• Edit preset names (EDIT NAME softkey).

softkey).

Manual frequency selection
If you select a frequency manually, the fishfinder operates at that
fixed frequency.
The frequency affects readout on the fishfinder display by altering
the penetration of the sonar signal
• Lower frequencies scan a wide area and penetrate water well.
Use these settings if you want a large coverage beneath your
boat or if you are in deep water.
• Higher frequencies (200 Khz) scan a narrow area but produce
more detail, especially at high boat speed. They are most useful
in shallower waters (up to 1000 feet).
Automatic frequency selection
The system will set and adjust the frequency automatically to suit
your transducer and operating conditions.
Screen settings
The Fishfinder setup menu has a number of settings associated with
the appearance of the Fishfinder screen.
