Sports Radar 65 MPH Tuning Fork
A 65 MPH X band tuning fork for spot checking that a Sports Radar baseball speed gun is reading correctly before a bullpen or a game. Strike a tine on a hard surface, hold the ringing fork 4 to 6 inches in front of the unit and read the display, where the expected window is 64 to 66 MPH. It works with the SR3600, SR3800, SRA3000 and the DT series detectors. This is a verification check and not a calibration tool, because these guns have no user calibration and a unit that reads outside the window goes back to the factory.
