I use Switchfire Max mode in most water conditions deeper than 10 ft...

Brushpiles really "pop" out on the screen in Switchfire Max mode...

I turn Switchfire on Max mode and then adjust the Sensitivity in the Sonar Express menu to a point that random dots (clutter) start showing in the water column ...

There will be a fairly "thick" line of surface clutter showing but that doesnt affect the brush image in deeper water...in shallower than 10 ft the surface clutter will "merge" with the top of the brush image and make the image unable to descern between the surface clutter and the brush returns...so in less than 10 ft of water I use Switchfire Clear mode...
