Learning how to adjust draw weight on a compound bow is an absolutely necessary lesson that every bow hunter needs to know.
You dont want to be pulling a draw weight far to heavy for you and not have an understanding of how to adjust it, so that’s why we’ve put together this post.
Believe it or not the process is actually pretty simple and straight forward. We will say though that what we are about to teach you will work on 99% of most modern bows, however their will be some out there where the draw weight is not adjusted this exact way. If that’s the case consult your owner manual for the way they recommend to adjust your bow.
Adjusting draw weight on a compound bow
The reason why knowing how to adjust your draw weight is so important is because shooting your bow at the correct draw weight for you is critical. Not all Compound bows are able to even be adjusted, but most on the market these days are able to be adjusted.
When shopping for a bow you’ll notice that their is often a large choice of bows that have different adjustable draw weights. On the extreme you’ll have bows that adjust anywhere from 10lbs – 70 lbs. On the other end of the spectrum you’ll find ones that have less range such as 55lbs – 70lbs.
Either way you need to find the bow that suits you, and your needs. If the bow is for a youth then I suggest a large draw weight range so they have room to grow into larger draw weights. If the bow is for an adult then maybe the latter of the two might be a better option.
Locate the limb bolts on your bow. Most are located at the top and bottom of the top and bottom limbs. The will usually be a hex bolt that is easily adjustable.
When the hex bolt is tightened clockwise they put more stress on the limbs, resulting in a higher draw weight. When the bolt is loosened counter clockwise they take the pressure off, obviously resulting in less of a draw weight.
To reach the maximum draw weight the bow is intended for, tighten the hex bolt clockwise until they can not be tightened any further. Do not force the bolts as this will result in stripping, but make sure they are tight and snug. When the bolts reach that point, the bow is at it’s maximum draw weight range.
To reduce the draw weight, just do the reverse.
IMPORTANT SAFETY TIPS:- Be sure to tighten and loosen both sides of the limb bolts equally. If you dont this will create unequal strain on the limbs and when the bow is fired this can lead to catastrophic failure, or unwanted ware and tare.
Also be sure not loosen the bolts passed the point of lowest draw weight, as this can cause the limbs to comer off while under pressure and this can also lead to catastrophic failure.
Once you have adjust the limb bolts, measure the draw weight on a bow scale. Alternatively you can just use a normal set of fish scales but you will have to become creative if your doing this by yourself. If you have a second person their to read the scale while you pull down on the bow then normal scales are fine.
Bow scales are designed in a way that when you draw the bow, it will automatically record a lbs weight mark as you go through your draw cycle. Obviously recording the mark at the valley part of the draw cycle as this is when the draw weight is at it’s true weight.
If your using scales you can just hold your bow like normal, hook the bow scale on the d loop, and pull back as if you normally would. (nock an arrow in case of accidental fire, this way you wont dry fire your bow and shatter the limbs).
As stated, the bow scale will automatically record your draw weight.
If using fish scales, hang the scales from a wall or something stable.
Put the hook from the scale, through the D-loop.
Pull down on the bow until you reach what you think to be sitting at the valley, and be careful not to roll over and complete the cycle, as then it becomes a real pain in the ass.
As you hit the valley, have someone read out what the draw weight was. If you dont have a second person you can do it yourself, but it’s just a little harder.
Voila, there you have it, draw weight adjusted.
