It looks like a really nice tool for what it is, but a recreational fishing instrument it is not. The people who would be using that auger are going to be commercial. Anyone checking safe thicknesses for roads, which could be resorts, possibly DOT or whatever the Canadian version is. It would also be great for leaving markers for said roads. The description lists this auger as good for ice rescue. I have no idea how often trucks need to be winched out of a snow bank, but I'm guessing it isn't very often compared to a simple tow.
I can't imagine why a fisherman would want one. If you maintain your own plowed path way out on a big lake, then maybe it would be handy. If you are on foot, I don't think this would be a good replacement for a spud bar early season, and once it gets thicker who cares. As for the transducer thing, you guys do know you don't need to drill a hole for a transducer to work, right? You just kick away any snow if there is any, drizzle a little water down, and set your transducer on that.
