DIVERS' HAND SIGNALS
UNDERWATER COMMUNICATION
We also communicate when diving, of course. Since we cannot speak to one another, we use hand signals to communicate underwater. These hand signals are the same worldwide, meaning we can converse with our buddy and our group at any time during a dive.
Here you can find the most important hand signals in diving:
