Summary: I have always liked Garmin products and have owned a couple of hand held GPS units. They are solidly made and have lasted for years. So when I saw that they made a fish finder I didn't hesitate in getting one for my new fishing boat. I couldn't be happier. It works very well.
Summary: I recieved this Garmin 550c fishfinder and after drilling holes in my boat for the transducer and mounting brackets,and after fishing the wires from the transom to the console plus making the electrical connections, the unit never powered up.
