What is the deepest a scuba diver ever went?
Metres deep gabr holds a guinness world record for the deepest scuba diving in history. It took approximately 12 minutes for ahmed to reach his record depth of 332.

It was achieved by saddam killany in dahab, egypt on the 11th of november 2020. This historic feat took place from the 5th to the 11th .
What is the 120 rule in scuba diving?
The 120 Rule is a quick mental math tool recreational divers use, mainly for planning repeat dives in a single day within moderate depths. Its core is simple arithmetic: for any single planned dive, your maximum depth in feet plus your planned maximum bottom time in minutes should ideally equal 120 or less. 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. The goal of this rule is to keep divers within a range where they can avoid serious risks such as nitrogen narcosis and decompression sickness.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.Scuba diving is a high risk activity that can be enjoyed extremely safely, provided individuals dive within their limits. If you choose to, you can make diving as dangerous as you like.Some recreational divers have descended to depths of 1,000 feet and beyond and survived the experience without any problems. However, the biggest concern is getting crushed from the increasing weight of the water. The water pressure can suffocate you to death if you don’t take precautions.A person with heart trouble, a current cold or congestion or who has epilepsy, asthma, a serious medical problem, or who is under the influence of alcohol or drugs, should not dive.
What is the 1/3 rule in scuba diving?
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. 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.
Is scuba diving a high risk activity?
Despite the inherent risks, scuba diving is relatively safe when compared to other recreational and competitive sports. In the USA, annual fatality rates associated with scuba diving have been reported to average 16. Scuba diving requires heavy exertion. The diver must be free of significant cardiovascular and respiratory disease. An absolute requirement is the ability of the lungs, middle ear, and sinuses to equalize pressure. Any condition that risks the loss of consciousness must disqualify the applicant.Individuals should not dive if they have cardiac disease that might result in incapacity underwater (e. IPO (e. DCS (e.The most frequent known root cause for diving fatalities is running out of, or low on, breathing gas, but the reasons for this are not specified, probably due to lack of data. Other factors cited include buoyancy control, entanglement or entrapment, rough water, equipment misuse or problems and emergency ascent.Scuba diving typically involves moderate intensity physical activity, but situations can occur that require high-intensity activity. In addition, scuba diving challenges the cardiovascular system in a variety of ways that may be life-threatening for individuals with heart disease or a low capacity for exercise.
