On my bows, if I lay the arrow across the top cam it will run parallel to the riser and would point directly at the same edge of the bottom cam.
If you find that when held flat on the cam, that the arrow angles down across the riser or outward then your cams are leaning.
While this procedure works correctly for two cam bows and hybrids, I am not sure that it works correctly for the binary cammed bows like the Bowtechs. I thought I heard that there was a certain amount of cam lean that was built into them.
