Humminbird 196ci - no battery, but works fine using AC charger. Batteries are available online for under $20. Only what is seen in photos is included, I believe it is complete, but please check this in pictures, as I am not familiar with fish finders. It is mounted inside of the protective case. All serious offers considered! 

The all new Humminbird PiranhaMAX Fishfinder, 196ci includes internal GPS, allowing you to mark waypoints, see your track, view course of ground and get your GPS speed.
