NOTE: If you are trolling, it is best to mount the transducer on the transom of the boat.
1. Mount the transducer so that it points straight down and so that the
transducer itself is submerged in the water (see the illustration
Portable Transducer Mount).
2. Adjust the running angle so that the transducer is parallel to and
below the surface of the water (see the illustration Transducer
Running Angle).
3. Hand-tighten the wing nut so that the transducer will not rotate.
4. Secure the transducer cable in case of
accidental release when the boat is
moving, since a loose transducer can
cause damage to itself, your boat, or
become tangled in the propeller.
Attach the tie-down strap to the
transducer cable around an
immovable object such as a rail or
fitting, as shown in the illustration (see
the illustration Transducer Tie-Down
Strap).
5. When you have finished using the transducer, unplug the transducer
cable from the transducer jumper port on the base, then coil the cable
around the assembly.
