About the product

The Original Formaster and Rigid Formaster Training Aids are excellent for the beginner, intermediate or expert archer. They teach proper back tension and follow-through techniques by establishing muscle memory throughout the draw and release. Technical manual and complete instructions are included. Installs on any bow.

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

Straps
To determine your size. Follow the next steps

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.

Strap sizes

Resistance Cord
It is generally recommended that
Juniors and beginners start with 13 – 17 lbs.
Women and young adults – 21 – 28 lbs.
Men – 28 – 31 lbs.
Please note. The maximum recommended pull-weight without shooting an arrow is 50 lbs. Do not use a finger tab with metal backing, it wil cut the rubber tubing. Do not stretch the rubber more than 4 times its length. Sooner or later the rubber cord wil wear out! Keep the device also out the sun while storing!
