Digi-Troll Transducer
By purchasing the optional Digi-Troll transducer accessory (1491072), the Digi-Troll 10 is able to display water
depth and independently bottom track.
Installing the Optional Transducer
Proper transducer installation is critical to the performance of your Digi-Troll’s depth tracking features. For best re-
sults, 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 cen-
ter 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 so-
nar signals cannot travel through either open air or turbulent water, therefore, you must make sure that the trans-
ducer is in 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.
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 seri-
ously damage your boat! Reinsert each screw and tighten.
