What is the 120 rule in scuba diving?
The rule advises that the dive depth (in feet) in addition to the time a diver spends underwater (in minutes) should add up to no more than 120. The purpose of this rule is to help scuba divers to avoid serious dangers such as nitrogen narcosis as well as decompression sickness by keeping them within a safe range. 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 advises that the dive depth (in feet) in addition to the time a diver spends underwater (in minutes) should add up to no more than 120.

What is the 1/3 rule in diving?
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. Divided Gas Supply: The 1/3 rule 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. Emergency Preparedness: The reserved third ensures that divers have enough gas to manage unexpected situations or emergencies.The Rule of Thirds is a guideline used by scuba divers to manage their air supply effectively throughout a dive.
