Can a human survive 1000 feet underwater?
Most recreational divers rarely dive deeper than 130 feet. But commercial divers can use atmospheric suits to descend to depths up to 2,000 feet. Some recreational divers have descended to depths of 1,000 feet and beyond and survived the experience without any problems. A diver at 6 metres (20 ft) may be able to dive for many hours without needing to do decompression stops. At depths greater than 40 metres (131 ft), a diver may have only a few minutes at the deepest part of the dive before decompression stops are needed.Stay within 300 feet (90 meters) of the diver down flag or buoy in open water and 100 feet (30 meters) when diving in rivers, inlets or navigation channels. Aim to surface within 150 feet (45 meters) of the dive flag.To prevent the bends, divers should: Ascend slowly, adhering to the recommended ascent rate of 30 feet per minute. Perform safety stops at 3-6 meters or 15-20 feet for 3-5 minutes during the ascent. Use dive computers or tables to plan dives within no-decompression limits.
