Sonar frequency
The frequency of the sonar determines the width of the sonar beam,
the depth to which the signals will penetrate and the resolution
of the image. Each of the preset operating modes has its own
frequency settings.
The frequencies supported depend upon the DSM and transducer
connected to your system.
• Lower frequencies (e.g. 50 kHz) produce a wide sonar beam
and penetrate the water well. A lower frequency provides a lower
resolution image that may not be as good at detecting small sh.
Use lower frequencies if you require a large coverage beneath
your boat or if you are in deep water.
• Higher frequencies (e.g. 200 kHz) produce narrow beam
and produce a high resolution image. They are most useful in
shallower water (up to 1000 ft) and at higher speeds.
• Auto. When operating in automatic frequency the system will set
and adjust the frequency automatically to suit your transducer
and operating conditions.
Dual operation
For dual frequency operation you can set Frequency 2 for the
required preset operating modes.
