It depends on many variables, such as the time the diver stays at a particular depth, the temperature, level of diver exertion, diver's physiology, etc, etc. Dive tables or a dive computer is used to calculate how long it is safe for the diver to stay submerged. The primary limitation on dive duration/depth during a day is how much Nitrogen the diver has absorbed into his or her tissues. Exceeding the safe limits can cause decompression illness. These limits are only rough guidelines however, as some people are at higher/lower risk for decompression illness based on their physiology, level of heath and fitness, and other factors.
Most recreational divers rarely dive below 100 feet. The average depth for a dive is around 60 feet.AdditionThere is a difference between the average deepest depth of of dives in general and the average depth of a single dive. Most dives will have the deepest depth of around 60 feet, but the average depth of that dive will probably be more in the range of 30 feet since divers will start at one depth and usually continue the dive at shallower depths.
Depends on the environment. IE water temp, stinging creatures, etc.
There is no depth limit, so as deep as a diver can stay comfortably warm in that particular suit in the water temperature.
More friction acts on a diver when they dive because of the increased density of the water.
Its called a dive
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.
It's about 2.5 miles below the surface of the North Atlantic. That depth is far beyond where a diver can go, but specialized deep-sea submarines can visit the wreck site.
when u learn how to dive
a skin diver does not
A backward dive is a dive in which the diver faces away from the water when taking off, and lands facing backwards.
Saturation Divers also dive shallow water by the way, I have worked as a Sat Diver the past 6 years and I started like many going to a Dive school then working in the industry for a while, you have to start at the bottom, become a tender, tender/diver, diver, ect... all depends on what you want to do. Sat diving is used not mainly for depth it allows max depth through HeO2 satuaration but the main reason is to be able to work undersea for longer periods of time.... look up Commercial Dive Schools first... do that then take a few years as a diver in the industry, I attended INPP for my Sat Course.
