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.The 1/3 rule, also called the Rule of Thirds, states that you should use one-third of your air supply to descend into the water, one-third for the actual dive, and save one-third for your ascent back to the surface.
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. The Rules of Scuba Diving: Never Hold Your Breath. Plan Your Dive. Dive Within Your Limits.Diving compressed gases (ie, scuba diving) can lead to two very serious medical conditions: Decompression Sickness (DCS), otherwise known as “the Bends,” and Pulmonary Over-Inflation Syndrome (POIS).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.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.
How deep can a beginner scuba go?
According to the PADI certifying agency, if you are doing your Open Water course and you are over 12 years old, you can dive to 18 meters/60 feet depth. If you are still a junior (from 10 to 12 years old), the maximum depth is 12 meters/40 feet. The brief response is no. There is no upper age limit for scuba diving. Many seniors finish the PADI Open Water Diver course (the entry-level course you need to take to become a certified scuba diver) and enjoy diving for years.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.While with adults the amount of acceptable risk has been quantified, the question remains a subject of debate when it comes to young kids. Most major dive organizations allow children as young as 8 to learn to scuba dive in a pool, while 10 years old is an industry-accepted minimum to become a certified scuba diver.One of the most frequently asked questions is whether seniors may be too old to learn to scuba dive. The brief response is no. There is no upper age limit for scuba diving.

What age to start scuba?
The short answer – you can start scuba diving at the age of eight years old. Most scuba diving certification institutions offer tailored lessons for young and eager divers, but there are some big Ts and Cs with this arrangement. 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.
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. 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).Based on personal experience, an average open-water certified diver using a standard aluminum 80-cubic-foot tank on a 40-foot dive will be able to stay down for about 45 to 60 minutes before surfacing with a safe reserve of air still in the tank.Why the 40 ft Limit. This is the depth for absolute beginners such as Discover Scuba Divers and Open Water students on dives 1 and 2. At this depth the NDL limit is over 2 hours, a new diver will use a tank of air in about 40 minutes at this depth.For a single no-decompression dive, the recommendation is a minimum preflight surface interval of 12 hours. For multiple dives per day or multiple days of diving, the recommendation is a minimum preflight surface interval of 18 hours.If you are learning to dive, or are just an ‘Open Water’ fun diver, you should dive no deeper than 18m. Advanced divers can go to 30m. Absolute beginners and novices are taken by a professional instructor to no deeper than 12m.
