It's one, or both, of the cables where they hook to the cam axlels. Bowtech OD binary has dual yokes. Very tunable.
Most others just has one, like on most single cam bows. But Hoyts and some other two cam bows use them too.
It just makes tuning easier and you can work with cam lean better.
On Binarys bows, such as Elite, about the only thing you can do is shim or swap places with the limbs. If that doesn't work, then you need new limbs.
