For this reason the 200 kHz frequency is ideal for detailed observation of fish schools. The higher the frequency of the ultrasonic signal, the better the resolution. Therefore, the 50 kHz frequency is useful for general detection and judging bottom condition. The lower the frequency of the signal, the wider the detection area. The sounder uses ultrasonic signals to detect bottom conditions.

The screen you chose appears soon thereafter. Rotate the MODE knob again to choose the display mode desired.
