I am getting ready to purchase a used bow for my wife, she has expressed some interested in archery and I want to get her a used starter bow. I found a PSE Spyder for a good price but have a question about the adjustability. It is currently set at a draw length of 23" I need to know if it can be adjusted to 25". Here is a pic of the cam, I'm not real educated on all the cam settings and how it works. I think this is set on the shortest draw length and I should be able to adjust it longer but I wanted to get some expert opinions before I purchase the bow.
