply a good grade of underwater marine sealant (polysulphide compound) to the flange of
the transducer. Use enough sealant so that it beads out around the transducer as you
tighten from inside of the hull.
6. Put the nut on the transducer from the inside of the hull. If nylon, hand tighten only. If
bronze, tighten with a wrench.
7. Clean off any excess sealant from around the transducer.
IMPORTANT: AFTER LAUNCHING THE BOAT, BE CERTAIN TO CHECK THE TRANSDUCER
LOCATION FOR LEAKS.

INSTALLATION:
POWERBOAT BRONZE TRANSDUCERS
This style of transducer is popular as a replacement transducer since it was the primary style
used on older boats and the stern will fir the same size hole as the previous defective or obsolete
transducer. In order to provide good, steady readings, it requires the use of a fairing block.
Without a fairing block, the large portion of the transducer is unprotected and runs the risk of
being hit off by objects in the water. Fairing blocks are best made out of hard wood such as oak.
The shape of the block will be determined by the shape of your hull and the style of transducer
you choose.
●
WOODEN BOATS require the use of a bronze transducer or bronze fittings due to the fact
that when the boat is out of the water, the wood dries. When the fitting is installed and the
boat returned to the water, the wood will swell and possibly crack a nylon type of transducer.
Therefore, bronze is required for all wooden boat installations.

6.
Drill a 1/8” pilot hole in the preferred transducer location. Reference previous section on
determining the best location for your type of boat.
Drill a hole “slightly” larger than the stem of the transducer. Be careful not to make it too
large as you will run the risk of water leaking into the hull.
Cut the fairing block to the shape of your hull and insert the cable and stem of the
transducer through ½ of the fairing block.
Apply a good grade of underwater marine sealant (polysulphide compound) to the flange of
the transducer and to the surface of the leveling block where the block touches the outside
of the hull. Apply enough sealant so that it will bead out around the transducer as you
tighten the transducer nut.
Put the remaining ½ of the fairing block on the inside of the transducer along with sealant
next to the hull. Tighten transducer nut lightly with a wrench.
Clean off the excess sealant from around the transducer.
IMPORTANT: AFTER LAUNCHING THE BOAT, BE CERTAIN TO CHECK THE TRANSDUCER
LOCATION FOR LEAKS.

INSTALLATION:
INSIDE THE HULL TRANSDUCERS
This type of transducer is very popular since it does not require the drilling of a hole such as the
through-the-hull transducer. However, you should consider the disadvantage due to the possible
loss of sensitivity which could cause a measurable depth loss in terms of maximum depth
capability. The success of inside the hull installation is also greatly dependent upon the purity of
the hull directly below the transducer and the type of hull.
When performing an inside the hull installation, you must use the special INSIDE THE HULL
TRANSDUCER since internal to the housing is a transducer crystal which is wider in inside
diameter that other styles of transducers and is designed to transmit the pulse through the hull.
Do not attempt to use a transom mount transducer as the crystal Is too small to insure optimum
instrument results.
Make sure that the transducer mounting location is at a point where a minimum of air bubbles
occur beneath the installation location. For example, do not choose an area above a lifting strake
because this is an area where air travels underneath the hull and could cause erroneous readings
or not allow the pulse to transmit and/or be received back to the unit.
DO NOT USE INSIDE THE HULL MOUNTING ON ALUMINUM, BALSA CORE OR WOODEN
HULLS, OR HULLS WHERE THE DEAD RISE ANGLE IS MORE THAN 15.
HOW TO INSTALL INSIDE THE HULL TRANSDUCER:
1. Select a relatively “thin” area of the hull. Avoid any built up areas that have been added to
strengthen the hull.
2.
The transducer must be below the waterline and in an area where it will always have water
underneath its surface.
3.
Mount in an area as flat and horizontal as possible. The greater the angle (deadrise) of the
hull, the greater the loss in sensitivity and maximum depth.
4.
We recommend that you perform a test to determine the accuracy of readings before
permanently installing the transducer. Do this by either placing the transducer in a plastic
bag of water or putting axle grease on the face of the transducer. Then try the unit in this
location to ascertain the readings in shallow water and deep water.
5.
After finding the optimum location, sand and clean the installation surface until it is smooth.
To insure a proper bond, clean and dry the bonding surface. Remove any oil residue on the
surface and clean an area roughly 4 inches in diameter. Finish this cleaning process by
wiping this area down at least twice with an acetone or lacquer thinner. DO NOT USE ANY
STRONG SOLVENTS IN CONTACT WITH THE PLASTIC OF THE TRANSDUCER SINCE
SOME SOLVENTS WILL WEAKEN AND DESTROY THE PLASTIC. Also make sure that the
ambient temperature is above 60° F (15°C).
6.
MIX THE TWO PART EPOXY SUPPLIED WITH THE TRANSDUCER FOR AT LEAST 3
MINUTES. If this is not done, proper bonding of the transducer to the hull will not occur and
false readings can be caused.
11
LTD260.qxd
12/15/98
8:24 AM
Page 12
7.
Apply the mixture to the clean location on the hull and to the face of the transducer in a
small amount.
8.
Press the face of the transducer into the spot of epoxy and slowly rotate it ¼ turn to remove
any air bubbles and until the transducer is physically against the hull or with ¼” of the hull.
When the epoxy has cured, it should be permanently bonded to the hull and hard to the touch.
Test the epoxy which extends out of the underside of the transducer with a screwdriver to insure
that it can’t be dented and is totally hard. Epoxy which is not hardened will eventually come up
and cause improper readings.
OPERATION:
How to set the alarm
HOW TO SET THE SHALLOW WATER ALARM
Located just below the LCD window are two keys labeled “DOWN” and “UP” Alarms. These keys
are used to set the Shallow Water depth alarm so that it will alert you if you enter water shallower
than your preset alarm.
To set an alarm, depress the “DOWN” key. You will note that the LCD will show an alarm depth of
A03. Pressing the “DOWN” key continuously will cycle the alarm setting deeper by one foot
increments fro A03 through A10 feet (ie: 3, 4, 5, 6, 7, 8, 9, 10). After A10, alarm setting are by two
foot increments (ie: 10, 12, 14, 16, 18, 20 feet). The alarm setting jump by five foot increments (ie:
A20, A25, A30). When you see a digital readout on the LCD proceeded by an A, this is your
ALARM depth.
To decrease the alarm setting, depress the “UP” key and the display will show these number in
decreasing value so that the alarm is shallower. Several seconds after you depress either the
“UP” or “DOWN” keys, the instrument will display the actual depth reading.

GLOSSARY
A partial list of terms used is presented herein.
BEAM ANGLE:
A transducer beam angle is shaped in an inverted cone (narrow at the top and
larger at the bottom). Most of the energy from the instrument is reflected back
to the transducer when it hits bottom. There are different beam angles for
different purposes. Generally, narrow beam angles are used on digital depth
sounders, medium beam angles for deeper depth, and wide angles for
applications where there is a need to look at a larger area below the boat.
GAIN
(SENSITIVITY):
Gain is another name for sensitivity control. The deeper the water, the more
gain you will require.
RANGE:
The total depth capability, depending on bottom conditions. Maximum depth
tends to decrease as the bottom becomes softer.
THROUGH
HULL
FITTINGS:
Plastic through hull depth transducers should be mounted in fiberglass and
metal hulls only. Plastic should never be used in wooden hulls as the swelling
of wood may overstress the plastic housing. Do not use bronze housings in
aluminum hulls since electrolytic corrosion will occur.
TRANSDUCER:
All depth sounders emit ultrasonic sound signals that travel through water
looking for a strong return echo (impulse). Inside the transducer is a crystal
element that transmits as well as receives these pulses. The unit calculates the
amount of time for the signal to travel to the bottom and return back to the
transducer. It then converts this time into depth and displays it on the screen.
TRANSDUCER
FREQUENCY:
The rate at which the sonar vibrates. It is critical to installation that the
frequencyof the transducer and the frequency of the instrument be the same.
Sonar instruments are designed to operate on a frequency which can provide
different results such as shallow or deep water performance, etc. It is best not
to have two of the same frequency transducers on the same vessel, unless you
plan in advance for this type of installation with a Switch Box so that you can
switch from one transducer to the other.

TROUBLESHOOTING:
SYMPTOM:
CHECK:
GENERAL OPERATION
Unit does not turn on at all. No beep, no display.
Make sure the unit is actually receiving power. Check the inline fuse, and the
circuit breaker panel on the boat. Make certain the unit is receiving 11 to 16
colts of CLEAN DC. Make sure the DC polarity has not been reversed. Check
for corrosion on the power connector, and clean if necessary.
SYMPTOM: “0.0” FLASHING in display window.
POSSIBLE REASON: The unit is not receiving an echo which could be caused by a variety of
reasons.
1. As previously described, this could mean that the Sensitivity Adjustment was turned too
much in one direction, actually squelching out the echo.
2. The transducer could be defective, therefore, not transmitting or receiving echoes.
3. The installation of the transducer could be incorrect, thereby not allowing a pulse to be
transmitted or received.
4. The unit could be defective and need to be returned to the factory for repair.
HOW TO SOLVE:
1. Correctly adjust the Sensitivity Control so that the number in the display window start to
appear and are reading the correct depth.
2. Try a “known good” transducer hooked up to the gauge and see if the depth appears in the
window. It is important to “wet” the transducer immediately before immersing in the water.
3. Check to insure that the transducer is installed as per the instructions in this manual. Inside
the hull transducers must be properly bonded and attached to the hull as described in the
section on inside the hull mounting or must be properly installed by the Boat Manufacturer if
the equipment was installed at the boat factory.
4. If all of the above tests resulted in “0.0” remaining in the window, return the unit for repair.
SYMPTOM: Unit not reading properly at high speeds, causing high random numbers at high
RPM’s.
REASON: There are three basic types of installations: inside the hull, through the hull, and
transom mount. Generally, this situation is attributed to the location and installation of the
transducer. A great deal of air is flowing over the face of the transducer and is inhibiting the unit
from receiving the correct bottom reading. Cavitation (locked on bubbles) either on the face of the
transducer of on the under belly of the boat are preventing the unit from displaying the true depth.
HOW TO SOLVE: Refer to the pages in this manual, along with the drawings for your particular
boat on the proper installation technique. If this is a transom mount transducer, it may require that
the transducer be adjusted lower in the bracket so that it extends further under the bottom of the
boat and is allowed a clean flow of water. It could also require that the transducer and/or bracket
be relocated to achieve a clean, smooth flow of water over the face of the transducer.

Page 15
SYMPTOM: Unit smoked.
REASON: A wire from he transducer was accidentally plugged into the Remote Alarm terminal
located next to the power + or - terminals.
HOW TO SOLVE: Return the unit to the factory for repair.
SYMPTOM: Transom mount transducer breaking where the mounting bracket attaches to the
transducer.
REASON: This occurs if the transducer is installed under a fuel overflow vent OR if an adhesive
such as LOCKTITE was used to bond the hardware onto the transducer mounting bracket.
HOW TO SOLVE: The transducer has probably been permanently damaged and is non
repairable. Before installing a replacement transducer, be sure and move the bracket. The
adhesive or petrol has eaten into the plastic and cannot be repaired.
SYMPTOM: A30 or A03 reads out permanently on the display.
REASON: The only way this could occur is if a lug from a transducer wire was accidentally
connected to either the Alarm Up/Down terminal and power was applied.
HOW TO SOLVE: Unfortunately, permanent damage has been done to the main surface mount
“chip”. The instrument head only must be returned for repair.
SYMPTOM: Unit showing “88.8” in the window.
REASON: This failure indicates a logic circuit failure that was probably caused by a poor solder
connection, lack of solder or improper wiring.
HOW TO SOLVE: Return the unit to the factory for repair.
TROUBLESHOOTING:
SHALLOW WATER SENSITIVITY
The Shallow Water Sensitivity controls a circuit in the depth sounder that effects the first 10 ft. of
water. It alters the system’s response time in this area only and can be used to compensate for
installation imperfections.
For example:
SHALLOW READINGS: If your instrument occasionally displays random, false shallow readings
such as 3.1, 2.8, and 4.3, you may need to adjust this control.
DEEPER READINGS: If your unit is reading false echoes which are deeper than the actual depth,
you may not have enough sensitivity which can also be corrected by using this control.
“O.O” READINGS: Adjusting this control in extremes too far in either direction, could effect your
readings. For example, if the adjustment is made TOO MUCH, it could actually cause the
unit to give a “O.O” reading at a deeper depth. The true depth could be 30 ft. and if the
control is too extreme in a counter clockwise direction, the readout could be “O.O”.
This adjustment fine tunes the installation of your gauge to the location of the transducer on your
boat and to the waters where you do your boating. It is typically an adjustment that made by
the boast owner since it is performed while the boat is in the water.

Each depth gauge is tested at the factory with a transducer located in a water tank and the
Shallow Water Sensitivity is factory pre-set. However, during shipment, after installation or in your
local waterways, it may require that you perform this minor adjustment so that it performs to its
maximum potential on your boat.
With inside the hull transducer installations it is especially important to perform this adjustment, It
is impossible to control the many types of hull configurations on the many varieties of boats
available today. Since fiberglass hulls are generally hand-layed, the hull thickness can vary from
boat-to-boat even though they may be the same model. Thickness of the fiberglass, combined
with the many types of bottom conditions )sandy, rocky, muddy), can affect the readings on your
digital depth sounder. This control enables you to more precisely tune your gauge so that the unit
reads properly. Unless major changes take place in your boating environment, you should not
need to adjust this setting again.
WHEN TO USE LESS SENSITIVITY SHALLOW READINGS:
When your instrument displays a series of random, shallow readings (3.5, 2.9, 4.1) when the
actual depth is greater.
HOW TO PERFORM: When looking at the rear of the instrument, this adjustment is make in a
clockwise direction. (This control operates much like the volume control on a radio. If you turn it all
the way down, you cannot hear the music. Turning it up too far, makes the music blare and sound
out of tune.) Turning the sensitivity control too much can actually “squelch” out the transmit pulses
and the return echoes and will result in a “0.0” reading in the display window. NOTE: When
making this adjustment, turn the control no more than 1/16th of a turn at a time and then wait 3 to
4 seconds before making the next adjustment turn.
WHEN TO USE MORE SENSITIVITY DOUBLE ECHOES READINGS TOO DEEP:
When your instrument is displaying depths that are actually greater than the actual depth. For
example, if your are in 6 ft. water and you turn this control too far in the less sensitivity direction,
you may see “12.0” appear in the LCD window. This is very dangerous since you will actually be
operating the boat in shallower water than that which is displayed. Caution should be exercised to
locate the Sensitivity Control somewhere between both ends of the rotation.
HOW TO PERFORM: By rotating the control in a counter-clockwise direction (when looking at the
rear of the instrument), you can increase the sensitivity of the gauge to the first 10 ft. water.
Increasing this adjustment too much in the MORE SENSITIVITY direction can cause a “doubling”
of the actual depth. NOTE: When making this adjustment, turn the control no more than 1/16th of
a turn at a time and then wait 3 to 4 seconds before making the next adjustment.
