Hi George
I have one you could buy off me. Funny enough, the transducer bracket snapped and not got round to replacing. My daughter goes to Gloucestequite often so could be an easy transaction - at a safe Covid distance of course!
I have one I don’t need anymore I’ve just replaced it with a new one so I have the bracket as well if you still need it or would like a spare? It does work I just wanted a map on the same system so I replaced it.
