Ok have a deal going on on yet another upgrade. So for 7 days I will have a brand new never mounted 777C2 available. This one will come with the optional Quadrabeam transducer which is an upgrade over the standard transducer that normally comes with it. It will also come with a GPS unit which is also an upgrade for this unit. The buyer may choose between a trolling motor mount transducer or a transom mount. The display is a 5inch 256 color screen, with a 640V X 480 resolution. The upgrade transducer is the 200hz/83hz/455 hz Quadrabeam plus. What this does is when you are fishing in say 25 foot of water it scan a 50 foot wide beam. Your coverage will run 2X your depth. 60 foot of water is the limit. The Quadrabeam is kinda like the little brother of the side imaging technology and is displayed on the screen in the same manner. First $475.00 takes this . Price is firm and if not sold will be installed on my boat for upcoming season. My deal partner agreed to wait. His 3000.00 deal is going to decide my 1000.00 deal if I sell this. Thats why the time frame. My location is northeast ohio , near Berlin Lake.
