Re: Fish/Depth Finder - Depth and Shallow Water Alarm Settings
I keep mine at 3', too, even though I can go a lot skinnier than that. I'm always searching for the sand bars, but it's the shelf that concerns me as the tide goes out. Having the sailing experience keeps you more cognizant of the shallows I think, or maybe it's paranoid of them. For cruising, and that's what I think you're talking about, I'd double the minimum draw. What I mean is, if you boat draws 18" of water, then I'd set the thing at 3'.
