Description
Tighter groups in just minutes.
Did you know?
Squaring both ends of an arrow has been proven to produce tighter groups.
With the Mod Archery Arrow Spin Tester + Squaring Device, you can square each end of the shaft, then spin test for wobble at each stage of your build, from bare shaft to broadhead install.
In addition, check runout with the included runout indicator that stows away neatly on the squaring post.
