I would say it depends.I agree with Rod1210 about the swirling wind all day.Me and TreeHunter hunttogether in themountains and the wind is always swirling evenif you get downwind itends up swirling all over the place.I'm gonna be new to(ScnetLok) it this year and I think it will help in our case.If I were to hunt aflat field edge where you could really pin point wind direction I would say it mattersless but in our case I think it will help.We'll see I guess.I hope it does though.
