SCUBAPRO teams its high performance first stage with its new air balanced second stage. The MK25 EVO offers excellent resistance to freezing, superb inhalation sensitivity and instant delivery of air on demand. The new S620 Ti embraces the best features of SCUBAPRO's renowned S600 in an upgraded, state-of-the-art design. Smaller and lighter than the S600 but using the same-sized diaphragm, the S620 Ti delivers effortless airflow under all dive conditions. The full titanium inlet tube is ultralight, the large purge button improves water circulation, and the new exhaust tee increases performance while directing bubbles out of the field of view. In all water temperatures, in all dive conditions, this new reg system is a winner.

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.
Virtually identical performance as the T2 with a Brass First Stage
The B2 gives divers an 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.
