The Heavy Medal and Heavy Medal Barebow SOS Units have been designed to simplify and streamline the archer’s stability experience. These units have been developed to mount directly to the bow in order to provide the smallest footprint possible allowing the SOS to be mounted in places that were previously impossible. The Heavy Medal unit is balanced for compound and recurve archery whereas the Barebow version comes with a shorter weight profile to allow the archer to add the maximum amount of weight in the smallest space possible.
The Heavy Medal and Heavy Medal Barebow units both mount directly to 5/16″-24 holes on your bow’s riser or limb pockets via a cap-head mounting bolt that is included with your purchase. Because of the direct mounting option, the user is able to adjust the wire orientation with complete 360 degree freedom. The wire orientation is extremely important and greatly affects the efficiency of the mass-tuned damper. In our testing, we found the best results with the wires positioned in a vertical orientation.
Understanding and Tuning your SOS Heavy Medal
The SOS Heavy Medal is a mass-tuned damper that when positioned properly, is designed to isolate, collect and dissipate unwanted movement from your sight picture. We have tested and developed these wire lengths and attachment locations to provide the most responsive unit possible. The unit is predisposed to have both a stiff and weak axis. What this means is that the archer will want to adjust the axis orientation to help them where they need it most. If you see up and down movement, set your weak axis vertical. If you’re seeing left and right movement, set the weak axis horizontal. If you’re unsure, test each position and see which is best for you! Some archers even utilize two units, one set facing each axis, in order to maximize their stability. The picture below shows the weak axis facing you. For easy use, the weak axis will always be the direction where wire holes are nearest each other on the weight receiver.
Both units are 100% legal for compound, recurve and barebow use in NFAA, ASA, USA Archery and World Archery competition.
