COMFORT. PERFORMANCE. STYLE. AND VALUE.

Our most popular regulator, the Atomic Aquatics B2 system combines the signature second stage design and materials of the T3 with a Chrome-plated Brass first stage. The result is an incredibly high-performance regulator system that is approachable for every diver and every budget.

LIGHTWEIGHT WITH HEAVYWEIGHT PERFORMANCE

The B2 weighs just 2.5 pounds (yoke version), just 9 ounces more than the super lightweight T3.
