FX Pocket Chrono D1

FX Pocket Chrono D1 is a compact radar chronograph that turns every shooting session into a precisely measurable discipline. Thanks to the integrated display, smart app, and radar technology, you get an instant overview of shot velocity and consistency without having to set up a large, fragile device in front of the muzzle. The small body fits in your pocket, yet its performance matches large bench chronographs – ideal for tuning air rifles, monitoring shots, and serious training.

Built-in display and complete shot statistics

FX Pocket Chrono D1 has a built-in clear display, so you see the basic data immediately right on the device – without needing to reach for your phone. The display shows the current shot velocity, and together with the app you also get complete series statistics. The chronograph works in the range of 400–1,250 fps (122–381 m/s), covering the typical velocities of airguns.

Operation is as simple as possible – with a few buttons you can quickly set the desired mode and values. Via Bluetooth you connect the chronograph to your phone, and in the official app you get clear graphs, statistics, measurement history, and the option to save and compare results. 

Radar technology – reliable operation in any weather

Unlike classic optical chronographs, FX Pocket Chrono D1 uses radar wave measurement. This means it is not dependent on optimal light conditions.

Radar technology also ensures reliable operation even in adverse weather conditions. Rain, changing light, or shade will no longer interfere with your measurements.

Two mounts – for barrel and Weaver/Picatinny rail

The package includes two practical mounts that significantly extend the range of use. The first mount is designed for barrel mounting – you attach the chronograph directly to the barrel and measure velocity as close to the muzzle as possible. The second mount is designed for installation on a Weaver/Picatinny rail, so you can easily attach it instead of or alongside accessories on your gun.

Charging and operation

Power is supplied by an integrated rechargeable battery, which you simply charge via a USB-C connector. This way you don’t have to deal with buying and replacing batteries – just connect a standard USB-C cable and after a short while the device is ready to use again.
