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. Scuba diving involves using specialized equipment like a regulator, buoyancy control device (BCD), and air tank. Without proper training, it’s easy to misuse this equipment, which can lead to malfunctions, accidents, or even drowning.Consider the ABCs of diving: airway, breathing and clearing, on every dive. Even the most experienced divers can have an issue if their eyes, ears, nose or mouth unexpectedly come into contact with water. At the surface, make sure you inflate your BC and are positively buoyant.We’re talking here about recreational open-circuit scuba diving. And, no, it is not a “license. Instead, you will get a certification card, commonly referred to as a C-card, that attests you have done some training with a scuba diving instructor.This is one of the most common questions we get from people interested in diving or snorkeling for the first time. The answer is a big YES! All introductory dive and snorkel programs are perfectly safe and specially designed for non swimmers but any type of diving certification would require basic swimming skills.scuba diving requires more preparation than snorkeling does. You need to undergo formal training to participate in diving activities. While it may seem complicated at first, learning to scuba dive is easier than you think. You can become a certified diver in just a couple of weeks.
What is the 120 rule in 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. The need to do decompression stops increases with depth. A diver at 6 metres (20 ft) may be able to dive for many hours without needing to do decompression stops. At depths greater than 40 metres (131 ft), a diver may have only a few minutes at the deepest part of the dive before decompression stops are needed.The depth to which a non-certified individual can dive is significantly restricted. Most dive centers and resorts allow non-certified individuals to experience scuba diving under the direct supervision of a certified instructor, typically limiting dives to a maximum depth of 12 meters (40 feet).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).Technical diving is a more complex, and challenging, form of scuba diving. Technical divers rely on specialized training, equipment, and mixed gases to safely descend beyond the recreational limit to depths that can exceed 90 meters (300 feet).
