Sonic speed value is initially set to 1500 m/s. This setting can be used for most depth
measurements. Adjusting the sonic speed value will affect the depth reading. If you are
unfamiliar with how to set the sonic speed correction for fish detection, please do not change
the initial setting (1500 m / s).

The depth value initially displayed on the screen indicates the depth from the sensor surface to
the seabed. If you want to get the depth from the sea level to the sea floor, you must add the
boat line value displayed on the screen. The user can set the correction value of the water line
according to the actual situation.
