We started using radios a year ago and I find they make a big difference. They greatly reduce your chances of being arrested. You can post a lookout further away, giving the person trying to find a way in a longer period of time to bail if somebody turns up. You can buy a short range licence free radio and earpiece for a tenner, making them disposable if need be. We use them for about half the new places we hit.
Whistles - the poor man's radio. Blow a whistle and everyone else bails.
