My wife and I like to go scuba diving. Breathing underwater and relying on the breathing apparatus makes me a bit nervous, but it's so worth it
I have never been scuba diving, is it hard or complicated? Do you use oxygen?
Yah the compressed air is the SCUBA (self contained underwater breathing apparatus). You have to take courses before you can do it safely
Do you scuba dive commercially or recreationally?
the 16th and 17th centuries diving bells became functionally useful when a renewable supply of air could be provided to the diver at depth, and progressed to surface supplied diving helmets - in effect miniature diving bells covering the diver's head and supplied with compressed air by manually operated pumps - which were improved by attaching a waterproof suit to the helmet and in the early 19th century became the standard diving dress.
Limitations in mobility of the surface supplied systems encouraged the development of both open circuit and closed circuit scuba in the 20th century
Scuba diving
Scuba diving is a mode of underwater diving where the diver uses a self-contained underwater breathing apparatus (scuba), which is completely independent of surface supply, to breathe underwater. Scuba divers carry their own source of breathing gas, usually compressed air, allowing them greater independence and freedom of movement than surface-supplied divers, and longer underwater endurance than breath-hold divers. Although the use of compressed air is common, a new mixture called enriched air (Nitrox) has been gaining popularity due to
