FishReveal
When displaying actual sonar returns, the FishReveal feature helps
show fish targets hidden by surface clutter, thermoclines, weed beds
and other cover with 10 levels of gray tones.
The normal mode of operation (with FishReveal turned off) shows the
weakest echoes as black and the strongest echoes in light gray. Since
all weak echoes are black, fish arches show boldly against the white
background. The drawback is that all weak echoes such as thermoclines
are also emphasized. This can make it hard to distinguish fish signals
inside thermoclines or other cover.
In FishReveal mode, the weakest echoes are white and the strongest
echoes are black. Echoes in between vary in gray in proportion to their
signal strength. The Grayline control determines the range for black to
white. Also note that when using FishReveal, we recommend that you
turn off Auto Sensitivity and turn up Sensitivity to near maximum.
