MagnetoSpeed XFR Adapter

The MagnetoSpeed XFR Adapter bridges the gap between your MagnetoSpeed Sporter or V3 chronograph display and modern smartphones, enabling wireless data transfer and management of ballistic shot series. This dedicated adapter works in tandem with the free XFR smartphone application (available for both Android and iOS devices) to streamline the capture, storage, and analysis of velocity data directly on your mobile device.

Once paired with the XFR app, the adapter allows users to download current and archived shot series from their chronograph display, then organize and store multiple shot strings on their phone. Beyond simple data transfer, the application provides editing capability and email distribution of ballistic records—critical for shooters documenting load development, validation testing, or forensic documentation. The XFR adapter also enables remote reconfiguration of display settings, including unit selection (feet per second or meters per second) and sensitivity adjustment, without physical access to the chronograph display itself. Archived series management on V3 units provides long-term ballistic logging for handload development tracking and ammunition verification across multiple shooting sessions.

This adapter is essential for serious reloaders, precision shooters, and ballistics researchers who require detailed velocity documentation and historical shot-string analysis. Range officers conducting ammunition qualification testing, law enforcement ballistics specialists, and competitive shooters benefit from the ability to capture and archive chronograph data without manual transcription. Weighing just 0.05 pounds with compact dimensions (3.95 x 0.45 x 5.6 inches), the XFR adapter adds minimal weight or bulk to your chronograph setup while substantially expanding its analytical capability and data portability.

The XFR represents a modern solution for ballistic data management in an ecosystem where smartphones have become the primary platform for technical documentation and field note-taking. Compatibility is limited to MagnetoSpeed Sporter and V3 chronograph displays; it is not compatible with earlier MagnetoSpeed models. Note that ongoing feature additions and improvements continue to expand the XFR app's functionality beyond its current feature set.
