Every time I think something is useless, someone comes up with reasons why it is useful (like mentioned above). If my eyes were bad or I was having problems I wouldn't question it. If I was using it for coon hunting at night, again, good idea.... I wouldn't put it on simply because it is there.

That said, Michigan has a law banning the use of any laser aiming device for hunting applications! Unless, you have dr's orders that you have limited eye sight, or are legally blind and the laser is to aid your hunting partner with helping you aim the weapon.
