FX Pocket Chronograph D1 Chrono
The FX Pocket Chronograph D1 is the next evolution of FX’s widely trusted pocket chronograph system. Designed for shooters who demand fast, reliable velocity data wherever they shoot, the D1 introduces major upgrades that make chronographing quicker, cleaner, and more intuitive than ever before.
Compact, lightweight and built for real-world use, the D1 delivers precise velocity readings directly from the unit — no phone required.
