New Hot Lap™ Lti™ System Works By Sending An Invisible IR Signal From the transmitter across the track. When your car passes through the beam, it is picked up by the receiver that is connected to the display, triggering the timing. The display shows your lap times as you race much more accurately than hand held stopwatches.
