The first SCUBA (self-contained underwater breathing apparatus) was developed in the early 1940s by French divers Emile Gagnan and Jacques Cousteau (the latter went on to become a famous conservationist and filmmaker). It was patented in 1945 and called the Aqua Lung. ( BestReviews)
A good scuba regulator is a vital part of any dive gear, reducing the high pressure combination of helium, nitrogen, and oxygen in the tanks so it’s breathable by the diver. Not all regulators are the same, however, so we’ve put together a concise buyer’s guide to help those new to the sport decide which is best. We’ve also made a few recommendations at the end of this article. Our top pick is the outstanding Scubapro MK25 EVO/A700 Diving Regulator System, a combination that provides safety and easy breathing for experienced divers wherever they go and whatever conditions they encounter.

Scuba regulators are divided into first stage — which takes tank pressure down from a couple thousand pounds per square inch (psi) to around 140 psi — and second stage, the mouthpiece, which offers fine pressure adjustment for comfortable breathing. You may also have an octopus, or a standby second regulator for emergencies. Advertisement
The first-stage regulator is more complex. They are either diaphragm or piston operated.
