1.4.1 Single frequency display
Low frequency (50 kHz)
The sounder uses ultrasound pulse signals to
detect bottom conditions. The lower the fre-
quency of the signal, the wider the detection
area. Therefore, the 50 kHz is useful for gen-
eral detection and judging bottom condition.
High frequency (200 kHz)
The higher the frequency of the ultrasound
pulse signal, the better the resolution. For this
reason the 200 kHz is ideal for detailed obser-
vation of schools of fish.
