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 frequency is use-
ful for general 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 frequency is ideal for de-
tailed observation of schools of fish.
