I'd end up shooting the grappling hook up over something, but since I've sort of let myself go, I'd just have a rope haning off a wall. For me, I'd say it'd be good for an "Instant Rope Swing", but that's about it. No Batman moves for me....
I guess if you're out of ammo, a whack in the head with a 50 pound quad hook wouldn't be to comfortable. At least it'll buy you some time to reload your magazine.
With my luck, I'd get the hook stuck everytime I shot it......You would drive by my house and see 27 hooks stuck up in the trees with a short piece of rope attached.......
we have one very simular to that at work but it fires a personal floatation device attached to a rope. takes up to 3000 lbs of compressed air to fire 75 yds. we pulled it out to train on it the other day i wasnt impressed with its performance
