What is the 120 rule in scuba diving?
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. Think of a dive to 60 feet: under this rule, aim for 60 minutes max bottom time (60 + 60 = 120). While recreational divers may venture 30+ feet underwater and employ a method of slow ascent to prevent decompression sickness, the world of saturation diving is a different ball game. These professionals often work at staggering depths, sometimes reaching up to 1,000 feet.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.Total time = Tank capacity / Air per minute. Using an 80 cubic foot tank at 3,000 psi: A diver with a SAC rate of 0. With an 80 cubic foot tank, they’d have about 53 minutes of dive time (80 / 1.On the deepest working dives, at depths greater than 600 m, ambient pressure is greater than 6100 kPa and the divers breathe gas mixtures containing about 2% oxygen to avoid acute oxygen toxicity.
What is the scuba 1/3 rule?
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. 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.According to this rule, a diver should divide their gas supply into three equal parts: One-third for the descent and exploration phase. One-third for the return to the surface. One-third as a reserve for emergencies.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.
What are the two golden rules when scuba diving?

However, the biggest concern is getting crushed from the increasing weight of the water. The water pressure can suffocate you to death if you don’t take precautions.
