SiTex colormax wide 7" gps/chartplotter/fishfinder multifunction display $600
included with the colormax wide unit is a brand new adjustible base station with rubber cover (so you can easily pop off the unit from your boat in a split second for storage)...and the cover plate.
also included is an ES502D sounder module that allows you to attach a thru hull or on hull transducer to this device and have the colormax unit display the sonar data right on the screen with your chartplotter/navigation display. (note that the transducer is not included as it stayed with the boat).
Everything you see in the picture is included (except the towel and the ping pong table).
