TRANSDUCER MOUNTING PROCEDURE
Humminbird’s high-speed transducer is supplied with your LCR. This transducer has been
designed to give good high speed readings on most all boat designs, including aluminum.
Please carefully cons ider the following before installing your transducer.
TRANSDUCER MOUNTING OPTIONS
A. Transom Mount - The Humminbird high speed transducer allows the transducer element to be
mounted below the bottom of the boat hull keeping the transducer out of turbulent water and
insuring good high speed operation. The transducer will absorb the blow of any obstruction
by rotating up out of the metal spring bracket without harming the transducer, or your boat.
The transducer can be re-engaged by simply rotating the trans ducer down and snapping it
back in place. (See Figure A)
B. Inside Hull Mount - The high speed transducer can be mounted inside the hull (without pivot
assembly) using the proper two-part epoxy, such as Humminbird’s epoxy kit. Even though
there is some los s of signal in shooting through the hull, your LCR will perform well with this
type of installation. You cannot shoot through the hull of an aluminum boat.
C. Trolling motor Mount- This type of transducer is not supplied with your LCR. It is designed to
mount on the foot of a trolling motor. You may exchange your un-used high speed
transducer for a trolling motor transducer. Call the Humminbird Customer Service
Department.
D. Bronz Thru-Hull Mount- This transducer is not supplied with your LCR but for an additional
cost you may exchange your un-used high speed transducer for a bronz thru-hull. The bronz
thru-hull transducer has a threaded stem which installs through a hole drilled in the boat hull,
leaving the housing exposed under the boat. This type of installation must be used for many
boats with in-board engines, because there is no suitable location on the transom away from
the noise and turbulence created by the prop. A bronz thru-hull transducer should be installed
by qualified personnel only.
The LCR will operate well at high speeds with a properly mounted transducer. Remember, a
transducer will not work transmitting through air or through air bubbles.
1. TRANSOM MOUNTING PROCEDURE
Step 1.
MOUNTING LOCATION- It is important that the transducer be mounted on the transom where
water flow is in constant contact with the transducer. You may wish to observe the rear of the
boat while it is moving through the water to determine the best mounting location.
Step 2.
BRACKET INSTALLATION (Aluminum Boats)- To install the metal bracket on an aluminum boat
locate the template on the transom between rows of rivets, or ribs that are on the bottom of the
boat. Align the template so that the bottom corner of the template nearest the center of the
transom is on the bottom edge of the transom.
Once the location is determined mark and drill three 7/64” dia.. holes noted on the template.
Attach the metal bracket using three #10 self threading screws supplied. Be sure to align holes in
the center of the
Bracket slots. On some aluminum boats it may be necessary to use a wood back-up plate. It is
important to use a silicone sealant between the screwhead and bracket in order to prevent
leaking. (See Figure C)
Step 2.
BRACKET INSTALLATION (Fiberglass Boats)- If your boat has a stepped transom located
below and under the main transom, the compact transducer design allows mounting in this area.
This mounting location is recommended for good reading at very high speeds. (See Figure D)
To install the metal bracket on a fiberglass boat, locate the template on the transom in the same
manner as for an aluminum boat. (See Figure C)
NOTE: On boats with more than 15 degree deadrise angle it may be necessary to mount the
transducer slightly off parallel with the water level. (S ee Figure E)
Mark and drill the three 9/64” dia. holes as shown on the template. Attach the metal bracket using
the three #10 self threading screws supplied. Be sure to align the holes so that they are centered
vertically in the three slots found in the bracket. It is important to use a silicone sealant between
the screwhead and bracket in order to prevent leaking.
Step 3.
TRANSDUCER PIVOT ASSEMBLY - Assemble the pivot to the transducer main body using the
two ¼”x5/8” allen head screws, two 3/8” tooth washers and two, ¼” square nuts. Make sure the
tooth washers are sandwiched between the transducer main body and the pivot. The square nuts
are trapped inside the pivot and will not rotate as the allen head screws are tightened.
HOWEVER, DO NOT TIGHTEN AT THIS POINT. (See Figure F)
Step 4
TRANSDUCER ASSEMBLY - Insert the transducer assembly into the metal bracket from the
bottom. Push up until the holes in the plastic pivot align with the uppermost holes in the bracket.
Slide the O-ring on to the headed pin and insert it through the two parts. Assemble by screwing
the ¼”x3/8” allen head screw into the end of the pin and tighten. (See Figure G)
Step 5
ANGLE ALLIGHMENT- Set the transducer angle so that it is parallel with the bottom of the boat
hull. Once proper alignment is achieved, tighten the two allen head screws using the 5/32” allen
wrench provided. The screws are visible through the access holes on each side of the metal
bracket. Check to make sure the transducer main body is rigidly fastened to the pivot. (See
Figure H)
Step 6
CHECK POSITION OF TRANSDUCER- At this point, check to see that the bottom of the
transducer is a minimum of ¼” below the bottom of the transom. (However, as noted in STEP 2,
the top of the transducer cannot fall below the bottom of the transom). If it is not, remove the
transducer assembly from the metal bracket by removing the pin installed during STEP 3. Loosen
the metal bracket mounting screws, re-position the bracket utilizing it’s slotted holes, tighten and
re-assemble. It may be necessary to replace the silicone sealant after this adjustment is made.
NOTE: It may be necessary to make several high speed runs to adjust transducer either
UP/DOWN or to re-adjust the angle to achieve optimum results.
Step 7
CABLE CLA MPS- Install cable clamps as necessary by drilling a 1/8” dia. hole for the # 8 screw
supplied.
2. INSIDE HULL MOUNTING PROCEDURE
Warning: In order to achieve proper results with this type installation, it is important that the
transducer be mounted by someone familiar with the use of two part epoxy adhesives. For this
reason, Techsonic Industries, Inc. will not be responsible for any damage due to the mounting of
your transducer in this manner.
NOTE: An Epoxy Kit (Part N. EPK) is available from Humminbird. This Epoxy Kit has been
formulated for Inside Hull Transducer Installation.
1. Select as flat an area as possible near the aft end and center of boat where the hull is thin
and not double. If the bottom has a runner down the center of boat, select an area to one side
of the runner, but as close to the runner as possible.
2. Clean the inside of the boat with lacquer thinner in the area transducer is to be mounted.
Outside of boat in this area should also be cleaned. (Not with lacquer thinner).
3. Put approximately one inch of water in the bottom of the boat.
4. Put transducer in the water. The bottom of the transducer should be in a flat area and should
be in good contact with the bottom of the boat.
5. Operate the LCR with the boat operating at high speed. The transducer may have to be
moved in order to find an area where satisfactory operation is observed.
6. When an area is found that produces satisfactory operation, mark the location of the
transducer.
7. Remove the water and transducer and clean the marked area and the bottom of the
transducer thoroughly.
8. Using the Humminbird Epoxy Kit or equivalent, mix an ample amount of epoxy without
causing it to bubble and pour it in the area the transducer is to be mounted. The puddle
should be larger than the bottom of the transducer.
9. Coat the bottom of the transducer with epoxy, then put it in the center of the puddle and push
down on the transducer while moving it around in a circular motion. This forces out any air
bubbles that may be trapped between the bottom of the transducer and the hull of the boat.
10. Let epoxy cure then the transducer is ready to operate. No water is now required in the
bottom of the boat and gas and oil that is spilled inside of the boat will not degrade
performance as it will if the transducer is placed only in water.
CAUTION: Do not use the silicone seal or any soft adhesive to bond the transducer to the
hull. This will reduce the sensitivity of the unit.
CAUTIONS
1. Occasionally the “eye“ of your transducer may become dirty from storage or from contact with
oils present in boats or marina environments. (Oil will cause the “eye” to lose the intimate
contact with the water which is necessary for efficient operation.) The “eye” may be cleaned
with liquid detergent.
2. Improper installation of the transducer can alter the efficiency and accuracy of the entire
system.
3. If your boat of transducer is out of the water for a period of time, it may take a short period of
time for the transducer to become thoroughly “wetted” when returned to the water. Also, reentry may cause turbulence, which will create air bubbles in the “eye” of the transducer. The
bubbles will disappear in a short time or can be removed by rubbing the transducer “eye” with
your fingers while the transducer is in the water.
4. If your instrument should fail to function, be sure to check all the electrical connections before
removing the transducer or calling a serviceman.
5. Inspect your transducer cable and make sure that it has not been cut or damaged to the point
where it will affect the performance of the transducer. A slight nick or cut, exposing the outer
cable, can be repaired by wrapping with electrical tape. A transducer can be damaged if the
inner cable and outer cable are allowed to make contact. Such a problem can sometimes be
corrected by properly splicing the coaxial cable. This should only be attempted by a qualified
service technician.
6. If your LCR is not working properly and you suspect the problem might be in your transducer,
we would recommend you borrow a unit from a friend and try it on your boat. If the symptoms
are the same, you can almost be certain that the problem is in the transducer.
INSTALLING THE LCR
The LCR should be mounted on a flat, solid surface for maximum stability. The low profile swivel
mount has four holes drilled in the base. It is recommended that all four holes be used.
Position the swivel base and drill four ¼” diameter holes. Note: The LCR hole pattern Is the same
as for all Humminbird flasher units. Use hardware provided to mount this base to the boat.
Next place the gimbal bracket on the swivel base and attach with four small machine screws,
provided.
Place the LCR in the gimbal mount and make certain the rubber washers provided are placed
between the unit and the gimbal bracket Important: Note which side of the gimbal faces forward.
(Slots on gimbal bracket go towards rear). Also, rubber washer must be located between the unit
and the gimbal bracket.
Install the mounting knobs and tighten snugly. The unit can now be swiveled and tilted to any
desired position.
recommended since the unit cannot be rotated.
OTHER MOUNTING OPTIONS
1. The LCR gimbal bracket can also be mounted on the SM-4, quick disconnect swivel mount.
2. The LCR gimbal bracket can also be mounted directly to the dash without the swivel mount,
however, this method is not
INSTALLING THE CABLES
Your LCR comes equipped with Humminbird’s new Angle-Lock power and transducer
connectors. The power connector is identified with the letter P on the back of the plug.
It plugs into the outlet on the back of the unit marked “Power”. The transducer connector is
identified with the letter T and plugs into the outlet on the back of the unit marked “Transducer”.
Note: An adapter (AD-4) is available to allow use of an old waterproof (BNC) transducer with the
LCR, but be sure that the transducer is a 16degree. A 32-degree transducer cannot be used.
A 11/8” hole must be drilled to pull through the transducer connector. After drilling the hole, pull
the transducer connector up through the hole. If you are installing two units, both transducer
connectors can be pulled through this 1 1/8” inch hole. Next, push the power cable wires down
through the hole. A hole cover has been provided which will dress and hold the wires. Install the
hole cover after determining the necessary wire length from the hole.
The power cable has a red lead to the positive (+) post and the black lead to the negative (-) post.
Install a 1 amp fuse between the red cable and positive post of your 12-volt battery.
If a fuse panel is available, we recommend wiring the power cable into the fuse panel. Note: The
LCR must be fused separately from any other accessory.
Your Angle-Lock connectors can only be plugged in one way. Position the connector so the letter
P or T can be read and the 90 degree bend is pointed downward. Push the connector in as far as
it will go. Turn the positive locking ring as far as it will go clockwise until you feel it lock. Locking
ring as far as it will go clockwise until you feel it lock. Your connector is now locked into place.
Note: For easy access to the connectors, simply loosen the mounting knobs and tilt your LCR
forward. The connectors are now in full view and easy to plug or unplug.
WARNING: This device should not be used as a navigation aid to prevent collision, grounding,
boat damage or personal injury. When the boat is moving, submerged objects will not be seen
until they are already under the boat or bottom depths may change too quickly to allow time for
the boat operator to react. Always operate the boat at very slow speeds if you suspect shallow
water or submerged objects.

HUMMINBIRD FEATURES
("Or why your 'Bird outperforms all other brands.')
Gold Plated Contacts - Gold is one of the best conductors of electricity known, and unlike other
metals, it will not corrode. This is why our waterproof flasher units are equipped with gold plated
contact points on both the transducer and power cable connectors.
Completely Waterproof-Tough inner and outer ABS material cases house all flasher units. Sealed
with watertight "0" rings so that rain, humidity, spray (including salt water) or condens ation will not
affect your Humminbird.
Epoxy Based Printed Circuit Boards - We use a tough epoxy filled fiberglass printed circuit board,
built to military specifications. Unlike paper based boards, the epoxy based board will not crack or
break, and will stand up to long term use in rough water.
Positive Noise Reject System - Easily adjustable control knob to eliminate interference and false
signals with the Humminbird positive noise reject system.
High Speed Readings - Clear bottom readings at any speed up to 75 miles per hour can be
achieved providing the transducer has been properly installed.
Super-Bright Thin Line Lamp-Even in bright sunlight, the flasher super-bright thin line lamp gives
detailed readings.
Night Light - Humminbird's patented night light makes for easy night readings. There is no
additional power drain because the digits adjacent to the flash are lighted by the flash itself.
Other Features
Crystal Control Oscillators for better performance and reliability.
Solid State Electronic Circuitry. Microcomputer Controlled. Heavy Duty Motor for better
performance and longer life. Lifetime-Guaranteed Service Policy with three day turnaround and a
one year full warranty.
Transducers- Humminbird builds all our own transducers. The revolutionary new design means
better performance, finer quality and instant pickup. These transducers never require sanding.
THEORY OF OPERATION
Your depth sounder works on the sonar
principle. The control head generates an
electronic signal which is coupled to the
transducer where it is changed to an
ultrasonic signal. This signal travels through
the water until it hits an object or the lake
bottom. The signal is then reflected back to
the transducer, where it is changed back to
an electronic signal.
The control head measures the amount of
time it takes the signal to travel from the
transducer to the reflecting object and back
again. This time is then converted into feet
(since the signal travels at a constant speed approximately 4800 feet per second), and the
number of feet to the object is indicated on
the calibrated dial with the spinning lamp.
The lamp revolves around the dial once for
each 120 foot reading on the 120 foot units
and once for each 60 foot reading on the 60
foot units. Therefore, the motor in the 120
foot unit rotates at 1200 rpm and in the 60
foot unit 2400 rpm. The motor in the Super
Thirty II unit also travels at the speed of 2400
rpm. This is accomplished by the use of an
integrated circuit signal processor which
permits a 30 foot readout to be displayed on
a unit running at the speed of a 60 foot
model.
YOUR TRANSDUCER
The transducer is the transmit/receive "antenna" of your depth sounder. The transducer converts
an electrical signal from your instrument into accoustical energy which is then transmitted through
the "eye" of the transducer into the water. The return signal (echo) excites the "eye" with an
accoustical shock wave and causes the transducer to send an electrical signal back to your
instrument. The "eye" of the transducer is the flat portion that is focused downward into the water.
For maximum efficiency the transducer's "eye" must not be obstructed and it must be in intimate
contact with the water ("wetted'').
It is suggested you keep the face of the transducer clean. This can be done with soap and water.
NOTE: In order for your Humminbird to perform at Its maximum potential, care should be taken to
Install the transducer properly. This Is the most critical part of the Humminbird Installation. Please
read the following sections thoroughly and follow the installation instructions carefully.
TRANSDUCER MOUNTING OPTIONS
A. Transom Mount - The Humminbird high speed transducer allows the transducer element to be
mounted below the bottom of the boat hull keeping the transducer out of turbulent water and
insuring good high speed operation. The transducer will absorb the blow of any obstruction by
rotating up out of the metal spring bracket without harming the transducer, or your boat. The
transducer can be re-engaged by simply rotating the transducer down and snapping it back in
place.
B. Inside Hull Mount - The high speed transducer can be mounted inside the hull (without pivot
assembly) using the proper two-part epoxy, such as Humminbird's epoxy kit. It is important to
carefully follow the mounting procedure in this manual to insure that a proper mounting location is
selected. Improper mounting will result in loss of depth sounder signal. Do not shoot through the
hull of an aluminum boat.
C. Trolling Motor Mount - This type of transducer is not supplied with your unit. It is designed to
mount on the foot of a trolling motor. You may exchange your un-used high speed transducer for
a trolling motor transducer. Call the Humminbird Customer Service Department.
D. Bronze Thru-Hull Mount - This transducer is not supplied with your unit but for an additional
cost you may exchange your un-used high speed tranducer for a bronze thru-hull. The bronze
thruhull transducer has a threaded stem which installs through a hole drilled in the boat hull,
leaving the housing exposed under the boat. This type of installation must be used for many
boats with inboard engines, because there is no suitable location on the transom away from noise
and turbulence created by the prop. A bronze thru-hull transducer should be
installed by qualified personnel only. E. Transducer Exchange - You many exchange your unused transducer for another type, however, some exchanges may require an additional charge.
Please call the Humminbird Customer Service Department TOLL FREE number listed in the front
of the manual. Your unit will operate well at high speeds with a properly mounted transducer.
Remember, a transducer will not work transmitting through air or air bubbles.
CAUTIONS
1. Occassionally the "eye" of your transducer may become dirty from storage or from
contact with oils present in boats or marina environments. (Oil will cause the "eye" to lose
the intimate contact with the water which is necessary for efficient operation.) Th e "eye"
may be cleaned with liquid detergent.
2. Improper installation of the transducer can alter the efficiency and accuracy of the entire

transducer, we would recommend you borrow a unit from a friend and try it on your boat.
If the symptoms are the same, you can almost be assured that the problem is in the
transducer.
TRANSOM MOUNTING PROCEDURE
Step 1
MOUNTING LOCATION - It is important that the transducer be mounted on the transom where
water flow is in constant contact with the transducer. You may wish to observe the rear of the
boat while it is moving through the water to determine the best mounting location.
Step 2 (Aluminum Boats)
BRACKET INSTALLATION To install the metal bracket on an aluminum boat locate the template
on the transom between rows of rivets, or ribs that are on the bottom of the boat. NOTE:
Template is on the last page of the manual. Align the template so that the bottom corner of the
template nearest the center of the transom is on the bottom edge of the transom. (See figure 3.)
Once the location is determined mark and drill three 7/64" dia holes noted on the template. Attach
the metal bracket using three #10 self threading screws supplied. Be sure to align holes in the
center of the bracket slots. On some aluminum boats it may be necessary to use a wood back-up
plate. It is important to use a silicone sealant between the screwhead and bracket in order to
prevent leaking. (See Figure 4).
Step 2 (Fiberglass Boats) BRACKET INSTALLATION - If your boat has a stepped transom
located below and under the main transom, the compact transducer design allows mounting in
this area. This mounting location is recommended for good reading at very high speeds. (See
Figure 5).
To install the metal bracket on a fiberglass boat, locate the template on the transom in the same
manner as for an aluminum boat. (See figure 4). NOTE: On boats with more than 15° deadrise
angle it may be necessary to mount the transducer slightly off parallel with the water level. (See
Figure 6).
Mark and drill the three 9/6," dia holes as shown on the template. Attach the metal bracket using
the three #10 self threading screws supplied. Be sure to align the holes so that they are centered
vertically in the three slots found in the bracket. It is important to use a silicone sealant between
the screwhead and bracket in order to prevent leaking.
Step 3
TRANSDUCER PIVOT ASSEMBLY Assemble the pivot to the transducer main body using the
two 1/4x%" alien head screws, two %," tooth washers and two'/," square nuts. Make sure the
tooth washers are sandwiched between the transducer main body and the pivot. (See Figure 7).
The square nuts are trapped inside the pivot and will not rotate as the alien head screws an;
tightened. HOWEVER, DO NOT TIGHTEN AT THIS POINT (See Figure 7).
CAUTION: DO NOT APPLY LOCTITE® OR SIMILAR LOCKING COMPOUNDS BECAUSE
THEY WILL ATTACK THE PLASTIC.
Step 4
TRANSDUCER ASSEMBLY -Insert the transducer assembly into the metal bracket from the
bottom. Push up until the holes in the plastic pivot align with the uppermost holes in the bracket.
(See Figure 8). Slide the O-ring on to the headed pin and insert it through the two parts.
Assemble by screwing the '/,"x%" alien head screw into the head of the pin and tighten.
Step 5
ANGLE ALIGNMENT - Set the transducer angle so that it is parallel with the bottom of the boat
hull. (See figure 9). Once proper alignment is achieved, tighten the two alien head screws using
the %2" alien wrench provided. The screws are visible through the access holes on each side of
the metal bracket. Check to be sure the transducer main body is rigidly fastened to the pivot.
Step 6
CHECK POSITION OF TRANSDUCER At this point, check to see that the bottom of the
transducer is a minimum of %," below the bottom of the transom.
(However, as noted in STEP 2, the top of the transducer cannot fall below the bottom of the
transom). If it is not, remove the transducer assembly from the metal bracket by removing the pin
installed during STEP 3. (See Figure 8). Loosen the metal bracket mounting screws, reposition
the bracket utilizing it's slotted holes, tighten and reassemble. It may be necessary to replace the
silicone sealant after this adjustment is made.
NOTE: It may be necessary to make several high speed runs to adjust transducer either
UP/DOWN or to readjust the angle to achieve optimum results.
Step 7 CABLE CLAMPS - Install cable clamps as necessary by drilling a %' dia. hole for the #8
screw supplied. Be sure to route the cable to the side of the bracket. The cable can be cut if it is
installed in the center of the bracket. (See Figure 10). FIGURE 10
3. INSIDE HULL MOUNTING PROCEDURE
Warning: In order to achieve proper results with this type installation, it is important that the
transducer be mounted by someone familiar with the use of two part epoxy adhesives. For this
reason, Techsonic Industries, Inc. will not be responsible for any damage due to the mounting of
your transducer in this manner.
IMPORTANT: Be sure to follow steps 3 through 6 to insure that a proper mounting location is
found. Do not epoxy the transducer until this is done. It may not be possible to find a good
mounting location on some boat hulls due to their construction.
1. Select as flat an area as possible near the aft end and center of boat where the hull is thin and
not double. If the bottom has a runner down the center of boat, select an area to one side of the
runner, but as close to the runner as possible.
2. Clean the inside of the boat with lacquer thinner in the area transducer is to be mounted.
Outside of boat in this area should also be cleaned. (Not with lacquer thinner.)
3. Put approximately one inch of water in the bottom of the boat.
4. Put transducer in the water. The bottom of the transducer should be in a flat area and should
be in good contact with the bottom of the boat. 5. Operate the unit with the boat operating at high
speed. The transducer may have to be moved in order to find an area where satisfactory
operation is observed.
6. When an area is found that produces satisfactory operation, mark the location of the
transducer.
7. Remove the water and transducer and clean the marked area and the bottom of the transducer
thoroughly.
8. Using the Humminbird Epoxy Kit mix an ample amount of epoxy without causing it to bubble
and pour it in the area the transducer is to be mounted. The puddle should be larger than the
bottom of the transducer.
9. Coat the bottom of the transducer with epoxy, then put in the center of the puddle and push
down on transducer while moving it around in a circular motion. This forces out any air bubbles
that may be trapped between the bottom of the transducer and the hull of the boat.
10. Let epoxy cure then the transducer is ready to operate. No water is now required in the
bottom of the boat and gas and oil that is spilled inside of the boat will not degrade performance
as it will if the transducer is placed only in water. Caution: Do not use silicone seal or any soft
adhesive to bond the transducer to the hull. This will reduce the sensitivity of the unit.
3. TROLLING MOTOR MOUNTING PROCEDURE
A "Trolling Motor Transducer," is designed to be mounted on the foot of the trolling motor with the
aid of an adjustable clamp, included standard (see below). Your trolling motor transducer will give
an excellent reading with no interference from the electric motor. Some boat manufacturers are
now glassing in a second trans ducer beneath the front deck for thru the hull reading of the
forward mounted depth sounder. This installation also serves a dual purpose in that a fisherman
can run his big motor at idle speed and use his front depth sounder to scan for submerged
stumps or obstacles. Such a practice can often prevent damage to props and lower units of the
big outboard.
MATCHING THE PROPER TRANSDUCER
A 2" diameter transducer is used on all Humminbird flasher units, except the Super Thirty II which
uses a 1" diameter transducer.
The 2" transducer emits a 16 degree cone angle which, we feel, is most efficient for medium to
deep range flasher units. It concentrates the signal on a given target for a better medium to deep
return, thus a better display on the flasher dial.
The 1" transducer used on the Super Thirty II emits a 32 degress cone angle. This wider beam is
used in shallow water since it provides a wider area of coverage.
NOTE: While the 1" transducer is recommended for the Super 3011, some may prefer the
performance of the 2" transducer. Either will work and it may be a matter of personal preference
as to which one is used.
TRANSDUCER SWITCH ASSEMBLIES FOR MODELS TS1-3 AND TS2-3
The Transducer Switch Model TS1-3 comes complete with one switch and one extens ion cable.
This switch allows you to use one Humminbird depth sounder with two transducers and is ideal
when using one transducer mounted on the transom and the other transducer mounted on your
trolling motor.
The transducer switch model TS2-3 comes complete with one switch and two extension cables.
This switch allows you to use two Humminbird Depth Sounders with a single transducer, mounted
anywhere feasible for your application.
NOTE: With switch in this position depth sounder operates from Transducer #2.
We recommend the use of our new Swivel Mount SM-4 (not shown) in conjunction with our TS1-
3.
Mounting Instructions: Drill a %" hole in the desired location and mount switch with extra nut and
washer provided. See illustrations below for correct cable connections.
NOTE: With switch in this position depth sounder #2 operates from the transducer.
INSTALLING THE CABLES
Your unit comes equipped with Humminbird's AngleLockT'" power and transducer connectors.
The power connector is identified with the letter P on the back of the plug. It plugs into the outlet
on the back of the unit marked "Power." The transducer connector is identified with the Letter T
and plugs into the outlet on the back of the unit marked "Transduc er." Note: An adapter (AD-4) is
av ailable to allow use of an old waterproof (BNC) transducer with the new Angle-Lock T"'
connector.
A 1 1/8" hole must be drilled to pull the transducer connector through the dash. After drilling the
hole, pull the transducer connector up through the hole. If you are installing two units, both
transducer connectors can be pulled through this 1'/B inch hole. A hole cover has been provided
which will dress and hold the wires. Install the hole cover after determining the necessary wire
length from the hole.
The power cable has a red lead and a black lead. Connect this cable to a 12-volt DC Power
Source (battery). Attach the red lead to the positive (+) post and the black lead to the negative (-)
post. Install a 2 amp fuse between the red cable and positive post of your 12-volt battery.
If a fuse panel is available, we recommend wiring the power cable into the fuse panel. `Note: The
unit must be fused separately from any other accessory.
Your Angle-LockTm connectors can only be plugged in one way. Position the connector so the
letter P or T can be read and the 90 degree bend is pointed downward. Push the connector in as
far as it will go. Turn the positive locking ring as far as it will go clockwise until you feel it lock.
Your connector is now locked into place.
MOUNTING SCREW INSTRUCTIONS
Important: Always use special flat washers provided with mounting screws when mounting unit to
prevent breaking plastic knob due to overtightening. Washers must be installed as shown above
between gimbal bracket and knob.
IN-DASH UNIT
The first completely waterproof, flush-mount unit on the market. Fits snugly in the dash, is
attractive and virtually theft -proof. Gives same great detail as the original Super Sixty. Operates
from a single, independently mounted on/off switch, with built-in noise suppression.
IN-DASH INSTALLATION INSTRUCTIONS
1. After selecting a location for your unit and control knob, check under the dash for clearance. 2.
Drill a 3.5 inch diameter hole where you have chosen to put your unit. 3. Now slide your unit into
the hole from the front side of the dash. (Note orientation of unit face before completing the
following steps.)
4. Next, slide the mounting bracket over the bottom of the unit (see next page).
5. Install the flat washer, lock washer and nut onto the two bolts and tighten.
NOTE: Do not over tighten the hex nuts as this may cause damage to the unit. Do not apply
Locktite or similar locking compounds to the unit or bracket as this may cause damage to the unit.
6. The OFF-SENS control of your unit requires a 3/e" hole in close proximity of the unit (due to
cable length).
7. After drilling, install the off-sensitivity label by peeling off the back label and placing around the
3/e" hole.
8. On the blushing (threaded portion) of the control there are 2 hex nuts. Adjust one to
accommodate the dash of your boat and the other to tighten. Now slide the black control knob
onto the control shaft.
9. The final step is to connect the control cable and transducer to the unit. You may choose to
mount your In-Dash Sixty in a location other than in the dash. This can be accomplished with the
use of the Humminbird Bow Mount DBID. This bracket for the In-Dash allows the unit to be
mounted on any flush surface such as on the console, bow or casting deck.
GENERAL OPERATIONAL INSTRUCTIONS
The OFF-SENS knob turns the unit on and off. This SENS (sensitivity) control also adjusts the
circuit so the signal returned from the bottom is strong enough to produce a good display on the
dial. If it is set to produce too strong a signal, echoes will appear on the dial at multiples of the
water depth. This, however, should not be objectionable as long as the operator recognizes the
echoes for what they are. The sensitivity control incorporated in this depth sounder is not a linear
control. In other words, the change in sensitivity is very little for the % turn of the knob. The unit is
designed in this manner in order to allow accurate readings in water which is as little as one foot
deep. Because of this, however, it will be necessary to turn the knob to an almost fully clockwise
position in order to obtain proper operation in deeper water. This does not mean that the
sensitivity of the unit is lessened. Boat motors and other electrical devices can send out electrical
noise that may show as erratic flashes on the dial. The NOISE REJECT knob adjusts the control
head so these noise flashes cannot be seen. This knob is turned clockwise to reject noise pulses.
See page 20 for noise reject adjustment instructions.
NOTE: The Humminbird In-Dash Sixty has a noise reject system built in.
NOTE: A large number of modern fishing boats are now equipped with two depth sounders, one
of which is mounted on the console with the transducer positioned near the back. The second unit
is positioned in front with the transducer mounted off the foot of the trolling motor. Occasionally,
when both units are being operated with full gain, there will be a revolving signal flashing around
one or both dials. This is a result of an overlap of signals due to the expanding cone angle of the
transducer (See Figure 11). This same condition will occur when you pull alongside of another
boat with its depth sounder in operation. This signal will not affect the performance of the unit and
can usually be eliminated by reducing the amount of sensitivity. To avo id the possibility of the
intermingling signals, the transducers should be positioned as far apart as possible upon initial
installation.
Refer to illustrations on page 18 as you read the following paragraphs.
OFF-SENS Adjustment
Move the boat out into 5 to 10 feet of water. Shut off the boat motor and any electronic device
that may cause electrical interference. Turn the NOISE REJECT knob fully counterclockwise.
Turn the OFF-SENS knob just past the click. The dial should flash at 0 feet (see indication A).
Turn the knob clockwise as needed to get a good lake bottom flash at the water depth (see
indication B). Turn the knob farther clockwise and echoes will appear (see indication C). As a rule
of thumb, adjust the sensitivity clockwise until you see the second echo (indication C). This will
normally give you good bottom and fish returns.
In order to allow readings in very shallow water (one to five feet) the SENS control has a special
taper which requires that it be turned almost fully clockwise to read depths over 30 to 40 feet.
This in no way means that your unit is not sensitive as it will read depths up to 200 feet. This
control does, however, allow more control of your signal at shallow depths.
NOISE REJECT ADJUSTMENT
NOTE: When the NOISE REJECT knob is turned clockwise, the amount of the reflected signal
may be slightly reduced. Therefore, turn this knob clockwise only as far as needed to reduce
interference. If there is no interference, this knob can be left in the full counterclockwise position.
NOTE: The Humminbird In-Dash Sixty is the only model with a NOISE REJECT system built in.
Start the boat motor and look for a flashing, moving pattern that covers the circumference of the
dial (see indication D). If these flashes cannot be sufficiently reduced by turning the NOISE
REJECT knob clockwise, reposition the transducer and cable away from the motor to obtain a
minimum number of interference flashes. Then turn the NOISE REJECT knob as far clockwise as
is necessary to reduce the interference. If the interference still cannot be sufficiently reduced,
contact the motor manufacturer for information on reducing ignition interference.
HOW TO READ THE DIAL
Objects Under Water A lake bottom is seldom level or uniform,
and objects in the water or on the bottom may also vary in
depth. The dial readings will indicate these varying conditions
accordingly. To distinguish between the dial indicat ions of rocks
and fish, anchor the boat and watch for signals that change. A
changing signal will usually indicate a moving fish.
Pages 23 through 25 show you examples of underwater
conditions and dial readings. Study these drawings for help in
interpreting what you read on the dial.
NOTE: For additional information and illustrations showing the
interpretation of the depth sounder readings, refer to the
"Humminbird Trouble Shooting and Consumer Information
Guide."

OPERATION OF THE SUPER THIRTY 11 IN VERY SHALLOW WATER
The Humminbird Super Thirty II will operate in the same manner as our Super 60 except the unit
with its wide graduations is ideally suited for shallow water applications. This unit measures to 30
feet on the first revolution and will operate satisfactorily in water depths of 100 feet or more. Since
the unit is designed for shallow water, we recommend that it be mounted forward and in
conjunction with a trolling motor mount. In certain areas of the country, such as Florida, where
many bodies of water rarely exceed 30 feet in depth, the Super Thirty II can be successfully used
as a console mount. When operating the Super Thirty II in water deeper than 30 feet, simply
move the selector switch to the 60 foot setting. The range on the first revolution will then be up to
60 feet as shown on the inner dial.
The slightest change in depth can readily be detec ted with the Super Thirty II. We recommend
you start with a minimum amount of gain, and increase it as needed.
If the depth continues past 60 feet, the bottom signal will continue past zero and you will continue
to get an accurate depth reading by adding the additional depth to 60 feet.
OPERATION OF THE SUPER SIXTY AND IN-DASH SIXTY MODELS IN WATER DEEPER
THAN 80 FEET
When operating the Humminbird Super Sixty and the Humminbird In-Dash Sixty depth
sounders in water deeper than 60 feet the flash will continue past zero, and at this point the inside
dial should be read. The inside dial reads up to 120 feet. For depths greater than 120 feet (two
complete turns around the dial) add 120 feet to outer dial reading where the flash stops.
BIRDTRAP
The Birdtrap allows you to make a portable unit of any permanent mount Humminbird Depth
Sounder except the In-Dash.
Follow the installation instructions received with your portable Birdtrap, then refer to the
operational section of this manual for proper use.
Batteries should be the type with the curled up wire tops. They should be placed side by side,
upright in the battery compartment in the front of the Birdtrap. See "BATTERY CONNECTION
DIAGRAM" on page 30 for proper wiring instructions.
60 FOOT-DIAL INDICATIONS FOR VARIOUS DEPTHS
(Add 60 Ft. For Each Complete Turn Of Dial)
SMALL AND LARGE FISH IN DEEP WATER
The Birdtrap is used in the same manner as a permanent mount unit. The transducer may be
mounted using the suction cup as shown in Figure 12 or, if you have a fiberglass boat with a
single hull, the transducer may be paced in a small amount of water in the hull of the boat.
NOTE: The water must be in direct contact with the hull of the boat.
There cannot be any air between the bottom of the transducer and the hull of the boat.
The metal finger (with the yellow tip) is designed to hold the suction cup onto the boat at idle or
slow speeds. DO NOT use this finger as a handle to remove the suction cup. When running at
medium to high speeds you should first take the transducer out of the water because the suction
cup cannot hold at these speeds.
PORTABLE TRANSDUCER ASSEMBLY
Follow illustration instructions.
CAUTION: You should tie down the transducer cable, so that if the suction cup comes loose it will
not allow the transducer to be damaged by the propeller or possibly pull the unit out of the boat.
Humminbird will not be responsible for any damage due to the suction cup becoming loose.
INSTRUCTION DIAGRAM FOR CONNECTING 6 VOLT BATTERIES TO PORTABLE
BIRDTRAP
Use two six volt lantern batteries with spring terminals. Connect as shown above.
BATTERIES
All Models operate from the 12 volt system on your boat or a 12 volt dry cell source. The dry cell
source may be two 6 volt cells connected in series.
Replace or charge the batteries when you notice that the dial motor has slowed down. This
indicates that the battery voltage has fallen below 10 volts and this low voltage will cause the dial
lamp to flash at less than the actual depth.
NOTE; A weak battery will sometimes cause the lamp not to flash even though the motor still
runs.
NOTE: If the lamp on your depth sounder does not flash or flashes intermittently, check your
battery connections. Very often a battery will operate your trolling motor or crank your outboard
motor, but still not have enough voltage to operate the depth sounder. This is due to the fact that
trolling motors and starter motors are current sensitive whereas the depth sounder is voltage
sensitive.
ICE FISHING WITH THE BIRDTRAP
The Birdtrap provides an excellent aid to ice fishermen. The unit will read accurately when placed
on top of the ice provided that a little moisture is formed beneath the transducer.
NOTE: This procedure does not work if an air gap develops between ice and water.
A small amount of water poured on the surface of the ice will provide a suitable puddle in which to
place the transducer. Schools of fish can often be located before drilling holes, thus saving time
and energy on the part of the fisherman.
In extremely cold temperatures, battery life can be extended by placing the Birdtrap inside a
styrofoam insulated chest. A small portable hand warmer placed beneath the unit will also help
conserve the batteries.
HUMMINBIRD TROUBLE SHOOTING GUIDE
Your Humminbird depth sounder is engineered and manufactured with care and precision and is
tested time and time again before leaving our plant. Each unit is backed by a written warranty and
is guaranteed to perform to your satisfaction.
We have found that in many cases, problems arising with the operation of a Humminbird can be
traced back to a minor error in installation or an oversight on the part of the operator.
If you should ever experience any operational problem with your Humminbird, please refer to the
following Trouble Shooting guide. If, after checking the various areas described, you are still
experiencing problems, we would suggest you return your unit to our plant for repair.
NOTE: Please keep this operations manual in a convenient spot, where it is easily accessible.
Also save the original carton your Humminbird came in, in case you should ever need to return it
for service.
Multiple Flashes at Regular Intervals
If the OFF-SENS knob is turned too far clockwise, the signal will bounce back and forth several
times bet ween the bottom and the boat. This will cause flashes at multiples of the depth reading.
CURE: Turn the OFF-SENS knob counterclockwise until you get a good bottom reading.
Unusual Readings
The signal that is reflected back to the transducer from the bottom, or fish, must be strong enough
to produce a good clear flash on the dial. Weak flashes or no flashes at all usually indicate that
the OFF-SENS knob is turned too far counterclockwise, that you are above deep, decayed
vegetation, or that you are in water over 200 feet deep. In the last two cases, the signal would
probably be absorbed by the bottom or never reach it.
If the NOISE REJECT knob is turned up too high, some of the signal may also be lost.
Motor Does Not Turn
Check power cable contacts.
No Light
Reverse wires at the battery.
Motor Turns, No Light
Check voltage input to depth sounder, 10 volts minimum.
HUMMINBIRD TROUBLE SHOOTING GUIDE (continued)
Motor Turns, "0" Lights, No Bottom Reading Turn sensitivity knob full clockwise, noise rejec tion
knob full counterclockwise. Plug and unplug transducer connector"0" reading should increase in
width when transducer is plugged in.
Rub water into the face of the transducer to provide for proper wetting.
Check for cuts in cable.
If transducer is mounted inside boat, refer to page 10.
Cannot Obtain High Speed Reading If transducer is mounted inside boat, refer to page 7. If
transducer is mounted on outside of boat, check to see that transducer is on driver's side and is
flush with the bottom and transom of boat. Tilt back of transducer slightly down to insure
transducer stays in contact with the water during high speed operation.
Be sure transducer is clear of ribs, rivets or other protrusions that may cause air bubbles to pass
under the transducer.
Cannot Obtain Deep Reading If mounted inside boat, be sure transducer is properly installed with
fiberglass or epoxy resin. If transducer is inside the hull and is not bonded to the hull, the area
must be filled with clean water, free of oil.
Be sure transducer is pointing as straight down as possible with boat in the water.
Proper Operation of Depth Sounder Noise rejection control should be at a minimum setting which
will eliminate any electrical noises which are shown as erratic and random flashes on the depth
sounder.
Sensitivity control should be at a maximum setting just creating a double echo on your depth
sounder. Think of the sensitivity control as the volume control on your radio - the deeper the
water, the more control (clockwise) required.
