Transducer Installation
There are two different installation methods for your transducer:
Transom Transducer
Trolling Motor Transducer.
Find the section that describes the method of installation you will be using.
NOTE: If the included transducer will not work for your application, you may
exchange it, NEW and UNASSEMBLED, with mounting hardware included, for a
transducer appropriate for your application - often at very little or no charge
depending on the transducer. Call the Humminbird® Customer Resource Center
at 1-800-633-1468 for details and pricing, or visit www.humminbird.com.
NOTE: Due to the wide variety of hulls, only general instructions are presented
in this installation guide. Each boat hull represents a unique set of requirements
that should be evaluated prior to installation. In addition to the hardware
supplied with your transducer, you will need a powered hand drill and various
drill bits, various hand tools, including a ruler or straightedge, a marker or pencil,
safety glasses and dust mask, and marine-grade silicone sealant.
NOTE: Please read all instructions carefully and completely before beginning the
installation process.
NOTE: When drilling holes in fiberglass hulls, it is best to start with a smaller bit
and use progressively larger drill bits to reduce the chance of chipping or flaking
the outer coating.
Transducer Position Motor Position
The Side Imaging transducer has some special requirements
because of its side viewing capabilities:
The Side Imaging transducer must NOT have anything
obstructing the ‘view’ of the side looking beams, i.e.
nothing can be in the line of sight of these beams (not a
hull, motor, or other transducer, etc).
NOTE: You may need to tilt the motor up and out of the way when
using the side looking beams.
In order for the side beams to be displayed accurately, the
transducer must be mounted so that it is looking straight
down in the water when the boat is in the water.
