Unfortunately, the driver does not have a pit board of his own-and if he or she did, it would probably blow out the window. So a pit board is a great way to get old information. Pit boards also can't relay tactical data, and their information is very public. That would be a great place to set up a pass. Basically, pit boards are limited in the amount of information that they can convey.
Radios are also useful for learning the location of accidents.
When coupled with a scanner that can monitor the track officials' frequency, the crew can use radios to learn the location of incidents and relay them to the driver. And if the driver is involved in one of those incidents, the crew can instantly determine whether or not to start dividing up his personal effects. Well, we'd suggest you call one of the radio professionals advertising in this publication. The crew radio will have a headset so the crew chief can hear over the din of the pits, and the driver radio will have a harness that will connect to the driver's helmet. The helmet-mounted speakers usually don't give you very good clarity.
