INTRODUCTION
Thank you for purchasing a Lowrance sonar. Your sonar unit is a high
quality unit designed for both professional and novice fishermen. All of our
sonars have an automatic feature that finds and displays the bottom, fish,
structure, and more! All you have to do is press the on key. However, if
you wish to fine tune the unit, all you have to do is press the menu key. This
series of sonar products has powerful features available through easy-touse menus.
To get started with your Lowrance unit, first read the installation section.
This is where it all begins. Improper installation can cause problems down
the road. After you’ve read the instructions, install the unit, then read the
rest of the manual. The more you know about your unit, the better it will
perform for you.

Transducer Installation
Some of the models covered by this manual have a transom-mount
transducer included. The following are installation instructions for this
transducer.
The “kick-up” mounting bracket helps prevent damage if the transducer
strikes an object while the boat is moving. If the transducer does “kickup”, the bracket can easily be pushed back in place without tools.
Read this manual carefully before attempting the installation. Determine
which of the mounting positions is right for your boat. Use extreme care
if mounting the transducer inside the hull, since once it is epoxied into
position, the transducer usually cannot be removed. Remember, the
transducer location is the most critical part of a sonar installation.
Location - General
1. The transducer must be placed in a location that has a smooth flow of
water at all times. If the transducer is to be mounted inside the hull,
then the chosen location must be in the water at all times. If the
transducer is not placed in a smooth flow of water, interference will
show on the sonar’s display in the form of random lines or dots
whenever the boat is moving.
2. The transducer should be installed with it’s face pointing straight
down, if possible.
3. If the transducer is mounted on the transom, make certain it doesn’t
interfere with the trailer or hauling of the boat. Also, don’t mount it
closer than approximately one foot from the engine’s lower unit. This
will prevent cavitation interference with the propeller. Typically, the
transducer should be mounted as deep in the water as possible. This
increases the chance that it will be in the water in high speed and
reduces the possiblity of air bubble interference.
4. If possible, route the transducer cable away from other wiring on the
boat. Electrical noise from engine wiring, bilge pumps, and areators
can be displayed on the sonar’s screen. Use caution when routing
the transducer cable around these wires.

Shoot-thru-hull v.s. Transom Mounting
(X-28 and X-38 Only)
Typically, shoot-thru-hull installations give excellent high speed operation and good to excellent depth capability. There is no possibility of
damage from floating objects. It can't be knocked off when docking or
loading on the trailer.
However, the shoot-thru-hull installation does have its drawbacks. One,
some loss of sensitivity does occur, even on the best hulls. This varies
from hull to hull, even from different installations on the same hull. This
is caused by differences in hull layup and construction. Two, the angle
of the transducer cannot be adjusted for the best fish arches. This can
be a problem on some hulls that sit with the bow high when at rest or at
slow trolling speeds. Follow the procedure listed in the shoot-thru-hull
installation section in this manual to determine if you can satisfactorily
shoot through the hull.
T ransducer Assemb l y and Mounting - All Units
The best way to install this transducer is to loosely assemble all of the
parts first, place the transducer’s brack et against the transom and see if
you can move the tr ansducer so that it’s parallel with the ground.
1. Press the two small plastic ratchets into the sides of the metal brac ket
as shown below. Notice there are letters molded into each ratchet.
Place each ratchet into the bracket with the letter “A” aligned with the
dot stamped into the metal bracket. This position sets the transducer’ s
coarse angle adjustment for a fourteen (14) degree transom. Most
outboard and stern-drive transoms have a f ourteen degree angle.

2. Slide the transducer between the two ratchets. Temporally slide the
bolt though the transducer assembly and hold it against the transom.
Looking at the transducer from the side, check to see if it will adjust so
that its face is parallel to the ground. If it does, then the “A” position is
correct for your hull. If the transducer’ s face isn’t parallel with the g round,
remove the transducer and r atchets from the bracket. Place the r atchets into the holes in the bracket with the letter “B” aligned with the dot
stamped in the bracket. Reassemble the transducer and bracket and
place them against the transom. Again, chec k to see if you can mo v e
the transducer so it’s parallel with the ground. If you can, then go to
step 3. If it doesn’t, repeat step 2, but use a different letter until you can
place the transducer on the transom correctly.
RATCHETS
3. Once you determine the correct position for the ratchets, assemble
the transducer as shown at left. Don't tighten the lock nut at this time.

4. Hold the transducer and bracket assembly against the transom. The
transducer should be roughly parallel to the ground. The bottom of the
transducer bracket should be in line with the bottom of the hull.

5. Remove the transducer from the bracket and re-assemble it with the
cable passing through the bracket over the bolt as shown above. Attach the transducer to the transom. Slide the transducer up or down
until it’s aligned properly on the transom as shown abo ve. Tighten the
bracket’ s mounting screws. Adjust the tr ansducer so that it’s par allel to
the ground and tighten the lock nut until it touches the flat washer , then
add 1/4 turn.
Don’t over tighten the loc k nut!
If you do , the tr ansducer
won’t “kic k-up” if it strikes an object in the water .
6. Route the transducer cable to the sonar unit. Make certain to leave
some slack inthe cable at the transducer as sho wn abov e. If possib le,
route the transducer cable aw ay from other wiring on the boat. Electrical noise from the engine’s wiring, bilge pumps, VHF radio wires and
cables, and aerators can be pic ked up by the sonar . Use caution when
routing the transducer cable around these wires.
IMPORTANT!
Clamp the transducer cable to the transom close to the transducer. This
can prevent the transducer from entering the boat if it is knocked off at
high speed.
7. Make a test run to determine the results. If the bottom is lost at high
speed, or if noise appears on the display, try sliding the transducer
bracket down. This puts the transducer deeper into the water, hopefully below the turbulence causing the noise. Don't allow the transducer bracket to go belo w the bottom of the hull!

2. Slide the adjustable strap supplied with the TMB-S through the slot in
the transducer bracket and wrap it around the trolling motor. Position
the transducer to aim straight down when the motor is in the water.
Tighten the strap securely. Route the transducer cable alongside the
trolling motor shaft. Use plastic ties (not included) to attach the
transducer cable to the trolling motor shaft. Make certain there is
enough slack in the cable for the motor to turn freely. Route the cable
to the sonar unit and the transducer is ready for use.

SHOOT-THRU-HULL
(X-28 and X-38 Only)
The transducer installation inside a fiberglass hull must be in an area
that does not have air bubbles in the resin or separated fiberglass
layers. The sonar signal must pass through solid fiberglass. A successful transducer installation can be made on hulls with flotation materials
(such as plywood, balsa wood, or foam) between layers of fiberglass if
the material is removed from the chosen area. For example, some
manufacturers use a layer of fiberglass, then a core of balsa wood,
finishing with an outer layer of fiberglass. Removing the inner layer of
fiberglass and the balsa wood core exposes the outer layer of fiberglass.
The transducer can then be epoxied directly to the outer layer of fiberglass. After the epoxy cures, the hull is watertight and structurally sound.
Remember, the sonar signal must pass through solid fiberglass. Any air
bubbles in the fiberglass or the epoxy will reduce or eliminate the sonar
signals.
To choose the proper location for thru-hull mounting, anchor the boat in
60 feet of water. Add a little water to the sump of the boat. Plug the

transducer into the sonar unit, turn it on, then hold the transducer over
the side of the boat. Adjust the sensitivity and range controls until a
second bottom echo is seen on the display. (you will need to turn both
automatic and ASP off.) Don’t touch the controls once they’ve been set.
Next, take the transducer out of the water and place it in the water in the
sump of the boat. Observe the sonar signal to see if there is a noticeable decrease in sensitivity. The second bottom signal may disappear
and the bottom signal may decrease in intensity. Move the transducer
around to find the best location. If the sensitivity control has to be
increased greatly to compensate, then the transducer should be
mounted on the outside of the hull. If not, then mark the location that
shot through the hull the best and follow the instructions on the next
pages for a shoot-thru-hull mounting.

Shoot-thru-hull Installation
(X-28 and X-38 Only)
1. Make certain the area is clean, dry, and free of oil or grease, then
sand both the inside surface of the hull and the face of the transducer
with 100 grit sandpaper. The surface of the hull must be flat so the entire
transducer face is in contact with the hull prior to bonding.

SAND THIS SURFACE
2. Follow the instructions on the epoxy package and mix it thoroughly.
Do not mix it too fast, as it will cause bubbles to form in the epoxy.
(NOTE! Use only the epoxies specified on the inside front cover of this
manual! Failure to use one of these epoxies may result in poor sonar
performance!) Apply a small amount on the face of the transducer as
shown above, then spread a small amount onto the sanded area on the
9
hull. Place the transducer into the epoxy, twisting and turning it to force
any air bubbles out from under the transducer face. The face of the
transducer should be parallel with the hull, with a minimum amount of
epoxy between the hull and transducer. After the epoxy dries, route the
cable to the sonar unit.
Fish Arches
If you do not get good fish arches on your display, it could be the
transducer is not parallel with the ground when the boat is at rest in the
water, or at slow trolling speeds. If the arch slopes up, but not back
down, then the front of the transducer is too high and needs to be
lowered. If only the back half the the arch is printed, then the nose of the
transducer is angled too far down and needs to be raised.
