Low and high frequency displays
Low frequency: The sounder uses ultra-
sonic signals to detect bottom conditions.
The lower the frequency of the signal, the
wider the detection area. Therefore, the
50 kHz frequency is useful for general
detection and judging bottom condition.
High frequency: The higher the frequen-
cy of the ultrasonic signal, the better the
resolution. For this reason the 200 kHz
frequency is ideal for detailed observa-
tion of schools of fish.
