Scuba diving is an exciting and fantastic activity that can be practiced by everyone, anywhere in the world. It follows that regulators, being the most important piece of equipment to a scuba diver, need to adapt to an enormous range of different environmental conditions, individual breathing behaviors and personal preferences. Therefore, SCUBAPRO offers a large choice of various first and second stage regulators which can be combined to make up numerous kinds of regulator systems. Some of these regulator systems will work more efficiently than others depending on diving conditions and scuba diving behavior, as their mechanisms and designs teamwork better together. To support your decision in choosing the right regulator, SCUBAPRO proposes these selected systems, which fulfill the needs of different ranges of diving and environments perfectly.

WORK OF BREATHING
Work of breathing depicts the cycle of inhalation and exhalation energy expended to breathe from a regulator.
Inhalation is the effort to open valve and maintain airflow.
Exhalation is the effort to push exhaled breath through the regulator casing and past the exhaust valve.
So, the lower the better. SCUBAPRO regulators exceed WOB standards of both the US Navy and European CE.
EN250 standards for a cold water regulator mandate a limit of 3.0 Joules per Liter
at a depth of 50m, with 300bar of tank pressure, 2° to 4° C water temperature and
25 breaths per minute.
