Just the normal summer color for most mid-west lakes. It's clear but not like tap water.
I think the unit is capable of much better pics in 2d. I just messed with it for a few minutes one day. With the original settings the screen was way too cluttered. I think Black and white units are way easier to set up with 2d. Only 1 thing to consider, is my pic clear? With color, there's too many buttons. I need to retire so I can figure this thing out. LOL
