7.4 Manual Fish Finder Operation
Use the manual operation to see schools of fish and the bottom echo with a fixed gain
setting.
The gain, range and range shift functions let you select the depth you can see on the
screen. The basic range provides a "window" into the water column and range shift
moves the "window" to the depth that you select.
