The tech: GPS nock design
Built where the signal gets out
How the Nockout GPS nock is laid out: the antenna in the nock head, the electronics sealed for the shot, and an honest note on fit and tuning.
Antenna
Why the nock?
Carbon shafts block GPS and radio signals. So the antenna and radio sit in the nock head, the part that stays behind the end of the shaft. The battery and board sit inside the shaft, where they’re protected.
LED
Lit from inside.
A green LED at the back of the electronics bay shines through the translucent nock head, so the whole nock glows, without weakening the string seat.
Electronics
Sealed for the shot.
The electronics are potted in epoxy so the shock of the shot can’t shake solder joints loose.
Fit
Fit.
We’re building two versions: a half-moon nock for crossbow bolts and a slotted nock for bow arrows. We’ll publish a tested compatibility list before the campaign.
Tuning note
Rear weight changes how an arrow flies.
Any tracker adds weight at the back of the arrow or bolt, which shifts its balance (front-of-center). We’re testing tip and insert combinations so you can keep your arrows and bolts flying true, and we’ll publish what we find.
Where it stands
From prototype to production.
Nockout started as 3D-printed prototypes sized to real bolts. Updates on every step are on the Updates page.
Before you hunt with it. Hunting regulations vary by state and province. Some places restrict electronic devices on arrows or bolts. Check your local regulations before using Nockout in the field.
Safety. Always inspect arrows, bolts and nocks before shooting. Use only nocks rated for your bow or crossbow. Never shoot a prototype or a 3D-printed nock.
Your next arrow shouldn’t be your last.
