200K, 50K (high frequency, low frequency) mode
The sounder uses ultrasonic pulses to detect bottom conditions. The lower the frequency
of the pulse the wider the detection area. Therefore, the 50KHz frequency is useful for
general detection and judging bottom conditions, while the 200KHz frequency is useful
for detailed observation of fish schools.
DUAL frequency mode
This mode provides the 50KHz picture on the left-half of the screen and the 200KHz on
the right half, and is useful for detecting fish schools which have different reflection
characteristics with frequency. For example, a school of tiny fish like minnow returns
stronger echoes on a high frequency compared to a low frequency.
