I guess what it all comes down to with tech is where you draw your own personal line, I don't really have an issue with others using it, I don't really see someone choosing to map a lake with a deeper as cheating, in fact I wouldn't really say its cheating to throw out a fishspy on a spot you have found to check what's really down there, however driving a bait boat to a spot you couldn't cast and bait to is a slightly different thing, and maybe using a bait boat to map the lake may be different again, I guess I've decided if you cast it, then it's kind of OK
