4. If the unit is working properly, gradually increase the boat speed to

test high-speed performance. If the unit functions well at low

speeds but begins to skip or miss the bottom at higher speeds, the

transducer requires adjustment. Angling the rear of the transducer

downward and/or lowering the transducer farther into the water

will help achieve depth readings at high speeds. If the left side of

the fish arch is longer than the right side, then the back of the

transducer is angled too far downward. If the right side of the fish

GPS Receiver Installation Overview

To optimize performance of the GPS receiver, mount it in an area that has full exposure to the sky. The effective area of reception is 10° above the horizon. Different circumstances determine the mounting method appropriate for your GPS receiver.

arch is longer than the left side, then the back of the transducer is

angled too far upwards.

NOTE: It may not always be possible to get symmetrical fish arches and high speed depth readings at the same time. Due to the wide variety of boat hulls, however, it is not always possible to obtain high speed depth readings.

NOTE: It is often necessary to make several incremental transducer adjustments before optimum high speed performance is achieved.

Once you have reached a consistently good sonar signal at the desired speeds, you are ready to lock down the transducer settings.

5.Mark the transducer bracket location on the transom with a pencil, then pop up the bracket to reveal the mounting screws. Tighten the stainless steel mounting bracket screws to secure in place. Hand-tighten only!

The pinouts of the pigtail cable are as follows:

Red Wire, +12V (output voltage only)

Black Wire, Ground

White Wire, NMEA Out.

CAUTION! Please use caution before connecting the red +12V wire to any other NMEA device. This is an output voltage provided by the Fishfinder unit and GPS receiver and should only be connected to those NMEA devices that need a 12 volt input.
