View Full Version : Cam Let Off Question

07-14-2007, 07:52 PM
I have a Martin Razor X with SE limbs. It is outfitted with nitrous cams. I have a 32-33 inch draw. My question is can I have these cams modified to allow 80% let off? (current set up is 65%) Or can I put on other cams to allow 80% and still get my draw length? If so is this something a sports shop can do or should it go back to Martin? My sons have the new Bengal with 80% M-Pro and I love that 80%!! Thanks for the help.

The draw modules on the cams determine the let off. If your shop doesn't have them you can order them from martin.

The Nitrous cams only can be had with two module configurations. Standard is 75% and optional is 65%. Letoff can vary some with draw length changes. I usually get about 71% letoff at 27" draw. You'll probably get a little more, closer to 75%. 80% was never an option with Nitrous cams.
