Questions 27-32

Ambient divers, unlike divers who go underwater in submersible vehicles or pressure-resistant
suits, are exposed to the pressure and temperature of the surrounding (ambient) water. Of all types
of diving, the oldest and simplest is free diving. Free divers may use no equipment at all, but most
(line) use a face mask, foot fins, and a snorkel. Under the surface, free divers must hold their breath. Most
(5) free divers can descend only 30 to 40 feet, but some skilled divers can go as deep as 100 feet.
Scuba diving provides greater range than free diving. The word scuba stands for self-contained
underwater breathing apparatus. Scuba divers wear metal tanks with compressed air or other
breathing gases. When using open-circuit equipment, a scuba diver simply breathes air from the tank
through a hose and releases the exhaled air into the water. A closed-circuit breathing device, also
(10) called a rebreather,filters out carbon dioxide and other harmful gases and automatically adds
oxygen. This enables the diver to breathe the same air over and over.
In surface-supplied diving, divers wear helmets and waterproof canvas suits. Today, sophisticated
plastic helmets have replaced the heavy copper helmets used in the past. These divers get their air
from a hose connected to compressors on a boat. Surface-supplied divers can go deeper than any
(15) other type of ambient diver.
