I came across this unique gadget while talking to a friend who uses this company's baseball glove radar unit that goes on the back of a catcher's mit to clock the incoming pitch.

This is a bow-mounted chronograph using doppler physics to measure speed. Says it's accurate to within +/- 2% through a range of 150-450fps.

Just wondering if anyone has used this device before? It would be nice not to have to lug along my chrono, stand, lighting kit, etc.....
