This is off my boat. I am replacing it with a GPS/Fishfinder unit from Frank at Calumet Marine. It's an awesome little unit for Marking Fish, Baitfish, Tracking Cannonball, etc. You can't find a Raymarine Unit or any unit for that matter in color in this price range with these capabilities. I'll take it back for 30 days if it does not work. I know It does because I've been using it this season. $180 Shipped including Tri-Ducer.
