I don't see the problem, so long as there's *lots* of practice involved to the muscle memory and control is that good, and a spotter comes along to ensure the taken shot isn't at another stalking hunter.
And that's intended to be for totally blind persons.
I've heard secondhand of a legally blind man taking, and passing with assistance, the CCW course. "Assistance" meaning someone stood behind him and tapped him on the shoulders to give guidance as to where POA was.
