Sonar frequency
The frequency of the sonar determines the width of the sonar
beam and the depth to which the signals will penetrate. Each of
the 4 preset operating modes has its own frequency settings. The
frequency setting is indicated in the status bar.
There are 3 available frequency settings:
• 50 kHz produces a wide sonar beam and penetrates the water
well. It provides a lower resolution image that may not be as good
at detecting small sh. Typically use this if you require a large
coverage beneath your boat or if you are in deep water.
• 200 kHz produces narrow beam of quicker shorter sonar waves.
These produce a high resolution image but do not penetrate the
water as well as the lower frequency. This frequency is most
useful in shallower water (up to 1000 ft).
• Auto. When operating in automatic frequency your DSM
automatically selects the appropriate frequency for your depth,
50 kHz in deep water and 200 kHz in shallower water.
