Sonar gain
The gain settings alter the way the sonar module processes
background noise (also called clutter). Adjusting the gain settings
can improve the sonar image, however for optimum performance in
most conditions, we recommend that you use the auto settings.
The gain adjusts the return threshold (echo strength) above which
the fishfinder will show an object on the screen.
There are two gain modes:
• Auto
• Manual
Auto
In Auto mode, the sonar module automatically adjusts the gain
setting to suit current conditions. Any adjustments made apply to all
fishfinder windows using that particular frequency.
For Raymarine sonar modules which do not have CHIRP capabilities
there are three Auto modes, each suited to different scenarios:
•
Cruising (Low)
is ideal for viewing fishfinder images with a
minimum of background noise as you are cruising to your fishing
spot. Only the strongest echoes are displayed.
•
Trolling (Medium)
is a slightly higher gain setting that displays
more detail. This is the default mode.
•
Fishing (High)
provides the most detail, but also displays the
most background noise and surface clutter.
Manual
If necessary you can set the gain controls manually, between a
value of 0% to 100%. This value should be set high enough to
see fish and bottom detail but without too much background noise.
Generally a high gain is used in deep and/or clear water; a low gain
in shallow and/or murky water.
The new values remain set even when you switch off the display,
they are applied to both the active window and any other fishfinder
windows with the same frequency.
Selecting the frequency for gain adjustments
When connected to a Raymarine CHIRP sonar module, the gain
for frequency 1 and frequency 2 can be changed independently or
both at the same time. If connected to a non-CHIRP sonar module
adjustments will be made to both frequencies simultaneously.
