That isn't a yardage scale. It is a sight in scale. All of the numbers are evenly spaced.

Sight the bow in at 20 yards and write down the number on the scale.

Sight the bow in at 60 yards and writedown thenumber on the scaleand lock down the wheel with out moving it.

Subtract the low number from the high number and choose the yardage tape that is printed with that number at the top.

Take that tape and tape it to the wheel making sure that the 60 yard mark on the tapeis exactly under the needle where you locked it down when you sightedd in at 60 yards.

Sounds confusing but it is a simple as it gets and HHA has got this tape down to an exact science. They are dead on if you sight it in properly. In order to be as accurate as possible you must make sure your bow is tuned and that you, yourself,shoot as accurately as possible.
