Hell, I'm not even sure what color adds on a fishfinder.

In today's market, everthing is pretty much DSP and you get much
better definition. Color allows you to "see" a little better if you
will - you can detail debris vs fish for example just by looking at
the size and density as represented by the colors. That's not the
case with grayscale displays.

When I switched, it made a big difference.
