Our race communications systems are extremely easy to use. There are two types of system available:
2-way radio or Bluetooth.
The kart to pit communication systems work like this:
The driver is equipped with a microphone and in-ear speakers within their helmet. This then connects to a radio transmitter/receiver that goes inside the kart, or a Bluetooth unit attached to the helmet, allowing the driver to communicate with the pit crew through the use of a very simple Push-To-Talk (PTT) button for radio, or just talking via Bluetooth.
The pit crew also have a radio or Bluetooth unit and a headset with microphone and speakers to talk back.
Positives of each system:
2-way radio – Great transmission range (half mile or more), compatible with other radio makes, lots of accessories available, Very easy to set up and use.
Bluetooth – Simple operation, very clear audio, no buttons to press, no external wires to contend with.
Negatives of each system:
2-way radio – Can get interference from other users if on same channel. Wires and transmit buttons can be a distraction.
Bluetooth – Limited range (1 kilometre at most), little compatibility between makes and models so you must use compatible kit.
