NateChrony v2.5 Chronograph

NateChrony v2.5 – The Ultimate Barrel-Mounted Chronograph for Airgun Precision

Meet the NateChrony v2.5, the newest evolution of our most trusted chronograph—now redesigned and more powerful than ever for serious airgunners. Replacing the v2 as our standard chronograph, the v2.5 uses the same hardware as our advanced SteadyShot model, which means you can upgrade to full motion-analysis capabilities via a simple software update whenever you're ready.

Designed specifically for air rifles, the NateChrony v2.5 is a barrel-mounted ballistic chronograph that delivers unmatched accuracy, ease of use, and reliability. Calibrated from certified master chronographs, it reads within 1fps of true velocity at 1,000fps—making it the most accurate device of its kind on the market. Whether you're tuning a PCP, testing pellet consistency, or just confirming power levels, you can count on the NateChrony to deliver precise results every time.

Barrel-Mounted for Accuracy – No More Missed Shots Unlike traditional optical chronographs that rely on external lighting and complex setup, the NateChrony mounts directly to your barrel using included adapters. This guarantees consistent alignment with every use and eliminates missed or inconsistent readings. It’s light, compact, and designed to travel with you—perfect for backyard testing or range days.

Use Your Mobile Phone as the Display

Forget tiny, hard-to-read screens and dead batteries. The NateChrony uses your phone or tablet as both display and power source. Simply connect to the NateChrony’s built-in Wi-Fi hotspot and load the interface in any web browser—no internet, apps, accounts, or permissions required. Any modern device with Wi-Fi and a browser will work, whether it's Android, iOS, Windows, or Mac.

Feature-Rich and Built for Tuners

The NateChrony v2.5 isn’t just accurate—it’s fully featured for those who want deep data: - Real-time velocity readouts - Current shot string display - Statistics: min, max, average, spread, and standard deviation - Voice readout for hands-free feedback - Live graphing for visual analysis - Four additional save slots, retaining data even when power is lost

All features are easily configurable via a clean, intuitive web interface—no tech wizardry required.

Software Upgrade Path to SteadyShot

Thanks to its shared hardware with our SteadyShot model, the v2.5 is future-proof. When you're ready to start analyzing your muzzle movement in 3D or tracking shot stability, simply upgrade via software and unlock a whole new level of performance data.

System Requirements (Simple & Flexible)

To use the NateChrony v2.5, you’ll need: - A mobile phone or tablet less than 5 years old with up-to-date software - A 5V standard USB power source - A browser that supports HTTP and JavaScript - A device capable of connecting to Wi-Fi without requiring internet access - Basic familiarity with your device’s browser and security settings

We even offer a built-in test page to verify compatibility before you begin.

Whether you’re shooting sub-12 ft/lb springers, 100 ft/lb PCPs, or testing different pellet weights, the NateChrony v2.5 gives you the clarity and confidence you need to push your airgun performance to the next level—no guesswork, no missed data, just precision.
