The receiver amplifies this return signal, or echo, and sends it to the
display, where an image of the object appears on the scrolling sonar
chart. The sonar's microprocessor calculates the time lapse between the
transmitted signal and echo return to determine the distance to the
object. The whole process repeats itself several times each second.
Dual Search Transducer
Your unit is packed with a Dual Search Skimmer Transducer that can
transmit at 83 kHz and 200 kHz.
A new innovation, the 83 kHz frequency offers superior sonar perform-
ance at all depths from very shallow up to 1,000 ft and provides up to
120º of fishfinding coverage.
Preparations
The following shows the recommended sequence for installing the
transducer:
CAUTION:
You should read over this entire installation section before drill-
ing any holes in your vehicle or vessel!
1. Determine the approximate location for the sonar unit, so you can
plan how and where to route the cables for the transducer and power.
This will help you make sure you have enough cable length for the de-
sired configuration.
2. Determine the approximate location for the transducer and its cable
route.
