FX D1 Airguns Pocket Chronograph

FX Air Rifle / Air Pistol Chrono

The FX Pocket Chronograph D1 (often referred to as the FX Pocket Chrono D1) is a newly released, upgraded compact radar based chronograph from FX Airguns, the Swedish manufacturer known for high-end PCP air rifles and accessories. It was officially the successor to the popular Pocket Chronograph V2.

Your provided description matches the official product details almost exactly, highlighting its key advancements for airgun shooters (and potentially subsonic firearm use) who need portable, reliable velocity measurement.

Main Upgrades Over Previous Models

• Built-in digital display: No longer requires a smartphone or external device/app for basic use. It shows real-time velocity (up to 1250 FPS), plus shot string stats like min/max/average velocity and shot count directly on the unit for faster checks and tuning.
• ¼-turn Quick Release mounting system: Enables tool-free, rapid attachment/removal in seconds, ideal for switching between rifles or setups.
• Included mounting options: Traditional barrel mount, Picatinny rail mount, 90° angled adapter, and the quick-release interface for broad compatibility.
• Radar technology: Works in any lighting (even dark) and weather conditions, measuring velocities reliably from around 400-1250 FPS (optimized for air rifle/sub-firearm ranges).
• Compact and portable: Palm-sized, lightweight, and easy to toss in a range bag without adding bulk.

It can still pair with the FX Radar App (via Bluetooth, presumably) for advanced features like detailed shot analysis, rifle/bullet libraries, and drop charts if desired but the standalone display makes it far more convenient for quick field or bench work.
