Ram Spine Tester

The Ram arrow spine tester allows you to sort your arrows for perfect consistency of spine (dynamic stiffness). 

Precisely index arrow nocks to the stiffest portion of the arrow shaft for the tightest groups. Check the concentricity of your broadheads to an amazing +/-.0005" for an awesome hunting accuracy. 

Measure the straightness of arrows from the tip to tip. Monitor the degradation of arrow spine over the course of the season to catch problems before they show up on your score card.
