Archery Release: What It Is and the Four Aid Types

An archery release is the moment stored limb energy transfers to the arrow, propelling it toward the target. On compound bows, archers use a mechanical release aid — a hook-and-trigger device — rather than bare fingers, because compound string angles at full draw cause string pinch and horizontal deflection as the string rolls off the finger pads. A release aid creates a single point of contact on the string, reducing deformation and producing a more consistent shot cycle.

The Four Types of Archery Release Aid

Index Finger (Wrist Strap)

A strap loops around the drawing wrist and mechanical jaws clip onto the D-loop. The archer squeezes the index finger slowly to fire — similar to a firearm trigger. Because the load transfers to the wrist rather than the fingers, this style allows long holds without fatigue, making it a practical choice for hunters waiting on game.

Handheld Thumb Button

Held in the string hand with three or four fingers, this release fires when the thumb presses an external trigger button. The handheld design increases face contact at the jawline anchor point, which improves consistency at the target. It is a common choice in competitive release aid shooting.

Hinge (Back Tension)

Often called a back-tension release, the hinge fires when the archer squeezes the shoulder blades together — driving the bow arm away from the release arm — until the rotating head releases the string hook. Because no external trigger is involved, it trains the archer to fire with back muscles rather than anticipating a trigger, reducing flinch.

Resistance Activated

This handheld aid has no external trigger. After hooking to the D-loop and disengaging the safety, the archer pulls into the cam wall until internal resistance is overcome and the release fires. A static hold will not activate it; continuous back engagement is required, reinforcing correct release training archery mechanics.

Shot Execution Notes

Regardless of type, correct execution means the drawing shoulder continues a small, controlled expansion through the shot rather than collapsing or punching. Switching between release types also requires retuning — archery release choice affects where arrow groups land, so bow tuning and sighting must be adjusted accordingly. For recurve and longbow archers, a shooting tab or glove replaces the mechanical release entirely.
