Whatdraw length module is on the bow?

I have a Code and the cam comes with a draw stop screw so you can fine tune your valley. This will also prevent the string from stopping on the buss cable post as you describe.

So either they didn't install it (the bow is shipped without the draw stop screw in place) or you have a #1 or #2 module on your bow in which case they do not accept the draw stop screw and the buss cable postIS the back wall. Mine stops on the post as well as I have a #1 module (31in draw for the code) but mine does not make the noise you describe. I can hear it hitting but it's very faint, not going to be an issue hunting.

For the code the #1 module equates to a 31in draw and the #2 is a 30in draw. If I'm not mistaken with the Truth the #1 will equal a 30in draw and the #2will give you a29in draw.

It's easy to tell, if your module is held in place with three allen head screws then you should be able to install the draw stop set screw. If it is attached with only two allen head screws then it's most likely a #1 or #2

The number will also be etched into the module itself, mine reads RSH1

Good luck and report back with what you find out.
