I am on my second grunt call from A-way Outdoors called the Bowgrunter Plus. It is great!!! I have called in many deer with it, buck and doe. It is easily adjusted and pins to your jacket for handsfree use while at full draw. It is an inhale type call that will not freeze during cold days.It uses a long rubber peep tubing type hose that is connected to the reed itself. And you can't call too looudly with it. It really is mistake proof and that comes from it's inhale design. I have called in deer all year long with it. If you get one you won't be dissapointed with it at all I can assure you of that. I think their website is www.awayhunting.com
