Can I dive without a computer?
Bottom Line: If you don’t use a dive computer, you must calculate your dives the good old fashioned way[1] to avoid the danger of decompression sickness (DCS). A safety stop is a pause that scuba divers make while they are returning to the surface after a dive. This short break usually occurs at a depth of 5 metres for between three and five minutes and helps the diver’s body decompress from the effects of the dive. This is a critical step in safe diving practices.How deep can you dive without decompression? Practically speaking, you can make no stop dives to 130 feet. While you can, in theory, go deeper than that and stay within no stop limits, the no stop times are so short that well within limits is essentially impossible.
What is the safest depth to scuba dive?
For recreational scuba divers, most diving agencies recommend a maximum depth limit of 40 meters. This limit is in place for safety reasons, and diving within these boundaries is deemed relatively safe, provided recreational divers have the appropriate training and equipment. 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.Step 6: Open Water Dives Your first two dives will be to 12 meters/40 feet or shallower. The maximum depth allowed for your two final dives is 18 meters/60 feet.While recreational divers may venture 30+ feet underwater and employ a method of slow ascent to prevent decompression sickness, the world of saturation diving is a different ball game. These professionals often work at staggering depths, sometimes reaching up to 1,000 feet.In recreational diving, and according to major agencies like PADI and Scuba Diving International (SDI), any dive beyond 60 feet (18 meters) but not exceeding 130 feet (40 meters) qualifies as deep-water scuba diving.
