Frequently Asked Questions

What do divers use to communicate?

Divers use a variety of communication systems depending on the nature of their dive and the environment. For shallow water and close proximity, divers often use simple hand signals or underwater slates for written messages. In more complex or deeper dives, divers might use through-water electronic communication devices, which allow voice transmission between divers and between divers and surface teams. Hard-wired communication systems are also used, particularly in commercial diving, providing a reliable and clear communication link.
