What is the primary function of a dive slate?

A dive slate is primarily used for communication underwater. It serves as a tool for divers to convey messages, share information, or illustrate points when verbal communication is not possible due to the underwater environment. The slate is often used to write messages to buddies or to organize thoughts when giving guided dives, ensuring that important details can be shared effectively without the need for sound.

While keeping a log of dive times, recording water temperatures, and indicating dive locations are important aspects of diving, they are not the primary function of a dive slate. These activities typically involve different tools or methods, such as dive computers for logging times and temperatures, and GPS or underwater maps for dive locations. The focus of a dive slate is distinctly on facilitating communication between divers in the moment, making it an essential piece of equipment during dives.
