But how do you do the alignment and the centering of the arrow? To answer this question, in this article we will give you our best tips.
The importance of the alignment and the centering of the arrow
The alignment and the centering of the arrow are an important step to transmit the thrust of the limbs to the arrow in the most straight way possible. To aim and hit the target, the arrow must be aligned with the string. It must be centered in relation to the Berger Button.
What are the functions of a Berger Button?
The Berger Button has two functions:
- Statistical: the Berger Button allows you to adjust the arrow's distance and therefore the correct positioning of the arrow in the plane of the bow.
- Dynamically: the Berger Button allows the arrow to compensate for its fishtailing during its trajectory.
For the alignment and the centering of the arrow, it is the static function of the Berger button that interests us as well as the positioning of the arrow in relation to the piston of the Berger button.
How to do the alignment of an arrow ?
The arrow must always be in the vertical plane materialized by the string which is itself located in the middle of the limbs. The alignment of the arrow on your bow ensures that the arrow will exit in a straight line to the target. This is one of the first adjustments to make on your bow.
The alignment of the arrow is done through the use of a Berger button. Here is a simple method to help you do it:
- Put a Beiter shim (limb alignment shim to help with bow alignment) on each of the two limbs a few inches from the grip.
- Visually place your string in the grooves of the two wedges.
- Check the position of your arrow point in relation to your bowstring.
If your arrow is too far to the outside, pull out the adjustment ring on your Berger button. If your arrow is too far inboard, pull in your Berger Button adjustment ring.
This alignment will help reduce horizontal wobbling or fishtailing of the arrow. It also limits any contact between the arrow or its tail and the bow or arrow rest.
Centering the arrow: how to do it?
The centering of the arrow is very important so that the arrow can leave the theoretical center and the center of balance of the bow.
To do the centering of the arrow, the middle of the shaft should be in the center of the piston of the Berger button. Now you should adjust the horizontal position of the Berger button or arrow rest so that the arrow point is aligned. Next, simply loosen the arrow rest clamping screw. Before you tighten the arrow rest, make sure that the pin is only one millimeter above the arrow.
If you want to mark the center of the bow, tape the limbs near the riser. Then mark the exact center of each limb with a vertical line. If you are using a compound bow, mark an additional line about 5 mm to the left of the center line: this is the center of balance of the bow. Now to center the arrow, line up the string and these marks on the limbs by eye.
Our tips to make right the alignment and centering of the arrow
Here are our top tips to make right the alignment and centering of the arrow:
- Generally, it is always advisable to align the arrow in line with the center stabilizer to promote the release of your bow in the vertical plane.
- As a first step, it is always recommended that you seek the assistance of your coach to find the right setting, regardless of the bow you are using.
Indeed, the coach will be able to guide you, help you and teach you how to do it, especially if you are a beginner.
