Free to a good home, if you collect or pay postage, is a 1999 Humminbird ns25 chart plotter sounder which packed up working but definitively powers up and works in simulator mode. An electronics genius may get it to work again but for a mere mortal I fitted a new one,
Comes complete with flush mount, cable tidy, all cables for sounder, antenna, power and data card and includes a data card for the UK. It also has an antenna and a transducer. Quite like to tidy out my office so let me know if you want it. Will need some wiring because I cut a lot of the cables to get it off the boat quickly.
Reckon the postage will be a fiver or so.
