How to Spin-Test Your Arrows for a Perfect Flight Path
Oct 26, 2025
Why Arrow Flight Matters Most in Hunting Season
When that big whitetail finally steps into range, confidence is everything. Even a perfectly tuned bow won’t compensate for an arrow that’s not built correctly. Most alignment issues happen invisibly — and that’s where spin-testing comes in. Arrows take a beating from practice, travel, and field use. Taking five minutes now can make the difference between a clean pass-through and a missed opportunity.
Step 1: Checking Straightness Before the Hunt
A proper spin test checks your arrow’s true alignment — from insert to nock.
Center the arrow on your modsaw’s bearings. Gently spin it and watch the tip for wobble using the wobble indicator.
Any wobble = something is out of true: maybe the broadhead or field point, insert, or the shaft itself.
Step 2: Identify the Problem
If you notice wobble:
First, check that the broadhead is seated correctly — sometimes debris or gunk can prevent proper seating.
If wobble is still present and you hot-glued the insert in, heat and remove the insert. Clean the insert and arrow shaft with a Q-tip and some acetone. Before gluing in the insert and with a broadhead/field point mounted, seat the insert into the shaft and begin quarter-turning until wobble lessens.
Still wobbling? Use the squaring post on your modsaw to resquare the end. Then, once again, check every quarter turn for optimal positioning.
Pro Tip: Follow these same steps for the nock-end of your arrow!
Step 3: Re-Test Until It’s Perfect
Spin-test every arrow after:
- A missed shot
- Heavy target sessions
- Broadhead changes
- Travel to/from camp
Premium shafts and broadheads also take wear. Catching minor errors early prevents inconsistent grouping or broadhead flight issues.
Step 4: Check Straightness On the Go
Before you head out on your hunt, check your arrows with the broadheads that you’ll be using to ensure they still spin true. Using your modsaw or SpinEX, spin the arrow. Is it still tuned? You’re ready to put it in your quiver and head out. If not, work your way back through step 2 until the arrow spins perfectly.
Pro Tip: For tuning on the go, use the SpinEX Precision Arrow Spinner — engineered for micro-level accuracy and compact enough for gear bags and truck beds.
