Stabili-Track
The tip records the hold. TargetOS turns it into a readout — peak draw, settle, aim time, hold — on every arrow, filed on the same card as the score.
Requires the separate Stabili-Track motion sensor. Feeds the same Metrics dashboard as everything else — one filterable history.
This is a real, unedited photo of a physical Stabili-Track tip — not a mockup or a 3D render. Engraved lid, green power LED, and the RJ11-style connector cable, shown next to a matching connector for scale.
Order a KitEight signals, tracked on every arrow, not just described in a feel — grouped in the app under six toggleable factor categories: Hold Time, Hold Steady, Peak Draw, Settle, Cant, and Advanced Heat Maps.
Does my 27in bar with 10oz hold better than my 30in bar with 8oz on it? Well now you can ACTUALLY see it on your target face.
Where the draw actually peaks, shot to shot.
How long it takes to settle into the shot.
Time actually spent aiming before release.
Steadiness through the hold, not a guess.
Self-referenced to your own hold, not an external zero.
Lateral steadiness during hold.
Vertical steadiness during hold.
Time spent in-ring through the last 500 ms.
Not a mockup — this is what the actual correlation screen shows, cross-referencing hold time, hold steadiness, peak draw, settle, and cant against the points each shot actually scored.
Two real methodology choices sit behind every correlation table above — not hidden, not hand-waved.
Every correlation table lets you switch what “reference” means. Draw Lab measures you against the personal baseline built from your own best takes — the law you're trying to reproduce. Rolling measures you against whatever's currently sitting in your filter — your own recent normal, not your best case. Same shots, two different questions.
Shots aren't forced into “better” or “worse.” Each measurement carries a real tolerance band around the reference — Hold Time ±0.50s, Peak Draw ±1.0°, Cant ±0.5°, Settle ±0.25s — and anything inside that band counts as At Baseline. Only what's genuinely outside the tolerance gets bucketed Low or High.
That's also what a line like “in-view average as % of Draw Lab: L/R 70% · U/D 129%” means — it's the current filtered view's average wobble, expressed as a percentage of your own reference. 129% means averaging 29% more wobble than your own established baseline, not an abstract number pulled from nowhere.
Stabili-Track doesn't grade you against an abstract ideal. It grades you against your own best draws.
Four things that don't show up on a chart but decide whether the chart can be trusted.
Orients the tip to how the bow is actually held, before anything else is measured. Skip it, and cant is graded against an arbitrary zero instead of your real geometry — every cant and hold-path number downstream depends on this being right first.
Once locked to the tip, the scorecard shows a real-time readout during the shot itself — acceleration (g), sampling rate (Hz), sample count, tip battery — visible the whole time you're at full draw, not just after.
Reverse-anchoring the hold path onto the hole only works if arrows are plotted in the order they were actually shot. Score with a plain number pad, out of order, and there's no honest way to connect that hold-path data to a specific arrow on the face.
A lighter mode for shooting without a full scorecard. Once a Draw Lab profile is saved and locked to the tip: Start/Stop Recording, plot on a simple canvas, a follow-through overlay, a buffer list of recent shots. Same lock-gating as the scorecard — no profile, no recording.
Not just how long you took to settle into the shot — what that settle time actually cost or earned you on the card.
This is the same settle timing from the tile grid above, but run against your own results instead of sitting on its own. Rushing into a shot and over-holding both show up here as the same thing: a settle-time band that quietly costs points.
Filter it against a single bow, a single distance, or a full season — the correlation is rebuilt from your own data every time, never a generic curve.
The kind of question this exists to answer: when I added 4oz to my front bar, did my hold times drop? If so, by how much?
The tip records motion at 100Hz — so the amount of data collected per shot is enormous compared to other motion tracking devices. If that data were transferred over Bluetooth (BLE), each shot would take anywhere from 1½–5 minutes to transfer, and would still need to be rebuilt in the app afterward — consuming significant power and memory on both devices. This is why the athlete instead chooses 1 of 3 different WiFi configurations for transfer.
147,526 B
~144 KB per shot at 100Hz. Over BLE (20-byte packets, ~15ms per write): 7,377 packets → ≈110.7 sec — about 1 minute 51 seconds, for one shot.
71 KB
≈3,634 packets over BLE → ≈54.5 sec to transfer a single shot.
275 KB
≈14,079 packets over BLE → ≈3 min 31 sec to transfer a single shot.
A full 30-shot session at the same average shot size: ≈4.43 MB total → ≈221,289 packets over BLE → ≈55.3 minutes if sent back-to-back. WiFi is not an aesthetic choice — it is the only transport that gets this much real motion data off the tip and onto the scorecard in a session that still fits inside a practice.
No staged data, no simulation — four shots pulled directly from a Stabili-Track session. Each card is the tip's actual on-device readout: the plotted post-settle aim path into the target face, next to the real Hold Time, Peak Draw, and Settle numbers the tip recorded for that arrow.

Your tip locks to the first phone it bonds with, on purpose — only a direct USB connection can reset that lock. Full explanation and the reset tool live on the Support page.
Setups, scores, the day, the story — it all lives together.
