bones, Core Archery by Larry Wise is a good book for teaching form, albeit a bit technical, which you might not be ready for yet. However, learning to shoot properly from the git-go is better than trying to correct bad form.

One of the better sources for care and tuning is Easton's Maintenance and Tuning Guide. You can download this from www.eastonarchery.com. And the answer is yes. Every bowhunter that cares enough to spend the money and attempt to kill an animal owes it to that animal and themselves to be able to tune their own equipment. Knowing what you equipment is doing, knowing how to tune it, and shooting it properly ius a big confidence builder for when you go hunting. Just knowing where that arrow is going without having to see it is great.

I'll try to explain something. Many people go to a pro-shop to get their bow tuned. A pro-shop cannot tune your bow correctly unless you are the shooter. No two people will shoot your bow the way you do. Slight differences in hand pressure, etc, can make a huge difference in how your equipment performs.. They can maybe help you make adjustments, but you have to shoot the bow. So why not just learn how to do it yourself? Then you'll have an added benefit of confidence, pride and keeping your money in your pocket.
