Tec diving, a.k.a. technical diving, involves
diving beyond the normal limits of recreational scuba diving.
Participating in tec diving requires additional experience,
training and (of course) equipment. In recreational diving you
use one scuba tank but tec divers typically wear twin
cylinders, plus one or more additional ones under their arms,
each with different gas blends. They usually have two or more
completely independent regulators and dive computers, as well as
other backups to regular dive gear. |
