Normal sounder display

50 kHz

The sounder uses ultrasonic pulses to detect seabed conditions. The lower the frequency of the pulse, the wider the detection area. Therefore, the 50 kHz frequency is useful for general detection and judging seabed condi- tion.

The higher the frequency of the ultrasonic pulse the better the resolution. Therefore, the 200 kHz frequency is ideal for detailed ob- servation of fish schools.
