; Beach master: A person on the beach who records when divers enter and exit the water. Typically used during scuba classes to keep track of the students, watch the gear, provide assistance when required.
; Buddy System: Two divers that dive together as a team for safety
; C-card: Certification card (proof of training or experience)
; Decompression Sickness: a disorder caused by bubbles of inert gases, such as the nitrogen in air, becoming trapped in the tissues, organs and blood vessels of the body causing symptoms ranging from rashes to death
; Decompression Stop: a pause during the ascent phase of the dive to allow safe release of inert gases from the tissues of the body and avoid Decompression Sickness
; Decompression Tables: Printed tables that provide divers with a way of avoiding Decompression Sickness by giving the maximum times that can be spent at depth, and by indicating the Decompression Stops and Surface Intervals needed for a particular depth and time profile to be carried out safely
; Delayed (surface marker) buoy: a small buoy on a line that divers inflate underwater to indicate their location to their boat
; Dive club: a group of people with an interest in SCUBA diving
; Dive Flag : Flag used by a boat to indicate that it has 'divers down'. Comes in two versions: the international (international code letter flag 'A', 
) and the American (red flag with white diagonal, 
), introduced by Ted Nixon in 1956. Boats must maintain a minimum distance away from the flag. Personal water craft pose a hazard to divers, and sadly few operators do know what a dive flag is. Some believe it is turn marker. If you observe a personal water craft operating to close to a dive flag contact the lake patrol.
; Dive Shop : supplier of dive equipment or training, or organizer of dive expeditions.
; Dive Tables: see Decompression tables
; Divemaster: A professional level diver who is in charge of the dive.
; Drift dive: a dive in a tidal current - gives the feeling of flying
; Fire Diving: An urban legend about a diver who is scooped up by a plane/chopper and dropped on a forest fire led someone to build a web site for the fictitious sport of Firediving
; Frogman: A slag term for scuba divers
; Hard Hat diving: A term for commercial divers. Refers to a modern fiberglass helmet or the old style brass helmet tethered divers wear.
; Log Book: List of the dives a diver has recorded for proof of experience.
; Rebreather: a device which reuses part of each breath. See linked article for more information.
; Navy SEAL: A highly trained military diver (http://www.sealchallenge.navy.mil/ )
; Navy Tables : A set of decompression tables developed by the US Navy. Used by early divers as a method to determine maximum time and depth.
; Night dive: a dive at night - many underwater animals are nocturnal or behave differently at night
; Saturation diving: a decompression regime used in commercial diving that allows divers to live work for weeks at a time where their tissues become saturated in high pressure gas.
; Shore diving: Scuba diving that starts from the shore line
; Skin: a lycra suit worn by a diver in warm water or under a wet suit.
; Surface interval: the time between dives. divers need to track this time interval for planning the next dive.
; Surface marker buoy: a small inflated buoy that divers tow when underwater on drift dives to indicate to indicate their location to their boat
; Time to fly: Divers must wait approx. 24 hours after the last dive before flying.
; Trash dive: a dive dedicated to removing trash from the underwater environment
; Wall diving : diving along the face of a vertical wall - requires good buoyancy control because there is no seabed to prevent the diver descending too deep
; Wreck diving : diving on wrecked ships
