Gain
The gain settings alter the way the sonar module processes
background noise. 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 control determines the strength above which echoes
are displayed on-screen.
20% Manual Gain Auto Gain 80% Manual Gain
Auto
In Auto mode the sonar module automatically adjusts the gain
setting to suit current conditions.
When connected to a Legacy sonar module or a Traditional
internal sonar module 3 Auto Gain modes are available:
• Cruising (Low)
• Trolling (Med)
• Fishing (Fast)
.
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.
On-screen gain controls
Touch only and HybridTouch multifunction displays have
on-screen gain controls.
