I was on a camping trip when a buddy of mine gave me this 2004 martin prowler it has a bent riser, and well to say the least its in pretty rough shape. I just got back home with the bow and did a couple measurements and i have a 2012 saber takedown riser that im gonna try to fashion up with the prowlers limbs and cams, id have to get all new measurements for the strings since the sabers riser is shorter and the limbs come off at a slightly different angle but after doing a little research i found out the dyna cam on the prowler doesnt have a draw length for the f-3 module? which is where im confused cause this bow has an f-3 mod on it, so im stumped there any help would be appreciated and pics of the finished bow to come. OH! and i forgot the bow had an hha sight bracket on it so im pretty pumped for this treasure i picked up should be fun to mess with probably gonna be my bow fishing rig. Only thing funny about it is the limbs are a completely different camo then my saber riser. lol but as long as it shoots pretty it dont gotta bbe pretty lookin.
