Boxer22, you can't beat SI when searching for cover or structure, if you want to spend the extra bucks. You can mark it with a waypoint and then go over it with 2D and DI for a better look. HB have three settings for DI .... narrow, medium, wide ... which equal to 1/3, 1.0, 1.5 times the water column depth. i.e. wide = 15' in 10 FOW, medium = 10', narrow 3.3'.
