Single frequency display

Low frequency
The lower the frequency of the ultrasonic sig-
nal, the wider the detection area. Therefore,
the low frequency is useful for general detec-
tion and judging bottom condition.
High frequency
The higher the frequency of the ultrasonic sig-
nal, the better the resolution. For this reason
the high frequency is ideal for detailed obser-
vation of fish schools.
