This Garmin Fishfinder 250 came on my boat I bought brand new in May 2005. I already had a good Humminbird I liked, and was use to, so I kept it. Its been setting on a shelf collecting dust since June of 05. Can be used with handheld GPS unit, or antenna.(NOT INCLUDED) Comes with every thing you see. Also comes with a never used, still in package speed sensor unit. $160.00 shipped to you. Please PM me with any questions.
