The 365 Archery Index Quick Disconnect design allows precise alignment of stabilizer spine each and every time you connect and disconnect from bow. With conventional quick disconnects and just screwing on stabilizers an individual needs to be careful to have the stabilizer tightened the same so spine of stabilizer is lined up the same to the bow. Depending on the spine differential around the stabilizer tube it can create different directional torque if lined up different in relationship to the bow, that difference can change impact of grouping on the target. When using the Index Quick disconnect you just replace your stabilizer stud with index stabilizer bracket and put Quick Disconnect piece on your bow. This will allow easy on and off and also precise alignment on and off.
