It is really neat that You got your girlfriend to learn about shooting a bow Buckmaster 101.....I would get her an arm guard so she's not worried about hitting her arm or evena good thick long-sleeved sweater or shirt is better than nothing.If she's pulling 45 lb pull already that pretty darn good and it is enough to kill a deer with!Tell her we're all thrilled to death she's learning to shoot and keep us up-dated on how well she's coming along!
