What is the 1/3 rule in scuba diving?
The 1/3 rule, also called the Rule of Thirds, states that you should use one-third of your air supply to descend into the water, one-third for the actual dive, and save one-third for your ascent back to the surface. In technical diving, the 1/3 Rule ensures divers have enough gas for the descent, return, and emergencies. It divides the total gas supply into three parts: one-third for the descent and exploration, one-third for the return, and one-third as a reserve, enhancing safety in challenging environments.The Rule of Thirds is a guideline used by scuba divers to manage their air supply effectively throughout a dive. It involves mentally dividing one’s breathing gas supply into three equal parts. One-third for the outward journey, one-third for the return journey, and one-third as a reserve or emergency supply.Shallow Diving (0-12 meters / 0-40 feet): Ideal for beginners and snorkelers, dives for basic courses or diving with children. Intermediate Dive (12-18 meters / 40-60 feet): Standard depth for recreational diving. Deep Diving (18-40 meters / 60-130 feet): Maximum limit for Open Water certified recreational divers.The 120 Rule is a quick mental math tool recreational divers use, mainly for planning repeat dives in a single day within moderate depths. Its core is simple arithmetic: for any single planned dive, your maximum depth in feet plus your planned maximum bottom time in minutes should ideally equal 120 or less.
