I assumed until I swopped my unit with a similar Lowerance sounder belonging to a friend that I either had a problem with the transducer or with my main processing unit. The swopping seemed to eliminate both and your suggestions does seem more than plausible.
Will try to clean the connection plugs although they look OK, and as I plug/unplug the unit in only when I use the boat it's not as though I havent been doing this.
I'll use the bit of WD40 ( the Ribsters friend) for this, unless you think it would be counter productive. Will try to launch over the w/end and will let you know if this helped. Thanks again
