It is difficult to determine a precise depth at which a diver will be crushed, but most recreational divers rarely go beyond 130 feet. On the other hand, commercial divers can use wetsuits to reach depths of up to 2,000 feet. Some recreational divers have even gone as deep as 1,000 feet and survived without any problem. Deep diving is any dive that goes beyond 20 meters (60 feet).
The deepest point ever reached by man is 35,858 feet below the surface of the ocean, located in the Challenger Abyss of the Mariana Trench under the Pacific Ocean. To go even deeper, you would need a shovel. The record for the deepest dive without oxygen was set at 831 feet (253.2 meters), but the diver suffered a brain injury while climbing back up. You can also take a specialized course in deep diving where you will be trained to dive at a depth of up to 40 meters (140 feet). As much as a human can dive at about 2000 feet (and that too with a special atmospheric suit), attempting a 12,000 foot dive is an impossible feat.
Eagle's Nest is considered the Mount Everest of diving and one of the most complex dive sites in the world. With more training, you can obtain the advanced open water diving certification that will allow you to dive to a depth of 30 meters (about 100 feet).The PADI (Professional Association of Dive Instructors) estimates that recreational divers can dive to a maximum depth of 130 feet. You can dive to a maximum depth of 30 meters with the Advanced Open Water certification, which requires additional training (around 100 feet). Scuba divers sail for a few days and live on a high-pressure boat or barge while not diving.
For very deep dives, you need a special gas mixture to help you breathe comfortably and combat the effects of nitrogen narcosis when you dive. Knowing how far humans can dive in the ocean is much more crucial for deep dives than for beginners. Diving without diving equipment is not recommended, but many daredevils and diving enthusiasts have taken up the challenge of free diving and have set world records. Some deep dive sites may lead you to wrecks or may require you to use enriched air to extend your dive time. Diving institutions such as PADI offer certifications for diving in caves, exploring shipwrecks, etc., to enrich your diving experience. They are designed for shallow diving and their main purpose is to increase the diver's decompression limit.
Therefore, you can also consider enrolling in other specialized courses, such as wreck diving, maximum performance buoyancy and enriched air diving. To dive at such great depths, you'll need a special mix of gases in the air supply to prevent the narcotic effect of compressed nitrogen from taking hold.
