Diving gases which are used (in order of frequency in everyday use):
The types of gas that a scuba diver can use are nitrox gas and pressurized, filtered air. These are the gases that they can use. The most frequently used gas for recreational diving is filtered air, but nitrox is used for tech diving, and for deep depth diving.
Depending if the person is nitrox certified or not the gas in the tank is compressed air or if nitrox certified the gas will be a mix of nitrogen and oxygen with the mix marked as a percentage of O2.
the same thing everyone breaths, oxygen
Scuba - self contained underwater breathing apparatus
water proof ones
scuba divers use pressure meter because the deeper down you go the more pressure builds upAdditiona depth gauge or a dive computer
Scuba Divers use a Sonar to find treasure or a hidden ship.
For oxygen masks for firefighters, scuba divers etc
This is a dive using scuba equipment you are used to seeing. It is where you breath from a scuba cylinder and exhale all the gas you breathed as bubbles. Since you are not recycling or rebreathing any of the gas, the circuit is open. Closed circuit or semi-closed circuit is where divers use "rebreathers" and rebreath the majority of their gas. 100% of the gas can never be rebreathed, so a very small amount is exhaled as bubbles.
In recreational diving, most divers use compressed air (as in the normal air we breather at the surface). Some divers are also trained to use special gas mixes called Nitrox which have a higher oxygen content and lower Nitrogen. Professional (or commerical) divers tend to use more advance mixes such as Heliox or Trimix which combine Oxygen, Nitrogen and Helium.
Divers use substances with high density (ie. lead) to help them sink, and substances with low density (ie. air) to help them float. That way they control their bouyancy.

Scuba divers engage in underwater activities using self-contained underwater breathing apparatus (scuba) to explore marine environments. Here are some common activities that scuba divers participate in: Recreational Diving: Many scuba divers engage in recreational diving for enjoyment and exploration. This includes diving in coral reefs, exploring underwater caves, and observing marine life. Certification Courses: Scuba divers undergo training and certification courses to learn proper diving techniques, safety procedures, and how to use scuba equipment. Certification levels range from basic open water diver to advanced and specialized certifications. Underwater Photography and Videography: Some scuba divers specialize in underwater photography or videography to capture the beauty of marine life, coral reefs, and underwater landscapes. Research and Conservation: Scientific divers use scuba equipment to conduct underwater research, monitor marine ecosystems, and contribute to conservation efforts. They may study marine biology, ecology, or archaeology. Wreck Diving: Wreck diving involves exploring underwater shipwrecks or sunken structures, offering a unique perspective on maritime history and providing habitats for marine life. Technical Diving: Technical divers undergo additional training to explore deeper depths, conduct dives with extended bottom times, and use specialized equipment. Technical diving may include cave diving, deep diving, and wreck penetration. Search and Recovery: Some scuba divers are trained in search and recovery techniques, assisting in the retrieval of lost items or conducting underwater searches for missing persons. Public Safety Diving: Public safety divers, often part of emergency response teams, use scuba equipment for tasks such as underwater search and rescue, evidence recovery, and inspection of submerged structures. Dive Instruction: Certified scuba divers may become instructors, teaching others how to scuba dive and guiding them through certification courses. It's important for scuba divers to follow safety guidelines, adhere to their training, and be aware of the environmental impact of their activities to ensure a safe and enjoyable underwater experience.
Sky divers use parachutes to jump from planes. SCUBA divers have difficulty searching Loch Ness because there are many inlets and lagoons, and many have so much sediment that the water is very cloudy.
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.
