INSTALLA TION
TOOLS AND HARD WARE YOU WILL NEED
Screwdriver
Four #10 screws with flat washers or up to 1/4" scre ws (to attach gimbal
bracket to dash)
Hand-held drill with a 5/32" drill bit
Marine grade caulking compound
TRANSDUCER INST ALLATION:
The HS-3D4 supplied with your X-70A 3D is a 384 kHz, 4 element, highspeed, transom mount transducer . It can be installed on any outboard or
stern-drive (inboard-outboard) powered boat. The built-in “kick-up” brac ket
helps prevent damage if the tr ansducer strikes an object while the boat is
moving. If the transducer does “kick-up”, it can be pushed back in place
without tools.
Read this section carefully before attempting the installation. Determine
the best mounting location for your boat. Remember , the transducer location is the most critical part of a sonar installation. If it isn’t done properly ,
the sonar can’t perform to it’s designed potential.
1
T ransducer Location
1. The transducer must be placed in a location that has a smooth flow of
water at all times. If the transducer is not placed in a smooth flow of
water , interference will sho w on the sonar’s display in the form of random lines or dots whenever the boat is moving and can completely
mask the sonar image at high speed.
2. The transducer should be installed with its face pointing straight down,
if possible.
3. Make certain the chosen location doesn’t interfere with the boat’s trailer .
Also, don’t mount it closer than about one f oot from the engine’ s lower
unit. This will prevent cavitation interference with the propeller. Typically, the transducer should be mounted as far down on the transom
as possible. This increases the chance that it will remain in the water
at high speed or sharp turns, and reduces the possibility of air bubble
interference (cavitation).
4. Don’t mount the transducer directly behind strakes or ribs on the bottom of the hull. Typically, a good location on aluminum boats is between the ribs closest to the engine. The port (left) side of the transom
is preferred for mounting the transducer, however, if this is not possible, the starboard (right) side can be used, usually with good results.
CLAMP THE TRANSDUCER CABLE TO
TRANSOM NEAR THE TRANSDUCER. THIS
WILL HELP PREVENT THE TRANSDUCER
FROM ENTERING THE BOAT IF IT IS
KNOCKED OFF AT HIGH SPEED.

T ransducer Assembl y and Mounting
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 mov e the transducer so that it’s parallel with the ground.
1. Press the two small plastic ratchets into the sides of the metal brack et
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.
DOT
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 brack et. Place the ratchets 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 it does, 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.

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.

the mounting holes. Drill two 5/32" holes in the marked locations for
the #10 screws supplied with the transducer .

SIDE VIEW
5. 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. If possible, route the
transducer cable away from other wiring on the boat. Electrical noise
from the engine’s wiring, bilge pumps, VHF radio wires and cables,
and aerators can be picked up b y 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. Do not allow the transducer bracket to go belo w the bottom of the hull!
SONAR UNIT MOUNTING
Install the X-70A 3D in any convenient location, provided there is clearance behind the unit when it is tilted for the best viewing angle. Holes in
the bracket base allow wood screw or through-bolt mounting. Make certain there is enough room behind the unit to attach the power and transducer cables.
Using the bracket as a template, mark the dash for the mounting holes,
then make a mark in the center of the bracket location f or the cab le hole.
If you want the smallest possible hole f or the power and transducer cab les
in the dash, install the transducer first, then route the cable to the desired
location. The smallest hole that will pass one power or transducer plug is
5/8". After the hole is drilled, pass the transducer connector up through
the hole first, then pass the power cable do wn through it.
After routing the cables, fill the hole with a good marine sealing compound. Place the br ac ket over the hole and route the cables through the
slot in the back of the bracket. Break out one of the other slots for the
transducer cable. Screw the bracket to the dash.

POWER CONNECTIONS
The X-70A 3D works from a twelve-volt battery system. For the best results, attach the power cable directly to the battery. You can attach the
power cable to an accessory or power b uss, howe ver you ma y have problems with electrical interference. Therefore, it’s safer to go ahead and
attach the power cable directly to the battery . If the cable isn’t long enough
to reach the battery, splice #18 gauge wire onto it. The power cable has
two wires, which are red and blac k. Red is the positiv e lead, black is negative or ground. Make cer tain to attach the in-line fuse holder to the red
lead as close to the power source as possible . F or example, if y ou have to
extend the power cable to the batter y or power buss, attach one end of
the fuse holder directly to the battery or power buss. This will protect both
the unit and the power cable in the e vent a short occurs.
IMPORTANT!
Do not use this product without a 3-amp fuse wired into the power cable!
Failure to use a 3-amp fuse will v oid y our w arranty.
If you’ve purchased the optional ST-T speed/temperature sensor , install it
according to the instructions included with the sensor. Route its cable to
the X-70A 3D’s po wer cable and plug it into the connector marked “SPEED/
TEMP CABLE”.

DISPLAY - General
When the X-70A 3D is first turned on, the display looks similar to the one
below . The 3D screen scrolls from right to left, with the scale on the right
side of the screen. The current depth beneath the transducer shows in
the upper right corner of the display . A fish symbol to the left of the depth
shows that the Fish ID feature is on. The word “AUTO” signifies that the
automatic function is on, keeping the bottom on the display at all times. If
the computer identifies targets as fish, one of four fish symbols appear on
the screen, depending on the size of the target. Numbers above the fish
symbol tell you the depth of the target. This feature is called “FishTrac k”.
The lights are on for a few seconds when the X-70A 3D is turned on.
Menus appear at the same time. To leave the lights on, press the ON k ey.
This key controls the back lights . If you don’t want the lights on, w ait a fe w
seconds and they will automatically turn themselves off. The menus will
also disappear after a few seconds, or you can press the CLEAR key to
erase them.
The Metric and Display menu labels work the same way. Press the key
adjacent to the Metric label to change the depth from feet to meters. This
also changes the temperature display to degrees Celsius, speed to knots ,
and log to kilometers.
The Display menu on the screen's right side lets you adjust the displa y’s
for the best contrast. Press the left arrow key to decrease the contrast,
right arrow key to increase it.
The X-70A 3D automatically detects the speed/temperature sensor . If the
sensor is attached to the unit, speed, temperature, and distance log automatically appear on the display. Distance markers also appear on the
8
screen, showing the distance behind the boat. If the speed/temperature
sensor is not plugged into the X-70A 3D , then none of these will show.
MODES OF OPERATION
The X-70A 3D shows a sonar picture of the underwater world in 3D, 2D,
Bottom Depth View, and FasTrack™ modes. The 2D and Bottom Depth
Views can use either the 384
or 192 kHz transducer (if the
optional 192 kHz transducer is
attached). The 3D mode is always 384 kHz. To switch between the different modes, first
press the WINDOWS key.
Press a key on the left side of
the screen to choose the desired mode. Press the CLR
key to e xit this men u.
In the 3D mode shown at right,
the bottom is represented by a “wire-fr ame” model. Only the bottom and
fish symbols show in this mode. Structure, weeds, thermoclines, etc. will
not show .
The X-70A 3D uses a 384 kHz transducer with four elements. The digital
depth display shows the bottom depth from the middle transducer elements. If it loses the signal from any element, a bo x with the word “LOST”
appears over the corresponding area on the displa y. This means the unit
cannot receive an echo from that element. This could be due to a large
drop-off, noise or other natural phenomenon.
The 2D mode looks like a conventional sonar display as shown below.
The bottom echo scrolls from right to left. The range displays on the right
side of the screen. The digital
bottom depth shows in the
upper left corner. When the X70A 3D is put into the 2D 384
kHz mode, the two center
transducer elements are in
use. The two outer elements
are turned off. You can select
the elements from a menu discussed in a later section. The
2D 192 kHz transducer has
only one element.

All 2D modes show the bottom signal, structure, thermoclines, fish (both
with and without the Fish ID feature), baitfish schools, and more. The 3D
view shows a 3D representation of the bottom, with Fish ID symbols only.
The 2D mode shows more information, the 3D mode makes it easier to
visualize the bottom contour .
The Bottom Depth View as
shown at right displays the
depth at the top of the display
in large digits. The graph
scrolls at high speed. Note that
this graph only shows the bottom signal. No structure, fish
signals, or other echoes show
on this display. This feature is
available using either frequency transducer. (384 Bottom or 192 Bottom)
The 3D FasTrak screen converts echoes from all four
transducer elements into short
horizontal lines. Typically, the
thicker the bar, the stronger
the echo. This screen is updated rapidly, giving you
flasher-like performance. You
can view echoes from any or
all elements on this screen.
DIGIT AL BOX
A box containing the digital
displays appears in the upper
left corner of the display when
a 2D display is enabled. You
can switch the size of the display from normal to large by
pressing the FULL CHART
key or by pressing the up or
down arrow ke ys on the selection menu.

OPERATION
The Automatic and Sensitivity features used on the X-70A 3D are the
same for all modes of operation. This section will explain these f eatures .
For information on f eatures specific to different modes , see the 2D or 3D
operation sections.
AU TOMATIC
The X-70A 3D adjusts the sensitivity and range to keep a
detailed bottom signal on the
display when the automatic
feature is on. This is enabled
when the unit is first turned on.
You can turn this feature off to
gain greater control over the
adjustments and features of
this unit.
To turn automatic off, press the AUTO key. A screen similar to the one
above appears. Now press the AUTO key again. This moves the check
mark from the “A UTO” box to “MAN”. Press the CLR (clear) key to erase
the menu. To switch bac k to manual, repeat the above steps , but move the
check mark to the “AUTO” box using the AUTO key.
SENSITIVITY
The sensitivity control adjusts
the receiver’s ability to show
echoes. If it’s adjusted properly , the sonar unit sho ws not
only the bottom, but targets
(such as fish) with little or no
noise. If the sensitivity is
turned too low, no fish signals
will show , and you will lose the
bottom signal in fairly shallow
water .
When the X-70A 3D is in the automatic mode, the computer inside adjusts the sensitivity for the best setting. You can override this setting, adding or subtracting the amount of sensitivity the computer uses. You can
also take complete control of the sensitivity level when the unit is in the
manual mode.
11
To adjust the sensitivity, press the SENS key. A menu appears on the
right side of the screen as shown on the previous page. Press the right
arrow key to increase it, the left arro w ke y to decrease it. When you have
it changed to the desired level, press the CLR key to erase the menu or
wait a fe w seconds f or it to automatically clear.
3D OPERATION
When the X-70A 3D is in the 3D mode, the Fish ID feature is always on
(unless you turn it off). FishTrack (the depth n umbers above the fish symbols) shows you the depth of the fish symbol and can be turned off, if
desired. See the FishTrack section in this man ual f or more information.
3D RANGE
The range is set by the unit as long as it’ s in the auto mode. How ev er, y ou
can adjust the range slightly when automatic is on. The unit won’t let y ou
move the bottom off the screen, and it will correct the range once the
bottom begins to go off the screen. When the unit is in the manual mode,
you can set the range to any that’s available.
T o change the range on the X70A 3D , first press the RANGE
key . A screen similar to the one
at right appears. Simply press
the down arrow key to increase the range or the up arrow key to decrease it. When
the desired range is chosen,
wait a few seconds and the
menu will automatically disappear from the screen or press
the CLR key to er ase it.
The X-70A 3D uses the following ranges: 0 - 5, 10, 20, 40, 60, 80, 100,
150, 200, 300, 400, 500, 700, and 900 feet.
3D ZOOM
The zoom feature enlarges all echoes on the screen, making them easier
to see. This feature works in automatic or the manual mode. (Note: If the
unit is in the 3D automatic mode and the zoom feature is turned on, the
unit will not change the range to a shallower setting. If the bottom signal
goes shallower than the zoom range , the X-70A 3D will simply show a flat
bottom signal at the shallowest range shown on the displa y . F or example,
if you have a zoom range from 45 to 60 feet, and the bottom rises to 30
