What is the 120 rule in scuba diving?
The 120 Rule is a simple guideline that helps divers like you plan safe and efficient dives. To be more specific, it focuses on managing depth and dive time. To illustrate, let me show you this sample: 120 minus your depth (in feet) = your maximum bottom time (in minutes). The 120 rule in scuba diving is a simple, yet effective guideline used to help recreational divers plan their dives and stay within safe limits. 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.For recreational scuba divers, most diving agencies recommend a maximum depth limit of 40 meters. This limit is in place for safety reasons, as diving within these boundaries is considered relatively safe, provided divers have the appropriate training and equipment.The 1/3 rule ensures you always have enough air throughout your dive. Do your best to control how much oxygen you consume and preserve one-third for each portion of your dive. Moreover, if you use too much of your oxygen during the descent and dive, you may not have enough to ascend safely to the surface.The 120 Rule is a simple guideline that helps divers like you plan safe and efficient dives.

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. Diving on a single breath of air reduces the volume of air in the lungs. This can cause swelling of the mucosal tissue (mucosal edema), bloating of the blood vessels (vascular engorgement), and even lung hemorrhage, resulting in lung squeeze injury.Diving does entail some risk. Not to frighten you, but these risks include decompression sickness (DCS, the “bends”), arterial air embolism, and of course drowning. There are also effects of diving, such as nitrogen narcosis, that can contribute to the cause of these problems.It is widely accepted that individuals who have suffered a pneumothorax should not scuba dive in most circumstance. There are rare exceptions, for example when prevented surgery has been performed to both sides of the chest.

As an PADI Open Water Diver, your certification is good for life. If you do not actively participate in scuba for an extended period of time, however, it’s a good idea to refresh your skills through the PADI ReActivate class.MOS Description The diver performs or supervises SCUBA or Surface-Supplied diving operations for underwater reconnaissance, demolition, port construction and rehabilitation, harbor clearance, ship’s husbandry, river crossing, hydrographic survey, and salvage operations to a depth of 190FSW.The PADI Open Water Diver certification is the most popular scuba credential available. It’s a common requirement for professional diving jobs, but many recreational divers pursue this credential, too.
Can you scuba dive to 300 feet?
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). 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.PADI (Professional Association of Diving Instructors) estimates that recreational divers can dive to a maximum depth of 130 feet. But they have a limited amount of time to do so before their health is jeopardized by the high water pressure and the inhalation of compressed air.It is also important to remember those who have lost their lives attempting to achieve this. Ahmed Gabr began preparing for his record-breaking deep dive many years earlier. The dive to a depth of 332.
