As already said, you need to go to a bow shop, and they can help you. Once you find your correct draw length, reach out and see if anyone has a newer (5 years or less) bow they want to sell with the same draw length. I have been shooting a bow since 1978 and I always tell everyone to bargain hunt for their first bow because you never know if you will stick with it. If you like it and want to continue, then shop for better stuff. Bows depreciate faster than a new car, so it is possible to get fairly new equipment at a real bargain. Just like a new golfer, I would recommend paying for a couple private lessons too. This cuts the learning curve way down and prevents you from developing any bad habits. check out Bowsite.com classifieds. Good Luck and welcome to the brotherhood!
