JRC JFE-380 - Instruction Manual Download Page 77

The echo of a seabed with abrupt slope is recorded as a lone difficult to see and less 
discriminative, since it tends to accompany with a false echo due to the side lobe and the 
inherent property of directivity. 
In particular, a seabed with abrupt slope and heavily rugged surface provided an echo very 
difficult to display on the recording.
