Scuba Equipment
Scuba equipment, purchased new, extends diving time. As opposed to
used or rental equipment, new gear extends time on the lake or ocean
floor, enhances dive comfort and is more enjoyable.
Some divers are using a piece of scuba equipment known as a rebreather.
The diver breathes in from the set, and then breathes back into the
set where the exhaled carbon dioxide is processed to make it fit to
breathe again. This type of scuba equipment is actually older than open-circuit
sets, but they are used less often.
Scuba equipment provides a supply of air and other breathing gases
from a high pressure diving cylinder which is worn on the diver’s
back. The rebreather set and the open-circuit set both require a demand
regulator to control the amount of gas that is breathed. Some rebreathers
only have a constant-flow regulator.
