Sonar chart in regular grayscale mode, left, and in FishReveal mode,
right. Notice how shallow fish formerly hidden in the surface clutter
become visible in FishReveal mode.
NOTE:
Water conditions vary greatly, and that affects sonar performance.
Under certain conditions, FishReveal will show you more fish than
normal grayscale mode, but the reverse will be true in other cir-
cumstances. We suggest you become familiar with both modes so
you can best match your sonar's performance to the current water
conditions.
