Understanding Compound Bow Releases

A compound bow is a modern type of bow that uses a levering system, typically made up of cables and pulleys, to bend its limbs. This system gives the user a mechanical advantage, so the limbs of a compound bow are stiffer than those of a traditional bow. This makes the compound bow more energy-efficient and accurate.

A release aid, also known as a mechanical release, is a device that helps to fire arrows more precisely, using a trigger to release the bowstring rather than the archer's fingers. It makes the release of the bowstring quicker and reduces torque on the bowstring from the archer's fingers.

There are four main types of mechanical releases: index finger release, thumb button release, hinge or back tension release, and tension-activated release.

Types of mechanical release

Mechanical releases are an essential component of a compound bow setup. They are devices that aid in releasing the bowstring and are often referred to as "release aids". The market for mechanical releases is diverse, with various types designed to meet different needs and preferences. Here is an overview of some common types of mechanical releases:

Wrist Releases (Finger Trigger):

Wrist releases are the most popular form of mechanical release among hunters. They are attached to the wrist and have a trigger mechanism that is activated by the index finger. Wrist releases typically use either single or dual ball bearing caliper jaws or hook/fang-style jaws that work well with string loop setups. The Tru-Fire Hardcore Max and the Scott Archery Shark are popular choices in this category, known for their adjustability and comfort.

Handheld Releases:

Handheld releases are becoming increasingly popular among hunters. They are not attached to the wrist and are typically T-handle shaped. Handheld releases can be activated by the thumb or back tension. The Tru-Fire Hardcore Revolution is a top choice in this category, offering a wide range of adjustments and a smooth 360-degree rotation.

Hybrid Releases:

Hybrid releases combine the features of wrist and handheld releases. They have a handheld grip but use a finger trigger similar to wrist releases. The Scott Archery Caliper Grip is a well-known hybrid release, offering the convenience of a handheld release with the familiarity of a finger trigger.

Thumb Releases:

Thumb releases are handheld devices that come in three or four-finger configurations. They have a thumb-activated trigger mechanism and are known for their accuracy. The Scott Archery Sigma Release is a highly customisable thumb release with adjustable trigger sensitivity and travel.

Back-Tension/Hinge Releases:

Back-tension or hinge releases are unique in that they have no manual trigger. Instead, they utilise back tension to activate the release. The T.R.U. Ball HBC Quicksilver is a popular choice in this category, known for its customisability and smooth release.

Resistance-Activated Releases:

Resistance-activated releases are handheld designs that operate similarly to back-tension releases but include a safety mechanism. The Stanislawski PerfeX Resistance is an example of this type, offering a wide range of adjustments and a consistent release.

Ultimately, the choice of mechanical release depends on personal preference, comfort, and shooting style. Each type has its own advantages and a loyal following among hunters and archers.

How to attach a mechanical release

To attach a mechanical release to a compound bow, follow these steps:

First, decide which type of mechanical release you want to use. There are four main types: index finger release, thumb button release, hinge or back-tension release, and tension-activated release. Index finger releases are the most popular type and are attached to wrist straps, while thumb button releases are held in the hand and activated by your thumb. Hinge releases are activated by pushing your shoulder blades together, and tension-activated releases fire when the tension increases to a certain level.

Once you have your mechanical release, you can attach it to the bowstring where you would usually hook the bowstring with your finger joints or the "D-loop". Snap the jaws of the release around the D-loop, keeping your index finger behind the trigger for safety.

If you are using a wrist strap release, wrap the strap around your wrist according to the instructions. This type of release is great for relieving finger pain, as it allows you to pull the string back with your whole arm and back.

Now you're ready to draw the bow and shoot! Remember to keep your eyes on the target and your body still for the most accurate shot.

The benefits of using a mechanical release

Using a mechanical release aid when shooting a compound bow has several advantages over using your fingers.

Firstly, it increases accuracy and consistency. Using a mechanical release device allows for a much more consistent release of the arrow than a finger release. With a finger release, the archer's grip and finger placement on the bowstring can vary slightly from shot to shot, leading to inconsistencies in the arrow's trajectory. With a mechanical release, the bowstring is released the same way every time, resulting in more consistent accuracy.

Secondly, it relieves finger strain. Mechanical release aids reduce the amount of stress on the archer's fingers and hand, which is especially beneficial for archers who shoot frequently or for extended periods. By using a mechanical release, the archer can focus more on their aim and form, rather than worrying about fatigue or discomfort in their fingers. This is also true for beginners, who may struggle with the strength required to draw a bowstring with their fingers.

Thirdly, it prevents accidental release. Mechanical releases provide a more precise and predictable release, which can help archers improve their accuracy and consistency. The release of the bowstring is consistent from shot to shot, resulting in a more predictable release of the arrow. This allows the archer to focus more on their aim and form, rather than worrying about variations in their release.

Lastly, it is easier to learn for beginners. Mechanical release aids require less finger strength and provide a more consistent release, helping beginners build confidence and improve their accuracy more quickly than they would with a finger release method. They can also be beneficial for hunting, as they provide a smoother and quieter release of the arrow, helping hunters remain stealthy and avoid spooking their prey.

The history of the compound bow

The compound bow is a modern innovation in archery, with its roots lying in the ancient longbow. The longbow has been in use for several millennia, and while its construction has evolved over time, the basic design has remained largely unchanged.

The compound bow, on the other hand, is a relative newcomer, with its patent being granted in 1969 to Holless Wilbur Allen, a bowhunter from Missouri. Allen was dissatisfied with the limitations of the traditional bow, where the game could duck away from arrows due to their slower speed. Using physics, Allen developed a bow with cables and wheels (or cams) that acted as force-multipliers to boost arrow speeds. This new design was patented in 1969, with the patent being published on 30 December of that year. Allen's prototype, constructed in 1966, had a long pinewood riser and short limbs made from laminated oak and fibreglass.

Allen's compound bow was not an immediate commercial success, but it laid the foundation for future innovations. Tom Jennings, a renowned bowyer, recognised the potential of this new design and created the Jennings Compound Bow Corporation in 1972. Jennings' Model T, with its two cam wheels and cables, was lighter, easier to maintain, and more elegant than its competitors. It was an instant hit, selling 60,000 units per year by 1975. This success spurred other manufacturers to enter the market, and by 1977, roughly 100 different models of compound bows were available.

The compound bow's popularity grew rapidly, and by the late 1970s, it had become the dominant class of bow in the United States. Manufacturers experimented with new concepts and materials, particularly the shape and attachment of the cam wheels. The first single-cam compounds were introduced in 1975, offering a simpler design by eliminating the need to synchronise two cams. The development of mechanical release aids in the early 1970s also influenced bow design, leading to shorter bows that were favoured by bow hunters.

Today, compound bows continue to evolve, with advancements in materials, design, and technology. They are widely used in target practice, hunting, and international target archery, offering increased accuracy, speed, and customisability compared to traditional bows.

How to shoot a compound bow

Stance and Grip

Stand with your feet shoulder-width apart, at a right angle to your target. If you're right-handed, your left side should face the target, with your right foot slightly in front. If you're left-handed, your right foot should lead, and you should face the target with your right side.

Grip the bow so the weight is balanced between your thumb and fingers, in the centre of your palm. Keep your grip calm and loose.

Prepare the Arrow

Notch an arrow into the rest, then snap it into the notch. Pull the back of the arrow into the string until it clicks into place along the nocking point. Attach your mechanical release to the bowstring where the arrow attaches, snapping the jaws of the release around the D-loop.

Posture and Aim

Keep your eyes on the target and your chin parallel to the ground. Hold your bow at a right angle from the floor, keeping your grip loose and your elbow slightly bent.

Hold the bow still and even with the target throughout your draw. Use your extended arm as a guide to draw the bow straight back, pulling the bow back in a fluid motion, keeping your bow arm straight on target.

Find your personal anchor point—the place where you have the bow drawn fully back against your cheek. Play with your anchor point to find what is comfortable, but once you find one, pull back to this point every single time.

Form a second anchor point by trying to put your nose against the string.

Align the pin on your sight with the centre of your target, then make any final adjustments.

Release

Release the trigger by slowly laying your finger down, not pulling. Keep your body still and the bow aimed and even with the target for 1-2 seconds after firing.

Improving Your Archery Skills

Focus on calm, fluid motions. Keep your shoulders relaxed, chin up, and knees slightly bent.

Safety

Never dry fire a bow (release without an arrow knocked). This can cause severe damage to the bow and injury to the user and bystanders.
