I recently found my primary depth sounder has gone TU. I strongly suspect it's the unit and not the transducer. It'll be a while before I plan to haul the boat so a new system now is not in the plans. A shoot-thru-the-hull system would be a possible solution, but I'd rather avoid the expense at this time. I still have an operating fishfinder at the helm for depth displays.
To avoid additional short term expense and simplify returning the system to service, I'm looking for a used Standard Horizon DS-2 unit like this. If anyone has one sitting around the garage that they'd like to get rid of, I'd sure be interested.
