What is the 120 rule in diving?
The rule suggests that the depth of the dive (in feet) and the time spent underwater (in minutes) should not exceed a combined total of 120. The goal of this rule is to keep divers within a range where they can avoid serious risks such as nitrogen narcosis and decompression sickness. 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.Here’s how it works: Your max depth (in feet) + your bottom time (in minutes) should be less than or equal to 120. That’s it. So if you plan to dive to 60 feet, the rule says you shouldn’t stay down longer than 60 minutes.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.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.

Are scuba divers in demand?
Are commercial divers in demand? Commercial diving is a growth industry. Jobs in the field continue to stem from the need to maintain oil rigs and repair damages resulting mostly from hurricanes. Recent floods have led to additional demand for commercial divers to inspect and repair bridges, dams, and other structures. Commercial diving is a physically demanding job and it takes a person who is physically fit. Beyond age 45, divers are typically restricted from deep diving due to physiological concerns, so most companies like to see individuals entering the field no later than their mid-30s.
