Adjusting the Bracket
For the best performance, direct the soundbeam vertically. The bottom
surface of the transducer should be parallel to the surface of the water.
1. Place the bracket with the transducer at the selected mounting
location to determine if it will need vertical adjustment.
2. To adjust the angle, hold the bracket in two hands close to the
curved spacer and depress the nut with your thumb.
3. Move the lower bracket into the desired position. Do not force the
adjustment. If the bracket is not easily adjustable, loosen the small
screw. If desired, tighten the screw to lock the bracket in position.
Installation
1. Planing hulls —Place the transducer above the bottom of the
transom but below the water line. It must be out of the water when
the boat is traveling at high speed (see Figure 3).
Trolling —Position the bottom of the transducer about 12mm (1/2")
below the bottom of the transom (see Figure 3).
2. Clean the mounting location.
3. Wet the mounting surface and push the suction cup against it.
4. Tie the free end of the safety line to a cleat, eye or any secure place
allowing only a small amount of slack.
5. Route the transducer cable to the echosounder. Allow about 10cm
(4") more slack in the cable than in the safety line. (If the suction
cup accidently comes free, the force will be absorbed by the safety
line and not the transducer cable.)
6. Refer to the echosounder owner’s manual to connect the
transducer to the instrument.
