Be careful and read the competition rules BEFORE using handhelds at a competition for scouting. You could probably do it as long as you don't try to send anything between the stands and the pits by airwaves. However, cell phone use-and most likely handheld use- is usually frowned upon at the events. And walkie talkies--don't try it.
My point is that you need to be careful when using these devices.
