With the introduction of the compound bow in the 1960s, archery practitioners were able to experience a great leap forward in archery practice, due to the ease provided by the bow pulleys during the production of pull effort.

But there was still a gap to be filled, which was the release of the rope, often hampered by discomfort in the archer's fingers, mitigated by the use of protections such as finger tabs or special gloves. But the inaccuracy in shooting continued, even with these accessories.

That's when in the mid-1970s, Mr. Mel Stanislawsky began to produce the first mechanical shooters for archery. A water divider for increased shooting accuracy.

​

The most common triggers available on the market can be divided into four groups:

- Thumb Release (finger trigger)

- Wrist Release (wrist trigger)

- Back tension or Hinge Release (trigger triggered by the rotation of the scapula)

- Resistance Release (resistance trigger)

​

Thumb Release type triggers are held by 2, 3 or 4 fingers: index, middle, ring and little finger, and are operated by the thumb. In this type of trigger the trigger button can be positioned according to the archer's preference, and has sensitivity adjustment.

​

Wrist Release-type models are attached to the archer's wrist and are typically fired by the index finger. These are preferred by hunters.

​

The "Hinge" type triggers are similar to the Thumb Release type. In these the shooting always happens by surprise. Important factor for a shot without the interference of the archer, which could hinder the accurate path of the arrow to the target. In surprise shooting, the archer sustains the bow focusing on the aiming process on the target, while maintaining the contraction of the scapula muscles (rhomboid), thus producing the rotation in the trigger necessary for the release of the string.

​

Triggers of type Resistance are also similar to the Thumb and Hinge models, but the shooting concept is more similar to the Hinge, as the proposal is a surprise shot. Its activation is performed when the bowstring retention force reaches a power programmed by the archer. In this way, during the pull, the archer must block the trigger operation by a button next to the thumb, and after reaching the full pull, the button is released, thus allowing the shooting process that happens only when the pull effort reaches the power to which the trigger was set.

For example: in a 60lbs bow, with a let-off of 75% the power at the end of the draw will be 15lbs. In this case the archer can set the trigger to fire with a few pounds more than at rest, such as 18lbs or more. This way he can aim at the target while increasing the pulling effort until reaching 18lbs the bow is fired. 

​

Incorrect use of triggers can lead to the so-called Target Panic. Problem caused most of the time by anxiety to shoot. In these cases the archer tries to aim at the target but is unable to fix the aim in the center, firing prematurely.

​

The Hinge and Resistance triggers are very suitable for those who are suffering from Target Panic, as they force the archer to keep aiming at the target until the shot happens by itself.
