What is the 120 rule in scuba diving?
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. For recreational scuba divers, most diving agencies recommend a maximum depth limit of 40 meters. This limit is in place for safety reasons, and diving within these boundaries is deemed relatively safe, provided recreational divers have the appropriate training and equipment.While it’s technically possible to experience scuba diving without certification through introductory programs like Discover Scuba Diving or resort dives, full certification offers a world of deeper, richer, and safer underwater experiences.Master Scuba Diver: The highest non-professional certification, the Master Scuba Diver level recognizes divers who have completed various specialty courses, demonstrating a broad range of skills and experience.The advanced open water diver certification, or, if you do not have time to complete your full certification, your deep adventure dive will open up the world of deeper diving, with your maximum diving depth becoming 30m. This is also the depth limit for Rescue divers and divemasters.How deep do you go? With the necessary training and experience, the limit for recreational scuba diving is 40 metres/130 feet. Beginning scuba divers stay shallower than about 18 metres/60 feet.
What is the scuba 1/3 rule?
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.
What is the golden rule of scuba diving?
Never hold your breath. This is undoubtedly by far the most crucial of all safety rules for diving because failure to adhere could result in fatality. If you hold your breath underwater at the depths at which scuba divers reach then the fluctuating pressure of air in your lungs can rupture the lung walls. Divers need to have healthy lungs and a strong heart to handle the pressures of diving and the physical exertion involved. Individuals with heart problems, such as arrhythmias or a history of heart attacks, should avoid diving, as the underwater environment can exacerbate these issues.A person with heart trouble, a current cold or congestion, epilepsy, asthma, a severe medical problem, or is who under the influence of alcohol or drugs, should not dive.
