I like new toys but I do not always impress easily. Recently we went fishing with a humminbird fish finder. First of all is was in a watertight mounting that will float. It does not you much good to have a waterproof devise if it is on the bottom. I liked the way it was back lit and yet I could select the background colors for night use. We knew exactly where we were with the built in GPS system and there was a trip log for distance traveled, time underway and our average speed. We just set it on automatic and let it lead us to the fish.
