The T.R.U. Ball® T.R.U.Tension takes technology to a new level. Our T.R.U. Tension releases are the most repeatable in the business (when wrapping the rope around the bowstring) due to our patented and patent pending technology that keeps the hook and the string parallel to each other. The T.R.U. Tension is very economical and is great for a practice release or to help overcome target panic.
