I fish in a portable house, flip up style. prefer to fish for trout, shallow water, 5 feet and in. I had a cabelas underwater camers some years back, LOL,,, never saw a thing on it. Always dark, couldnt focus on anything. Sold it cheap, a bad investment I guess. Im looking to help myself find fish, identify sandy bottoms, aid in the catching of trout.I had an awful year, other than the thought I m doing everything wrong, Im looking to fix one issue at a time.
