I have a Signet Depthfinder and it started giving some wrong readings. The mannual gives a checkpoint to check the wiring. I reconnected all the wire connection with new crimps and it started reported good readings. A week later as I went out for a sail, I notice the problem had resurfaced. I'm now puzzled. Do I still have a wiring problem, or is it the transducer, or the unit itself? Looking for those that have been down this patch before.
