"Diagnostic" is selected with the sonar mode option of the System menu. It is a special screen
that displays the raw sonar information being received by each of the six sonar beams. Viewing
the information in this manner is helpful when selecting a mounting location for the transducer, or
when troubleshooting potential problems.
If you are selecting a location inside the hull of your boat to mount the Wide 3D Vision transducer,
the diagnostic view lets you compare the individual beam returns while you position the
transducer.
Your boat should be in the water over a flat, level area of bottom. If there are no obstructions or
inconsistencies in the hull at the mounting location, all six beams should be very similar in
appearance. The top of the screen is the surface of the water, and the signal reflected from the
bottom is displayed at the appropriate depth. A weak or irregular signal will be easy to spot, and
moving the transducer slightly may correct the problem.
The Wide 3D Vision transducer is very sensitive to hull irregularities, and care should be taken to
find a location that gives identical returns from each of the six beams.
WIDE SIDE OPERATION
Wide Side is an accessory transducer that gives your
Wide 3D Vision the capability of collecting sonar
information from either side of your boat. Side-looking
sonar is extremely valuable for bank
fishing, or looking for bait fish in open water.
The Wide Side transducer contains 3 different
elements which transmit signals to the left, right, and
straight down from your boat. The downward beam is
200 kHz with a 24 degree area of coverage. This
beam maintains a continuous digital depth readout
from the bottom directly beneath your boat. The side
beams are 455 kHz with a 16 degree area of
coverage. These side-looking elements can be used independently, or together to locate targets
near the surface of the water on either side of your boat.
