tested and measured to ensure compliance with our strict performance standards.

Performance testing is completed using a Custom Chronograph, Heavy Duty ProShop Meter and

digital scales*. Speed ratings have been obtained with factory installed brass nock and string

silencers. The use of these accessories decreases velocity by 5-8 fps. Final factory test results are

documented in writing and attached as a “Birth Certificate” to every bow shipped.

IBO speed ratings are the industry standard and are calculated by shooting a 350-grain arrow

using a 70# bow with a 30” draw. Speeds for the Razor Edge are achieved using a 300-grain arrow

shot at 60# with a 29” draw.
