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 thermo- clines – 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.
