Selecting A Transducer Location - Eagle TriFinder 2 Installation And Operation Instructions Manual

Your BroadView transducer comes packaged with a trolling motor mount
that uses a plastic bracket with an adjustable strap. It also comes with a
bracket for mounting it to the transom of your boat. These are both
"kick-up" mounting brackets. They help prevent damage if the trans-
ducer strikes an object while the boat is moving. If the transducer does
"kick-up," the bracket can easily be pushed back into place without tools.
Read these instructions carefully before attempting the installation.
Determine which of the installation methods is right for your boat.
Remember, the transducer installation is the most critical part
of a sonar installation.
Recommended Tools and supplies
Recommended tools include: two adjustable wrenches, flat-head screw-
driver. If you prefer the option of routing the cable through the tran-
som, you will need a 1" drill bit. The following installation types also
call for these recommended tools and required supplies (supplies are
not included):
Transom installation
Tools include: drill, #29 (0.136") drill bit. Supplies: high quality, marine
grade above- or below-waterline caulking compound.
Trolling motor installation
Tools: none. Supplies: plastic cable ties.

Selecting a Transducer Location

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
caused by bubbles and turbulence will show on the sonar's display in
the form of random lines or dots whenever the boat is moving.
NOTE:
Some aluminum boats with strakes or ribs on the outside of the
hull create large amounts of turbulence at high speed. These boats
typically have large outboard motors capable of propelling the boat
at speeds faster than 35 mph. Typically, a good location on alumi-
num boats is between the ribs closest to the engine.
2. The transducer should be installed with its face pointing straight
down, if possible.
3. If the transducer is mounted on the transom, make sure 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 (bubble) interference with propeller operation.
