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 / Valken / Umarex projectiles and Airsoft BBs often 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.
