What this chronograph does

Measures velocity using radar, so you don’t have to align optical screens or worry about lighting conditions. The built‑in sensors record atmospheric data, and the app lets you store shot strings, analyse spreads, and even read velocities aloud (so you keep your eyes downrange).

BC calculation helps you understand bullet performance. PRS mode gives you a shot timer and a digital level for side‑to‑side cant – useful for precision rifle matches.

Who uses it

• Target shooters who want velocity data without setup hassles

• Reloaders checking load consistency

• Airgun owners tuning their guns

• PRS competitors needing a timer and level

• Hunters verifying ammunition performance

What’s included

• FX Pocket Chrono Pro unit

• Rifle mount (fits Weaver/Picatinny and Arca‑Swiss rails)

• Tripod

• USB‑C charging cable

• Quick‑start guide
