This amazing device is a spine tester, grain scale, and straightness checker all in one.

The Arrow Analyzer gives you a detailed readout of the static spine, gram & grain weight, and straightness tolerance of parallel arrows.
The BearPaw Arrow Analyzer works with all arrow materials of carbon, wood, and aluminum up to 23/64" diameter and at least 26" in length. Measures in 1 grain increments from approx. 16 grains up to 1,541 grains.
For measuring static spine, the Arrow Analyzer displays both industry standards. AMO spine, common for wood arrows, that is displayed in pounds (approx. measures in a range of 11-125#). ASTM spine (American Society for Testing and Materials), common for carbon and aluminum arrows, that shows deflection in a decimal (approx. measures from 2500 to 250 deflection).
Please note, you can view your readout on the Arrow Analyzer display, or you can view it on your PC or laptop. Viewing the readout on your PC or laptop requires a software download from the Arrow Analyzer web site.
