The 20 year old Datamarine depth and speed instruments functioned well enough for me to bring my boat home, after the PO replaced the paddlewheel and transducer for the speed, but they are both getting very tempermental now. I have spent more time than I want to making sure that they had good voltage connections, cables were OK and not corroded etc. so I think I will replace them. I was thinking along the lines of a Garmin 720s Chartplotter with a depth transducer to replace the one in the hull already. I would then have depth from the transducer, and speed and position from the GPS. Anyone have any other ideas on a decent combination that would give me the same functionality?
