Example of the Scuba Diver Insignia on a USMC service uniform.

In the communication used by scuba divers, the OK sign is specific in its meaning that "everything is OK" as regulated by the Recreational Scuba Training Council. Divers are taught to always use this sign and not the thumbs up gesture because the latter means that a diver needs to ascend. [ 12 ]
In scuba diving, the thumbs-up gesture is a specific diving signal given underwater, in which the diver indicates that he or she is about to stop his or her dive and ascend. This occasionally confuses new divers, who might automatically gesture thumbs-up when trying to indicate approval—actually indicating a desire to stop diving and to ascend.
