I have a Humminbird 898c SI unit for sale, paid $1500.00 new.Comes with a SI transducer and power cords.I bought it new in Feb of 2012, and installed it on a skeeter boat I had at the time.I sold the Skeeter in May 2012 to buy a basscat and took the HB 898 off the boat.Its been boxed ever since.I left the HB GPS receiver on the skeeter, so the unit I have doesnt have the GPS puck.Ill sell the unit without the GPS puck for $1100.00, the cost of a new GPS puck from Humminbird is $149.99. (maybe cheaper somewhere else)I have no map cards, but I will throw in a empty SD card.Heres a link for the GPS puck.http://store.humminbird.com/products/629926/AS_GRPNot interested in trades.Only reason Im selling is to help buy a power pole.
