Stanislawski STAN Double Eagle FourFinger. Two years ago, our sister company, Copper John Corp, launched a trigger based release aid for hunters (the Eagle) that offered the control of a trigger with the accuracy and feel of backtension. Since then, our target archery customers regularly suggested that Stanislawski Archery Products offer a double seared version of the concept. A double sear mechanism neutralizes the effect of the bow's poundage on the trigger's stiffness. It allows a consistent amount of pressure to be used to set off the release regardless of a bow's poundage. The multi-finger DoubleEagle handles are configured such that the ring figner is in line with or slightly ahead of the middle finger. If you try to squeeze the trigger too quickly, you will also squeeze with the ring finger causing the handle to rotate back at the same time the middle finger is supposed to move the trigger. Consequently, the trigger does not move enough in relation to the handle to fire the bow. That being the case, backtension is the easiest and most natural way to trigger this release. Since backtension will seem natural, your mind will be free to concentrate on other aspects of the shot. Stanislawski STAN Double Eagle FourFinger.
