Replace a damaged or missing Optic Lap Receiver and get your lap times back. This unit is the same receiver included with the MXL Strada, MXL Pista, and MyChron3 XG-Log auto dashes. It will also work with the EVO4 data logger if GPS lap timing is not used. The 2.8 meter (9.2 foot) cord with a male 4-pin 712 (screw-in) connector allows easy positioning anywhere on the vehicle. MyChron3 series Auto dashes (except the XG-Log), MXL Pro, MXL2/MXS/MXG, and EVO3 series data loggers use the MyChron Optic Lap Receiver with 719 Connector , which is the same unit but with a male 4-pin 719 (snap-together) connector.
