Coop's Bowsmith spine tester with arrow on the rail

Index your arrows so the spine is on the top of the shaft for a much improved flight

We are continually upgrading and improving our archery equipment to match the ever-growing demands of our shooters. Our Arrow Spine Tester Pro is more cost-effective and more versatile than any other machine on the market, including the ram spine tester for arrow tuning and broad-head tuning 

  

SUPER TUNING ARROWS

Our spine tester design uses spring pressure instead of dead weight. 

We have found it makes locating and measuring the spine much easier if you can adjust the pressure exerted on the shaft from one to four pounds and greater yet for crossbow bolts.

Consistency is what we are looking for!

Stand up the towers, attach the dial gauge, and you're ready.
We strongly recommend adding our high-quality screwdriver-type L wrench when you place your order.

Make sure you're getting what you paid for. Not all shafts are the same.

Note: this is our original design. Slight modifications have been made since, but it works exactly the same.
