i saw a hand tool that measures draw weights up to 100 lbs at the local hardware store. Don't have a picture now, but that tool is battery operated with a hook at its base. When pulled on it, it gives a read of what the draw weight is in lbs. I wonder if this can be use to test bow draw weight and assuming you turned both limb bolts equally... i wanna set my parker spitfire bow to 60lbs from 55.

Sounds like it would work if you have the ability to read the scale while drawing. You should only need 1-2 turns to increase the weight 5 lbs.

Caution: Make sure you draw the bow with an arrow nocked to avoid a potential dry fire. Make sure you draw the bow pointed in a safe direction.

Cabella's sell one that is quite accurate although only a spring. only 28 bucks.

so 1 full turn on each limb = 2-3lbs or 1 full turn on both limbs = 2-3lbs? my manual says, a full turn = 2-3lbs but didn't specify whether it's per limb or both limbs

Both limbs. One full turn on each limb will give the 2-3 lb increase mentioned in your manual.

Arriving at the exact weight is unnecessary. If you are at 60, then take a 1.5-2.0 turns off to arrive around 55. If the bow feels good and you do not have spine issues, then the exact numerical weight is not important.

what exactly is spine issue? keep seeing it.. might have to google later if no one respond

I have that one. It works just fine!

Differing draw weights require different spine (stiffness) arrows. When you change the draw weight of the bow, you need to be aware that the spineof the arrows may no longer be appropriate. However, arrows are spined for a range of draw weights which comes from the manufacturers charts or even software like Archers Advantage. Most folks rely on the charts.

BE CAREFULL not to back it out to far...
