Recreational diving is an exciting adventure sport that allows you to explore the depths of the ocean and discover incredible things. With basic open water certification, a diver can dive to a maximum depth of 18 meters (about 60 feet). With more training, you can obtain the advanced open water diving certification that will enable you to dive to a depth of 30 meters (about 100 feet). According to the PADI (Professional Association of Dive Instructors), the estimated deepest depth that recreational divers can reach is about 130 feet, but their time to explore is very limited due to water pressure and the ingress of compressed air. Technical diving involves multiple tanks, both on the diver and on the ascent line.
The lack of technology to help divers dive to such depths exposes them to unpredictable dangers, such as shark attacks. They can dive to those depths because their body contains a large volume of blood and a greater amount of myoglobin (a protein that stores oxygen). The average depth for technical divers is 130 to 330 feet, depending on the dive site and other conditions that may affect the dive. For diving above 100 feet, it is highly recommended to take a specialized deep diving course in order to learn how deep diving affects the body and how to properly prepare for an ascent from depth. Diving institutions such as PADI offer certifications for diving in caves, exploring wrecks, etc., to enrich your diving experience.
This syndrome can be reduced by breathing mixed gases and descending more slowly, but it is still one of the limitations of the depth at which you can dive. For example, Trieste was the first to reach the Challenger Deep and has since held the record for the deepest dive. He had been a professional diver for about 17 years and had spent 4 years preparing for his record-breaking dive. Beluga whales can dive to depths of between 400 meters (1,312 feet) and 647 meters (2,122 feet) below sea level, but wild belugas can go even further. It's important to keep your abdomen warm while you dive because blood is normally sent to the heart and brain. Therefore, depths greater than 130 feet are not recommended for recreational diving.
