How often must depth gauges be checked for accuracy?

Depth gauges are critical tools for SCUBA divers as they provide essential information about the depth at which a diver is operating. Regular checks for accuracy are necessary to ensure that divers can rely on these readings for safety and operational planning.

Testing depth gauges every 18 months or when inaccuracies are suspected is a sound practice because it balances the need for accuracy with practical considerations. It allows for sufficient time intervals between checks while also ensuring that divers can address any issues that arise if a gauge is suspected of malfunctioning. This approach helps to ensure that divers can perform safely without unnecessary frequency of checks that could lead to equipment neglect or build-up of complications.

Utilizing a timeframe of 18 months recognizes the longevity and reliability of modern equipment, while also maintaining a benchmark for safety. It permits divers and supervisors to remain confident in their instruments without the need for overly frequent checks, making it both a practical and effective interval for ensuring equipment integrity.
