Atomic Aquatics B2 Sealed 1st Stage

Even though the use of multi-layer chrome plated Brass for the body of the first stage is a more conventional material choice... the performance of the B2 is truly superior to any other rival. Atomic designed our signature breathing performance into the B2 to give a diver the perfect combination of comfort, style and value. The main design difference? The total weight of the B2 is only 9 ounces more than the T2.

First Stage:

•  First stage materials are chrome-plated Brass and 316 Stainless Steel
• Atomic Jet Seat high-flow piston first stage
• Optional factory-sealed first stage to prevent outside contamination such as silt and sand and prevent freezing
• Nitrox ready for mixtures up to 40%
