It seems like there might be a slight error or missing context in your question. If you are asking about the typical duration of a scuba dive, it can vary significantly based on factors such as the type of dive, the dive site, and the diver's experience level. Recreational scuba dives, for example, often last between 30 minutes to an hour, depending on factors like the depth of the dive, air consumption, and the specific dive plan. Technical dives or dives with specific purposes may have longer durations, but they also require additional training and equipment. If you meant something else by "how many years does scuba diver," please provide more context or clarify your question, and I'll do my best to assist you.
Most sport divers do not venture much below 100ft. Preparations for dives below this depth are more involved and bottom time is severely limited.
In the Olympics, a 'gainer' refers to a type of diving. 'Gainer' dives are also known as 'reverse' dives, and involve the diver performing somersaults in the air while diving.
Surface, shallow-water, deep-water and saturation dives in SCUBA - to name a few.
diver's short name or code for your 'average' dive trip on a dive boat - 2 dives, each separated by an approximate 1 hour SIT (Surface Interval Time), usually on 2 different dive spots.
Gas loading needs to be considered after diving before complete outgassing has occurred in any future dives, airplane travel with cabin pressures below 1atm, or in any case where the diver's altitude may change to the point that air pressure is significantly reduced below 1atm. (So no mountain climbing until you're clear!).
It depends on how deep the diver goes, and what air blend the diver is breathing. There are dive tables that state how long a diver can stay at a certain depth before requiring decompression. The basic recreational diver typically breathes either air or Nitrox. There are separate dives tables for air and Nitrox.
