G5 Outdoors G5 Asd Flip Arrow Squaring Device. The ASD uses an old fashion worm-gear system like the rest of G5 Outdoors accessories but instead of using a cuff system like most on the market the ASD uses a magnetic system that wirelessly powers the device and allows you to square your arrow as it flies off the rest. The result is a much faster process of aligning your arrow and getting it squatting perfect every time. Since the system is wireless it doesn't require any sort of set up or special tools to get the job done and it works on just about all sized shafts making it compatible with a wide variety of different expandable shafts like G5 HEVI G5 V line G5 HEVI and G5 V launcher systems. The device is a simple as using a caliper and a spirit level to get you square to the target but that's where the similarity ends. The device stops short of making contact with the shaft and only uses the fulcrum of the shaft to square the arrow. Package Contents: G5 Outdoors G5 Asd Flip Arrow Squaring Device
