have many of you assigned the user defined regions to your lowrance for on the water usage? I was just checking it out and playing with some different colors and seems awesome....cant wait to take it to the lake. I really like the earthtones for the bottom and bright colors for the fish. Appears to shade to the bottom giving it kinda a 3D look making structure look more realistic and the fish marks 'pop' off the screen and show that seperation off the bottom that is sometimes hard to distinguish.

I tried a few different colors and used them in my Lowrance a few years ago but I prefer blue background and the default white background. If I was color blind I would definitely try to find the right colors that are most visiable to me. Let me know if you find something that works for you on the water.
