Low frequency (LF)
The lower the frequency of the ultrasonic pulse the wider the detection area. Thus, the low
frequency is suitable for general search and judging bottom condition.
High frequency (HF)
The higher the frequency of the ultrasonic pulse the better the resolution. Therefore, the high
frequency pulse is useful for detailed observation of fish echoes.
