When you see the AMO 60 ″ (this is the AMO size) you want to subtract 3.

60– 3 = 57 (You subtract 3 for recurve bows … compound bows are a little more complex).

69 ″ is mosting likely to be the bow size nock-to-nock when the bow is strung.

But listen. I hear regularly individuals say they can do this easy math as well as recognize what their bow size is.

This is the string size.

Why do they call it bow size … I have no hint. But I want to make this very clear.

Place it on the secure located on the camera and then wrap it around the cameras. After that bring the string to the other secure on the other side of the bow.
