BLUETOOTH:
The driver has a Bluetooth helmet mounted headset with microphone and speakers. The crew have a headset also equiped with same Bluetooth module and they communicate without pressing any buttons or wires. The audio clarity is very good and they are easy to use. The down-side is that Bluetooth is a "line of sight" signal - if you cannot actually see the driver, you cannot communicate, so tracks such as Teeside where the drivers are not in view for long periods, means the communication time is limited. Also, there are pairing issues with multiple drivers to the crew.
IntaRace offer in-ear speakers for these systems as well as helmet speakers.  These systems are perfect for coaching young drivers.

Radio - Kart Based:
The radio and transmit button are mounted to the kart and each driver simply plugs their helmet headset into the system. The Crew have a headset with a radio on the same channel. To communicate, simply press the transmit button on the steering wheel or the crew headset. Radio based systems will still operate when the driver is out of sight and our high power batteries will last the full 24hrs of an endurance race on a single charge. These are the best solution for all kart racing disciplines.

Radio - Driver based:
The driver is equipped with a 2-way radio and headset that actually looks and fits like a Bluetooth helmet unit!  The driver operates the radio unit with a Bluetooth transmit button that simply straps to the steering wheel with a velcro strap. The Crew have the same radio headset as above 2-way radio systems.

All our systems have noise cancelling microphones and either helmet speakers as standard or (optional) in-ear speakers. The in-ear speakers protect the driver from hearing damage (especially important for young drivers) and ensure they hear the pit radio clearly.
