Summary: My unit quit working after four years. I called lowrance about getting it fixed but they wanted 150 bucks so I decided I didn't want to do anything at that time. One year later I decided to have it fixed and Lowarance told me to throw the unit away because of their five year deal.
Very good for 3 years - then expensive paperweight

Summary: Bottom line: Steer clear if you expect a piece of equipment that lasts more than three years. I'd have given this a four-star rating up until a month ago. That's when it passed its third anniversary of use. And stopped finding its location.
