How often must divers check their regulators for functionality before a dive?

Every dive
Once a year
Before each season
Monthly

The correct answer is: Every dive

Divers must check their regulators for functionality before every dive to ensure their safety and readiness. The regulator is a crucial piece of equipment that reduces high-pressure air from the tank to a breathable pressure. Any malfunction could lead to serious underwater issues, including the inability to breathe, which can quickly become a life-threatening situation. Conducting this check involves not just a visual inspection for damages or wear, but also testing the regulator by inhaling to make sure it delivers air smoothly and consistently. This practice helps divers identify any problems with the equipment, such as leaks or blockages, which, if left unnoticed, could jeopardize their dive experience and safety. Regular checks before each dive are recommended irrespective of the season, as issues can arise unexpectedly, making this preventative measure essential for all dives. While other timeframes for checks might be part of an overall equipment maintenance schedule, pre-dive checks remain paramount for immediate safety.
