There will be air left in the tank. But it is not under enough pressure to come out of the bottle and into your lungs. There may actually be enough air to 'hiss' out once you get to the surface because it is no longer subject to the pressure of the water.
recreational diving is usually done with 3000 psi of air in a certified SCUBA tank
Different scuba gear types weigh different amounts. The oxygen tank is the heavy part of the scuba diving gear.
Swimming with an aqualung (also known as a scuba tank or scuba cylinder) and flippers is commonly referred to as "scuba diving." "Scuba" stands for "self-contained underwater breathing apparatus." In scuba diving, divers use specialized equipment, including a scuba tank containing compressed air or other breathing gas, a regulator to control the airflow, a buoyancy control device (BCD), and flippers (also known as fins) for underwater propulsion. Scuba diving allows individuals to explore the underwater world, observe marine life, and visit underwater environments at various depths. It is a popular recreational activity, as well as a professional and scientific endeavor. Scuba diving requires training and certification to ensure safety and competence in the use of the equipment and adherence to established diving procedures.
The vest is simply called a scuba vest. It's to hold your air tank and regulators :)
With scuba diving, you are diving with an oxygen tank on your back and a regulator in your mouth. For SNUBA, there isn't an oxygen pack on your back, instead your oxygen supply is a long hose attached to a raft on the surface of the water.
You'll either have to hold your breath or have a SCUBA tank.
In reference to scuba diving, "SPG" stands for "Submersible Pressure Guage", which tells you how much air is in your tank so you can resurface before going too low on oxygen.
The numbers on a scuba tank reveal 3 things. Serial no. of the tank. Type metal. and the current hydro date.
the silly answer is you can store anything in a scuba tank that you can get in it!!. BUTthe serious answer is scuba tank were designed for compressed air and nothing else... using a scuba tank for natural gas is like driving around with a bomb in your car!!, the valves and collars of the bottles are not strong enough if there was a crash
a breathing tank! try it its fun! (underwater swimming)
You could buy your own portable diving compressor, my dive buddy has one, there not silly expensive . You must get fills from a compressor designed for diving (breathing) as the air is filtered and moisture removed.
Its not really scuba diving but its considered scuba diving. Also known as the hookah system. its when you have a gas powered motor pumping fresh air to the person or person's diving below, there can be up to four people diving off of one hookah system. the benefit of this system is that there is no decompression time and you can be underwater pretty much all day if someone fills the gas tank on the engine pumping air. but you are kinda tied down to something so i don't think its true scuba diving.
