Operation Manual

Echosounder
The echosounder function provides a view of the water and bottom beneath your vessel,
allowing you to detect fish and examine the structure of the sea floor.
Except for the NSS evo2 M-versions, all units have built in CHIRP echosounder and
StructureScan. The units may be connected to a variety of transducers.
Ú
Note: StructureScan and CHIRP can not be operated simultaneously on the NSS evo2. If
simultaneous operation is desired, an external module such as the LSS-2, BSM-2 or a second
NSS evo2must be fitted.
