I am tryn to set my old PSE up for my wife. How do you chnge the draw length with out going to bow shop??
That depends on how the cam is designed so we'll either need to know the year, model and cam option or see a photo. You'll likely have to press the bow which requires special tools. The best bet is to go to a proshop and have it done correctly. You may want to replace the string and cables while you're at it, depending on how old we're talking here.
x2 You will most likely need to take it to a shop to have put in a bow press. You could be a nice guy and buy her a martin. LOL no bow press needed. How old is your bow? You may be able to google some info on line.
