Many people use a SCUBA suit for diving. Sport divers, police divers and some Navy recovery divers.
Scuba - self contained underwater breathing apparatus
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

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.
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.
They can't survive without oxygen but they can survive with an oxygen mask that scuba divers use and with supply of oxygen of course .
