Follow the link below to Diamond Archery' s online catalog, go to page 2, and tell me what it says in the lower right corner of that page:

Here' s a hint: " Cam Technology Licensed by Bowtech"
So basically, if Diamond is indeed manufacturing their own cams, it' s simply because they bought and copied Bowtech' s cam design. I think I might have seen where up until now Bowtech has outsourced their machining (which will no longer be the case soon), and it might be the case that the folks at Diamond do the machining work for them...especially given that Diamond is in Shreveport, very close to where Bowtech used to be in Bossier City. Regardless, the fact remains that Diamond bows use Bowtech cams...even if they do make them for themselves. So, I guess " technically" Diamond may " make" (manufacture) cams for Bowtech, but make no mistake about it...Bowtech, Diamond, and Parker all use BOWTECH cams.
Diamond may make Bowtech' s cams, but they still buy the rights to use their cams from Bowtech.
