ANSWER:Metal helmets are still in use by professional divers. Many consider the metal helmet to be safer than SCUBA gear.
Divers typically exit a submarine through a designated escape hatch or an external lockout chamber designed for underwater egress. Once the hatch is opened and verified clear of obstructions, divers don their gear and either swim directly out or use an attached platform that lowers them into the water. The process ensures safety and controlled conditions, allowing divers to surface effectively. After their mission, they return through the same route, ensuring all divers are accounted for before sealing the hatch.
Many people use a SCUBA suit for diving. Sport divers, police divers and some Navy recovery divers.
You can breathe underground by using submersible breathing aparatus similar to scuba gear used by divers.
Pearl divers typically use minimal equipment to enhance their underwater experience, such as goggles or masks for visibility, snorkels for breathing, and fins for better movement. In some cases, they may also utilize wetsuits for thermal protection and weight belts to help them descend. Advanced divers might use scuba gear, including tanks and regulators, to extend their time underwater and improve safety. Additionally, tools like nets or baskets can be used to collect oysters from the seabed.
Many scuba stores sell scuba diving cameras. Check a scuba gear stores in your area. This will allow you to compare cameras and get advise from fellow scuba divers.
Pearl divers traditionally used a technique called free diving, where they hold their breath while diving underwater to collect pearls. They typically trained to increase their lung capacity and learn to remain underwater for extended periods. Some divers also used weighted belts to help them dive deeper and return to the surface quickly. In modern times, divers may use scuba gear to breathe underwater more easily and safely.
Shamwow!
Divers use 21% Oxygen and 79% nitrogen while underwater. It results in the same exact air we breath on the surface.
To use it in that form, you could use it as a command. For instance, Dive into the water. To use it in another way, you would have to change the verb tense to "dove" or "diving" or something else like that.
No Specialized gear is needed to dive to the depths where the Lusitania rests. At 450 feet the wreck is not available to sport divers.
