Athlon · Doppler Radar Chronograph
The Athlon Rangecraft Velocity Pro — the smart-money Doppler chronograph
A few years ago, putting real Doppler radar on your shooting bench meant spending the price of a decent rifle. Then Garmin’s Xero shrank the technology into a box the size of a paperback and the personal chronograph grew up overnight. The Athlon Rangecraft Velocity Pro is the next move in that story — a personal Doppler radar chronograph that does the same fundamental job as the Garmin Xero for materially less money.
±0.1% velocity accuracy, no mounting, suppressors and muzzle brakes no problem, USB-C charging, a free app with no subscription — at $799, several hundred dollars under the Garmin’s Australian retail. Below we’ve done the head-to-head properly, against both the Xero C1 Pro that existed when the Athlon launched and the newer Xero C2 that Garmin released after it — specs side by side, including where each Garmin still wins.
What It Actually Does
Doppler radar at the bench — no skyscreens, no mounting
If your last chronograph involved poles, diffusers and a wild swing on cloudy days, this is the upgrade.
Every meaningful ballistic number — drop, drift, energy, retained velocity at the target — starts with one figure: how fast the projectile is actually going. For thirty years that came from optical skyscreens on poles: fussy in bright sun, fussy in flat overcast, easy to shoot if you misjudged the height. The Velocity Pro is a Doppler radar chronograph. You sit it on the bench beside the firing line, point it downrange and pull the trigger. Nothing touches the barrel, nothing sits in front of the muzzle, and because the radar tracks the projectile rather than the muzzle blast, suppressors, brakes and compensators make no difference. It reads velocity, standard deviation, extreme spread, kinetic energy and power factor live on a 2.4″ transreflective (sunlight-readable) screen, stores the session on-device, and syncs to a free phone app.
Athlon vs Garmin Xero — The Honest Head-to-Head
Specs, not spin — against both the C1 Pro and the C2
The Garmin Xero is an excellent chronograph — Garmin has built reliable electronics for decades and it shows. We’re not going to pretend otherwise. What we will do is lay all three units on the spec sheet so you can decide. The Xero C1 Pro is the unit the Athlon originally squared up against. In January 2026 Garmin released the Xero C2 — a genuine step up in features, at a genuine step up in price. Here’s where each one lands.

Where the Athlon wins
Price, and not by a little — at $799 it undercuts the C1 Pro by roughly $300 and the C2 by around $450. Velocity floor — it reads down to 65 FPS where both Garmins start at 100, which is the difference between capturing a traditional recurve arrow or a tuned-down PCP airgun and not seeing the shot at all. A dedicated airgun mode. And water rating — Athlon’s published IP67 is dust-tight and rated for 1m immersion, one step beyond the Garmins’ IPX7 (which carries no dust rating). Plus a local retailer who answers the phone in Queensland.
Where the Garmins win
The C1 Pro is about 28g lighter — the mass of a single 9mm cartridge — which matters only if you pocket a chrono on a walk-up day, and it has the longer track record in shooters’ hands. The C2 is the genuine premium unit: a 10× faster processor that tracks up to 10 shots per second for rapid strings, Garmin smartwatch control, a direct Applied Ballistics AB Comms link that pushes muzzle velocity straight into the AB solver, a resume-session feature, and reinforced housing rated for direct rifle mounting. If you shoot fast strings or live inside the Garmin/Applied Ballistics ecosystem, those are real, worth-paying-for features.
Where they’re honestly tied
Accuracy on rifles and pistols. The Doppler radar approach itself. Suppressor and brake compatibility. USB-C charging. Physical-button interface. A free, no-subscription app. All three read velocity, SD, ES, KE and PF live on the device.
What You Get For $799
Six reasons it lives on our shelf
The same headline accuracy figure the Garmin publishes, at materially less money.
Sits on the bench beside the firing line — nothing touches the rifle, nothing to shoot through.
From a slow recurve arrow to varmint-magnum velocity — a wider floor than either Garmin.
Dust-tight, 1m-waterproof housing and a sunlight-readable 2.4″ LCD showing velocity, SD, ES, KE and PF live.
A full range day from one charge, on the same USB-C cable as your phone — no proprietary charger.
The Athlon Ballistics app syncs your sessions, tags loads and stores 50 sessions on-device — free, forever.
Who Buys One
Five shooters it pays for fast
Real velocity, SD and ES from every powder charge — your data, from your rifle, not someone else’s manual.
Confirm your load’s real muzzle velocity from this barrel, on the day — the number your solver actually needs.
Power factor, ES and SD live on the screen — build the load with data, not hope.
A dedicated airgun mode and a 65 FPS floor make regulator setup and slug tuning data-driven, not a guess.
Confirm real arrow speed with your arrow weight — sight tapes get easy when the input is measured, not estimated.

Common Questions
Athlon Rangecraft Velocity Pro FAQ
Is the Athlon actually as accurate as the Garmin Xero?
On the published spec, yes — the Athlon and both Garmin Xero units publish ±0.1% velocity accuracy on rifle and pistol projectiles, the figure that matters for almost every shooter. Independent testers have reported the Velocity Pro matching reference chronographs shot-for-shot. There is no meaningful accuracy gap between them.
Should I buy the Athlon, the Xero C1 Pro, or the newer Xero C2?
If your job is load development, confirming a hunting load, or tuning an airgun or bow, the Athlon does that at ±0.1% for around $799 — roughly $300 under the C1 Pro and $450 under the C2. If you need to capture rapid-fire strings (up to 10 shots per second), control the unit from a Garmin watch, or push muzzle velocity straight into the Applied Ballistics solver, the C2 is built for that and earns its ~$1,249. The C1 Pro sits in between — dearer than the Athlon, without the C2’s new features. For most Australian shooters, the Athlon is the smart-money pick.
What’s the difference between the Xero C1 Pro and the C2?
The C2 arrived in January 2026 with a 10× faster processor that tracks up to 10 shots per second, Garmin smartwatch integration, Applied Ballistics AB Comms for direct muzzle-velocity transfer, a resume-session feature, and reinforced housing rated for direct rifle mounting. The core radar and ±0.1% accuracy are the same as the C1 Pro; the C2 adds speed and ecosystem features at a higher price.
Will it read through a suppressor or muzzle brake?
Yes. Because it is a Doppler radar unit that tracks the projectile in flight rather than triggering off muzzle blast or a light interruption, suppressors, brakes and compensators do not affect the reading — the same advantage the Garmin units share over older optical chronographs.
How do I set it up? Does it need aiming?
Place it on the bench beside your firing position, roughly parallel to the line of fire and pointing downrange. No skyscreens to align, no tripod required for normal bench use (there is a ¼-20 thread if you want one). Power on, pick the mode, and fire — velocity shows live, shot to shot. Setup takes under ten seconds.
Will it read airguns and arrows?
Yes — this is one of its real strengths. It has dedicated airgun and archery modes, and its 65 FPS velocity floor is low enough to read slow traditional bows and tuned-down airguns that both Garmin Xero units (100 FPS floor) will not see. For PCP tuners and traditional archers, that’s a meaningful edge.
Is the app free? Any subscriptions?
Free, no subscription. The Athlon Ballistics app is a free download on iOS and Android, syncs your sessions over Bluetooth and lets you tag and review your data. For the record, Garmin’s ShotView app is also free — neither maker runs a subscription on these chronographs.
Do I need a firearms licence to buy a chronograph?
No. A chronograph is a measurement instrument, not a firearm or firearm part — no licence and no genuine reason required. It ships as a consumer electronic, Australia-wide, with no dealer-to-dealer transfer. Most owners will of course use it alongside licensed firearms or equipment.
