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. Navy SEAL dive training occurs first at the Second Phase (Dive) of BUD’s and it’s the Combat Divers Coarse. SEALS don’t usually dive deep but can push too 100 to 130 feet but diving is mission specific. PADI gave me more technical diving related too instruction and safety as well as operating in the civilian sector.Recreational divers can dive as deep as 130 feet (40m). Although, this exact depth does not apply to all recreational divers as it all depends on the age and training of the divers. The maximum depth of a certified PADI Scuba Diver is 40ft (12m) and the maximum depth for a certified PADI Open Water Diver is 60ft (18m).
What is the golden rule of 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. However, scuba diving can also lead to decreased lung function due to factors such as hyperoxia, development of decompression gas bubbles, hypothermia, and mouth breathing with dry, cold, compressed air. These factors can trigger airway damage, leading to small airway obstruction (skogstad et al.
What is the 1 3 rule in cave diving?
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. 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.For divers following the rule, one third of the gas supply is planned for the outward journey, one third is for the return journey and one third is a safety reserve.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.
