The Atomic B2 Regulator is one of the lightest and most comfortable scuba regulators, perfect for both local dives and travel adventures. Built with premium materials, it offers reliable performance, durability, and smooth breathing on every dive.
The first stage is made from chrome-plated brass and 316 stainless steel for strength and corrosion resistance. Its Balanced Jet Seat piston delivers consistent airflow and is Nitrox ready up to 40%. With two fixed HP ports and five LP ports on a swivel cap, the setup is versatile and easy to customize.
The second stage features lightweight titanium construction for comfort and durability. Atomic’s Automatic Flow Control (AFC) ensures effortless breathing at any depth, while the Comfort Swivel hose reduces jaw fatigue. A dual-silicone mouthpiece and advanced airfoil design make every breath feel natural and smooth.

5 out of 5 stars
I have been diving for almost 30 years, and have used quite a few different regulators, from Sherwood, US Divers, Scubapro,Mares, and many others. This is by far the most comfortable and easiest breathing unit I have ever used.
