The signal 'Okay?' is used in diving communication primarily to indicate that everything is fine. When divers use this hand signal, they are essentially checking in with their buddy or the group to confirm that all parties are safe and feeling good about the dive situation. This non-verbal communication is essential in an underwater environment where verbal communication is not possible, and it helps reinforce safety and awareness among divers.

By establishing a clear understanding of this signal, divers create a reliable way to maintain communication about their well-being during a dive, which is critical for a safe diving experience. This fosters teamwork and mutual support among diver pairs or groups, as they can quickly check on each other's status without the need to resurface or remove their regulators.
