Awesome fish! I'll have to disagree though. I haven't looked at 2d in so long it would look foreign. I have my contrast turned up a lot, but still low enough I can tell the difference between the fish and brush. That is why I like it. With 2d that is much harder and fish id is not something I trust when it's looking through a bunch of limbs with 40 year old technology. Not sure on the birds, but on my garmins about 85 percent contrast is about perfect. Very bright and easy to see.
