I have an old Horizon Standard Depth Sounder
, model DS-1 that finally stopped working after water
got into the display. Looking to possibly replace with a unit that can use the through-hull transducer that I am guessing, not sure though, came with it originally. Has anyone had any luck with a replacement for this unit utilizing the old transducer? There are quite a few boats in my marina still using the HS sounder, so I am assuming these were popular back in the day. Thanks...
