Spin Wing Formaster

The Original Formaster Training Aid uses a rubber resistance cord, which allows you to train with the full-release of an arrow.

The Original Formaster is designed with two pieces: the Strap and the Resistance Cord. (Each sold separately for a customized fit)

To determine your size:

• Measure the full circumference around elbow with your draw arm completely straight.
• This measurement should be at the largest part of the elbow.
• The Strap should fit snugly around the draw arm when arm is bent in the full draw position.
• If strap is too large, it will slide down the arm, causing the rubber cord to be too weak to obtain optimal results.

Sizes:

• X-Small (8″-9″)
• Small (6″-10″)
• Medium (10″-11″)
• Large (11″-12″)
• X-Large (12″-13″)
• XX-Large (13″-14″)
