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% First stage ports: 2 HP fixed / 5 LP on swivel cap
