Typically, shoot-thru-hull installations give excellent high speed opera-

tion and good to excellent depth capability. There is no possibility of

transducer damage from floating objects, as there is with a transom-

mounted transducer. A transducer mounted inside the hull can't be

knocked off when docking or loading on a trailer.
However, the shoot-thru-hull installation does have its drawbacks.

First, 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 lay-up and construction.
Second, the transducer angle cannot be adjusted for the best fish arches

on your sonar display. (This is not an issue for flasher-style sonars.)

Lack of angle adjustment can be particularly troublesome on hulls that

sit with the bow high when at rest or at slow trolling speeds.
Third, a transducer CAN NOT shoot through wood and metal hulls.

Those hulls require either a transom mount or a thru-hull installation.
Fourth, if your Skimmer transducer has a built in temp sensor, it will

only show the temperature of the bilge, not the water surface temp.
Follow the testing procedures listed in the shoot-thru-hull installation

section at the end of this lesson to determine if you can satisfactorily

shoot through the hull.
TRANSOM TRANSDUCER ASSEMBLY AND MOUNTING
The best way to install the transducer is to loosely assemble all of the

parts first, place the transducer's bracket against the transom and see if

you can move the transducer so that it's parallel with the ground.

1. Assembling the bracket. Press the two small plastic ratchets into the

sides of the metal bracket as shown in the following illustration. 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
14

° transom. Most outboard and stern-drive transoms have a 14° angle.
