Go to the bowtec website and download the 2003 owners manual off of the main page, this will explain the draw stop feature.
The "s" is shorter, the "L" is for longer. This is a means of tweaking your draw length and letoff.
I went to the bowtech website and the infinity cams had a number that went 1 for where the L is, and a 10 where the S is. The new freedom Cam has a lot more adjustment notches then last years infinity cam and they did away with the 1 thru 10 markings. So I'm still a little confused. I'll try moving it a little at a time tommorow and see what effect it has.
It seems like the more towards the S I go the less letoff I should have and the more towards the L the more letoff I should get. I'm just guessing according to last years infinity cam specs. Is that correct?
