When selecting a compound bow, you must understand the several specific measurement for the compound bow. By understanding these specific measurements, you can ensure that the compound bow you select for purchase will be the best fit for your body and hunting environment. A compound bow size chart will show you the axle-to-axle length, draw length, and draw weight of the compound bows in the chart.
A compound bow size chart will help you to select the compound bow that best match your specifications. If you dont use a compound bow size chart, you may end up purchasing a compound bow that is either too long or too short for your body and hunting situation, and you may find yourself in discomfort or inaccurately with your compound bows. Axle to axle length is the distance between the cams of the compound bow.
Simple Guide to Compound Bow Measurements
Axle to axle length will determine how the hunter handles the compound bow in different environments. Shorter axles to axle length will allow the hunter to move quick with the compound bow, which is beneficial in tight environments. However, if the axle to axle length is shorter for the compound bow, the compound bow will have a steeper angle to the string.
This can result in mistakes when shooting the compound bow and will reduce the forgiveness of the compound bow. Axle to axle lengths that are longer will allow the compound bow to settle better onto the target. These is beneficial to use in open environments.
Draw length is the distance between the bowstring and compound bow when the hunter pulls the compound bow back. Draw length is important to your body. One way to determine draw length is by using the wingspan of your arms.
Measure from fingertip to fingertip and divide that by 2.5. However, a professional archer can provide the best draw length for you. If draw length is not correct, the compound bow will not allow the hunter to properly aim at a target.
If draw length is not correct, it is likely that the compound bow will result in poor accuracy. Draw weight is the strength of force that is needed to pull the compound bow back. The hunter and the size of the animal that is to be hunted determines draw weight.
If the compound bow is for young shooters, the draw weight should be low so that the compound bow is easy for the youth to pull. High draw weight may result in the development of bad habits with young hunters. Hunters of all ages can use draw weights between 45 and 60 pound for deer.
However, draw weights may be higher for larger animals. The hunter may adjust draw weight by turning the bolts on the bow limbs. As compound bows are used more, the strength of the bowhunter will increase the draw weight of the compound bow.
Let-off percentage is the amount of weight that is released from the string when the hunter reaches the full draw position of the compound bow. Let-off percentage determines the amount of weight that a compound bow hunter will have to hold in their position when aiming at the target. High let-off percentages will significantly reduce the amount of weight that the compound bow hunter must hold.
This will allow compound bow hunters to hold the compound bow in a full draw for longer period of time without shaking the compound bow. Low let-off percentages will retain more tension in the compound bow. This will allow compound bow hunters to develop better back tension when shooting at targets.
A high let-off percentage or a low let-off percentage compound bow will be better suited for those who value comfort while shooting at compound bows or who want more feel of the compound bows when shooting. There are compound bows with different cam styles and brace height. Compound bows that have single cams will be quiet when shooting the compound bow, but bows with binary or dual cams will allow the arrow to travel at a higher rate.
The compound bows brace height is the distance between the grip of the compound bow and the string. Shorter compound bows will result in arrows traveling at a higher rate but provide less margin for error. Tall compound bows will provide more margins for error in the release of the compound bows arrow but require more effort to draw the arrow back.
Thus, beginners and indoor archers will use compound bows with a taller brace height. Finally, compound bows should of be “tuned” on paper to ensure that the arrow is traveling correctly in relation to the compound bow.
