B2 (DIN)
Only 2 left in stock
The Most Awarded Atomic Regulator
The B2 gives divers a close alternative to the all-Titanium T2. The signature Atomic breathing performance is nearly identical. The B2 is ergonomically designed to be the world’s most comfortable second stage just like the T2. The key difference is the chrome-plated Brass body of the B2 first stage, which is more economical without sacrificing performance. That’s why the B2 has garnered more awards from independent tests and reviews than any other regulator on the market.
Why Brass & Titanium?
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.
