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.

Normal operation (with FishReveal turned off) shows the weakest ech-
oes as black and the strongest 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
accentuated. This can make it hard to distinguish fish signals inside
thermoclines or other cover.

At left FishReveal menu screen. The feature is off and screen is in

normal mode. Right, Fish Reveal is on, in standard mode.

There are two FishReveal modes: standard and inverted. In standard
mode, the weakest echoes are white and the strongest echoes are black.
Echoes in between vary in gray in proportion to their signal strength.
