Remember, the transducer location and installation is the most critical part of a sonar installation.
Recommended Tools and supplies
If you prefer the option of routing the cable through the transom, you will need a 5/8" drill bit.
NOTE:
The following installation types also call for these recommended tools and required supplies that you must provide (supplies listed here are not included):
Transom installation
Tools include: two adjustable wrenches, drill, #29 (0.136") drill bit, flat-
head screwdriver. Supplies: high quality, marine grade above- or below- waterline sealant/adhesive compound.
Trolling motor installations
Tools: two adjustable wrenches,
Shoot-through hull installations
Tools: these will vary depending on your hull's composition. Consult your boat dealer or manufacturer. Other tools are a wooden craft stick or similar tool for stirring and applying epoxy, and a paper plate or piece of cardboard to mix the epoxy on. Supplies: rubbing alcohol, 100 grit sandpaper, specially formulated epoxy adhesive available from LEI (see ordering information on the inside back cover). A sandwich hull also requires polyester resin.
Selecting a Transducer Location
1.The location must be in the water at all times, at all operating speeds.
2.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 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 transom location on aluminum boats is between the ribs closest to the engine.
3.The transducer should be installed with its face pointing straight down, if possible. For
