6.8 Presentation toolbar
The PRESENTATION softkey gives you access to GAIN, VRM (for measuring depth
and distance), frequency view selection, scroll control and power settings. These
settings affect the monitor you are working on.
Adjusting gain and power
Changing the preset gain settings alters the way the fishfinder processes
background noise (also called clutter), and can improve the readout on the monitor.
You can adjust:
• Gain mode (choose from three auto-settings or manual control)
•Color gain
•TVG
• Color threshold
If you change settings for any of these modes (except auto gain), the fishfinder
applies them to all transducer frequencies.
For optimum performance, use the auto settings.
