Hi there,
I have just upgraded my fish finder to a colour one. I got the same make so I only had to unplug it and plug in the new one. So for sale now is a NAVMAN FISHFINDER 4431. It is in as new condition and works perfectly. The power cable, transducer & cable and all the fittings are brand new and have not been used. It comes complete with instruction and installation manuals, cd and template. It can be surface / flush mounted for permanant fitting or can be mounted on its own swivel and tilt base for easy removal which is also included. You can log onto the NAVMAN website to get the full specifications. I am asking
