On a 7 TI I downloaded fish reveal and went to a lake today and used it off and on for about 5 hrs. Kept my waypoints also as they are all there. To get rid of the clutter, just had to adjust sensitivity alittle and contrast just a notch. Seems to work ok and I like it, but need to use it again and play with settings. Got blowed off the lake by 18 mph winds gusting to 25.
