In shallow fishing grounds with hard or rocky bottom, bottom reflections often interfere
with wanted fish echoes and they can not be eliminated sufficiently with the aforemen-
tioned TV and A C functions, especially when the Tilt is set to a larger angle in order
to track schools of fish approaching within
m. In such cases try to reduce the out-
put power by ad usting the Tx power instead of turning down the gain. The picture be-
comes clearer when the output power is reduced rather than when the gain is
decreased as illustrated below.
