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.
