Product Description

Atomic B2 Regulator w Free Octo

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.

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

Second Stage:

  • All-Titanium second stage construction same as Atomic T2
  • Patented Atomic Seat Saving Orifice
  • Patented Atomic Automatic Flow Control (AFC)
  • Rapid adjustment knob for manual second stage de-tuning in special situations

  • A new high-flow second stage case that significantly lowers breathing effort at any depth from shallow water to beyond the limits
  • Dual material second stage cover enables entire front to be used for purge
  • Dual silicone comfort fit mouthpiece with tear-resistant bite tabs
  • 2 year/300 dive service interval
  • Limited Lifetime Warranty – not contingent on proof of service

Thank you for the great review

By Michael Carvalho on March 17, 2021

I've been diving this regulator for over 10 years and love it. I brought 2 with me to Antarctica and they performed flawlessly. I'm putting 75 dives a year on them in a variety of conditions from the Gulf of Maine to the Gulf of Mexico, wreck diving and spearfishing. Always reliable. You're paying for superb quality and it is well worth it.

Thank you for the review! We are happy to hear you were pleased with your gear. Please let us know if there is anything else we can assist you with in the future! Happy diving!
