Loosely attach the transducer to the transom
of your boat with the four #8 self tapping screws
supplied. Adjust the brackets until the desired
height is achieved and snug up the screws.
The flat surface on the transducer should be
as parallel with the water surface as possible, but
tipped forward just enough to keep water pressure
on the flat surface when the boat is moving and
should be 1/16" to 1/8" below the hull of the boat.
Tighten up the bolts.
Remove the #8 self tapping screws one at a
time and fill the hole with silicone caulk.
Failure to
do so may seriously damage your boat!
Reinsert each screw and tighten.
NOTE:
On aluminum boats it may be necessary to
use a wooden backing plate between the transom
and the brackets. Attach a 7" piece of 1 x 6
hardwood flush with the bottom of the hull, and
attach the transducer per the above instructions.
Be sure to varnish the wood and silicone the
screw holes thoroughly to prevent leakage and
damage to your boat.
Cable Routing
After mounting the transducer, route the
transducer cable to your Digi-Troll IV. Be sure not
to damage the cable jacket. Keep the cable away
from ignition, tachometer, alternator and other
electrical wiring to prevent interference. Do not cut
or shorten the cable. Coil the excess and secure it
in place.
Connector removal or cable splicing
voids the transducer warranty.
Connect the transducer to your Digi-Troll IV
(see figure below) and be sure to configure it as a
MASTER unit (see section on Digi-Troll IV keypad
- ON/OFF).
Installing the Optional Transducer
Proper transducer installation is critical to the
performance of your Digi-Troll IV’s depth tracking
features. For best results, follow all mounting
instructions carefully.
Where to Mount the Transducer
Any location along the bottom edge of the
transom is acceptable. The preferred mounting
position is within the center 1/3 of the transom
excluding the area directly in line with the
boat’s propeller.
The transducer must be
mounted where the water is smooth and free of
bubbles. It may be helpful to drive your boat at a
variety of speeds and observe where the water
flows most smoothly off the transom before
deciding on a mounting location. The sonar
signals cannot travel through either open air or
turbulent water, therefore, you must make sure
that the transducer is in intimate contact with
undisturbed water at all times.
If you have an aluminum boat, avoid placing
the transducer behind a row of rivets. The rivets
will cause turbulence and air bubbles. Water
turbulence is minimized when the transducer face
is mounted below the bottom of your boat.
In certain applications for non-metallic hulled
boats, the transducer can be positioned in the
bilge with the bottom surface of the transducer as
level as possible. Make sure that the transducer is
submerged at least 2 inches at all times.
How to Mount the Transducer
To mount the transducer, you will need:
A
slotted
screwdriver
A
phillips
screwdriver
Drill with a No. 28 or 9/64" bit
3/8" wrench
Silicone caulk
Follow the mounting instructions supplied with
your transducer mounting hardware. Attach the
transducer to the brackets and tighten the bolts
just enough to hold it in place. Using the brackets
as a guide, mark and drill the four mounting screw
holes 1/2" to 5/8" deep, using the No. 28 or 9/64"
drill.
