Divers carry gauges that display information such as remaining cylinder pressure, current depth, elapsed dive time, and direction of travel.

These gauges are usually held by a console that's attached to the regulator by a high-pressure hose. This minimizes confusion over where your gauges are located, and also helps prevent misplacing or forgetting your gauges.

Some divers prefer to wear gauges on their wrist, so most gauges are available with wristbands as an option.
