Yes, you're right; it was CoxBox. For anyone who hasn't seen one. It looks a bit like a classic "James Bond" style bomb - LCD, switches and a few wires. It's even packed in a suspicious-looking black case.
They are used in rowing eights as the boat is quite long and it's hard for everyone to hear what the cox is saying. I have the microphone and the rowers have loadspeakers under their seats. Of course it would be even better if they actually did what I told them, but that's another problem...
