XRadar Chronograph X-Radar: Byrna, Umarex, Airsoft, Paintball up to 698 fps

The Byrna factory owns 8 X-Radars for velocity testing their products. The Yellow Button version of the X-Radar handheld chronograph velocity tests Byrna / Umarex projectiles, Airsoft (0.2g and heavier), and Paintballs up to 698 fps. Works indoors and outdoors using advanced 24 GHz doppler radar technology. Measures both Velocity (150 – 698 fps) and Rate of Fire (4 – 30 bps). Accurate. Reliable. Easy to use (see photo #2). Standard 9 volt battery power (not included). MOST ASKED QUESTION: Red Button or Yellow Button X-Radar? ANSWER: for velocity testing Paintballs exclusively up to 399 fps, the Red Button X-Radar has been optimized for this purpose and is the best choice. Byrna / Umarex projectiles and Airsoft BBs can exceed 399 fps. So for velocity testing these various faster projectiles up to 698 fps, as well as Paintballs, the Yellow Button X-Radar is the best choice. Both are available on Ebay.
