Shop an in-stock Atomic B2 regulator with the titanium second-stage feel Atomic is known for—without the full all-titanium T3 price. Gulf Coast Scuba carries the Atomic Aquatics B2 yoke sealed (Black) ready for Houston pickup or U.S. shipping.

Sealed brass first stage + titanium second stage

This sealed first stage uses chrome-plated brass with 316 stainless details and Atomic’s balanced Jet Seat high-flow piston to help limit silt and sand contamination. Port layout: 2 HP fixed and 5 LP on a swivel cap. The second stage is all-titanium like the T3—pneumatically balanced—with Automatic Flow Control (AFC), a Rapid Adjustment Knob for surf entries or octo use, and the titanium Seat Saving Dynamic Orifice. Hose Comfort Swivel is polished 316 stainless with Black PVD. Nitrox-ready up to 40%.

Travel weight vs the T3

According to Atomic, the yoke B2 weighs about 2.5 lb—only about 9 ounces more than the T3—so you keep most of the travel advantage. Atomic recommends service every 2 years or 300 dives, with Atomic’s limited lifetime warranty approach on metal corrosion (not contingent on proof of service, according to Atomic).

Who the B2 is for

Divers who want Atomic performance and a titanium second stage, but prefer brass-first-stage value over the T3. Ready for full titanium? See our in-stock Atomic T3 yoke sealed regulator.
