The Max Pro 4 gives you all of the accuracy and consistency or a target release with the features that a hardcore hunter demands. This release is completely silent so you will not spook game and features easy open jaws to help you get connected at the moment of truth. The head swivels 360 degrees to eliminate torque and help you be more consistent. The smaller head and jaws on this release allows you for more draw length and greater bow speed (FPS).
