Alfano IR Receiver
The Infrared Receiver typically gets mounted on the fairing of your kart and receives an infrared beam from a beacon set on the track to record your lap times. All of the alfano gauges come standard with a magnetic pick up but if your track does not have magnetic strips under it than you would need to use this IR Receiver to get your lap times.
This receiver is compatible with the Alfano Astro, Alfano Pro Plus, and the Alfano Pro V2. (this will not work with the old standard Alfano Pro)
The IR receiver does require a Transmitter that is placed on the track for pick up.
