Coop's Bowsmith Spine Alignment Tester ProItem Number: 5896
This is not your typical spine tester! Coop's Bowsmith Spine Alignment Tester Pro helps you find the stiffest spine on your arrow shaft so you can perfectly tune your arrows.
This equipment helps you locate the stiff spine of the shaft allowing you to align the spine in any preference you want. This gives you more shot-to-shot consistency between arrows. For traditional archers, it is typically aligned with the cock feather and/or broadheads.
The roller bearings also allow you to check arrow squareness, broadhead spin, and runout. This is mainly for carbon arrows.
Coop's Bowsmith Spine Alignment Tester Pro is completely adjustable for any size arrow. It operates using spring tension over a dead weight.
This is a great tool for your workshop or garage. Measures approximately 24-1/4" long x 2-1/4" wide. Solid metal construction and easy to assemble and use.
