Scuba regulators, also called 'diving regulators', are vital for scuba divers to properly obtain oxygen from a tank. Regulators are available for purchase through diving specialty stores such as Prime Scuba, House of Scuba, and Divers Direct.
Divers (and others) call the compressed air cylinders used by divers tank(s) or SCUBA tank(s).
they need to know how long they can be underwater, and how deep they can go with the air in the tank.
Most SCUBA divers dive with compressed air, which is normal atmospheric air compressed into a scuba tank.
Scuba divers require increased air pressures in their air tanks while diving because the pressure on their bodies increases.
yes, basically you're just saying what scuba-divers do
They don't breathe normally on their own.They have to use pressure regulators to breathe naturally, overcoming the extreme pressure deep underwater.A snorkel and oxygen tank help the divers breathe when they are underwater.
Equipment changes depending on the location of the dive and purpose. Basic equipment include, wetsuit, fins, snorkel and mask, lead weight, scuba tank, BCD (Buoyancy Compensation Device), and Regulator.
Divers usually increase their density by wearing a weight belt (which contains lead weights). Some divers also rely, to a lesser degree, on using steel tanks, which are more dense than aluminum tanks. To decrease their density, divers put air into a Bouyancy Control Device (BCD). Some divers may also control bouyancy by putting air into a drysuit if they wear one. Whereas the increase in density created by the weightbelt is normally fixed, the positive bouyancy provided by the BCD can be varied throughout the dive. Usually a divers net density will decrease over the dive - a diver with a full scuba tank has about 4.5 lbs of extra weight (the weight of the gas) over a diver with an empty scuba tank.
they use an air tank they put a mouth piece in there mouth and breath through it i know this because i went diving before oh and one last thing you have to keep an eye on how much air you have
They either go to a dive shop or have their own compressors. An average 80 ci tank costs roughly $5usd to fill
Lightning can be harmful to scuba divers because it can strike the water's surface and potentially electrocute anyone in the vicinity. Thunder, on the other hand, is not harmful to scuba divers but can indicate the presence of a thunderstorm, which can lead to dangerous conditions such as strong currents and rough seas. It is generally advised for divers to avoid entering the water during a thunderstorm or if lightning is present.
