Stark SPORT 3 radar speedometer from the United States
The STALKER SP0RT3 radar is capable of emitting ultra-high frequency radio waves and measuring the frequency changes of the reflected echoes from moving objects. This is commonly known as Doppler radar, which consumes very low energy (about 0.005 watts) from invisible radio waves and is also very safe for close range and continuous use.
The STALKER SP0RT3 K-band sports speed radar is designed to measure the speed of various objects such as baseball, carnival balls, cars, tennis balls, and almost all other moving objects.
