Neat concept. At least something innovative in the sight catagory for once. But for a retail of $160 I think I'd like some machined aluminum. Gees, it doesn't cost much to mold any kind of plastic. I guess you're paying for the engineering. And some O-rings for weatherproofing wouldn't hurt either.

Battery life shouldn't be an issue. 2032's are cheap and can be bought anywhere. I think the two week period depends on how many dots being projected and at what intesity----and that's continuous use.
