Use the Truball Sweet Spot Releases to learn Back Tension safely! Pateneted features give you the same amount of travel each time you use the release. Push the thumb lever forward to draw your bow safely and release the thumb lever when you are ready to begin back tension. T.R.U. Ball® proved that they are the leader of the release aid industry when they invented our Sweet Spot - the first release with variable firing positions for the same travel with every shot! The TruBall Sweet Spot is a perfect release for beginners to learn back tension because you don't have to keep the pinky portion of the handle rotated forward while drawing. We have received THREE PATENTS and have patents pending on this revolutionary release aid and look forward to even more innovations! The first of those innovations is our new Sweet Spot II!
