It's all the rage with some coues hunters here. Works as advertised, even allowing for youth hunters to take game at longish distance. Reliable sources swear by it and you really need the heavy manfrotto head. Lock it on a standing or laying animal and then anyone could get behind the gun and pull the trigger, as in youth hunter.

I make no judgements, I would not use one myself or even consider getting one but that's just me.
