Aphers Posted March 19 Report Share Posted March 19 I've been enjoying exploring some shallow inlets in my Spindrift, and wondering if I could add a depth sounder in some way. I feel that the daggerboard is a bit vulnerable to a grounding and in some places the water is not clear enough to see the bottom. I think a simple sounder would make messing about in shallow places much more fun. I don't want to reinvent the wheel so has anybody in here already done this? I can see three options: - a self contained handheld unit, which my crew could operate. I don't think this would work at high speed and doesn't give a continuous reading. Also pretty useless when single handing unless I stop every time I want to check the depth. - a battery operated unit with a transom mounted transducer. These mostly seem to be fish finders. Not sure how well these function as a pure sounder. And how well does a transom mounted transducer cope with the boat's wake? - a proper built in unit with separate power supply. This option might work if I had a small 12v battery aboard to power nav lights as well, but that's starting to sound like a bigger project and potentially a lot of work. Ideally, I'd want to fit the display on the forward bulkhead, but that's not ideal if I use a transom mounted transducer. And I don't think a through-hull transducer would work up in the bow section due to the vee shape. And would it work through plywood anyway?
