My wife and I like to go scuba diving on occassion
I love scuba diving! It's a form of underwater diving where the diver uses a self-contained underwater breathing apparatus called a scuba which is completely independent of surface air supply, to breathe underwater.
Do you happen to know when scuba diving was first done? :D
Well, in 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 covered 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.
Oh? That's neat! I did not know that. Do you happen to know if there is a particular area well known for scuba diving?
I'm not sure, but the history of underwater diving starts with freediving as a widespread means of hunting and gathering, both for food and other valuable resources such as pearls and coral.
Cool. Is there anything else interesting you can tell me?
Oh yes and it's all about safety! I must tell you that the safety of underwater diving depends on four factors: the environment, the equipment, behaviour of the individual diver and performance of the dive team.
Neat! Anything else you want to say? I'm all ears :D
Diving safety
The safety of underwater diving depends on four factors: the environment, the equipment, behaviour of the individual diver and performance of the dive team. The underwater environment can impose severe physical and psychological stress on a diver, and is mostly beyond the diver's control. Equipment is used to operate underwater for anything beyond very short periods, and the reliable function of some of the equipment is critical to even short term survival. Other equipment allows the diver to operate in relative comfort and efficiency. The performance of
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
