Frequently Asked Questions
Atomic B2 vs ST1: which should I choose?
Both breathe through the same titanium second-stage design as Atomic's T3 flagship. The difference is the first stage: the B2 uses chrome-plated brass — Atomic's value pick with flagship performance — while the ST1 is machined from solid 316 stainless steel with roughly twice the strength of brass and corrosion resistance approaching titanium, and it comes factory-sealed and freeze-protected as standard. Choose the ST1 for cold water, heavy use, or maximum durability; the B2 covers everything else for less.
How often does an Atomic regulator need service?
Every 2 years or 300 dives, whichever comes first — Atomic's officially published interval, and one of the longest in the industry (most brands require service annually or every 100 dives). Atomic also recommends a quick annual inspection by an authorized dealer between services. Over years of ownership, that service schedule is a real cost saving.
What is Atomic Aquatics' warranty on regulators?
A limited lifetime warranty for the original owner — and unusually, Atomic states the warranty is NOT contingent on proof of service. All titanium and metal parts are additionally warranted against corrosion for life. To activate it, register within 30 days of purchase, and buy from an authorized Atomic dealer (purchases from us qualify). Wear items like mouthpieces, hoses, and o-rings carry a 2-year warranty.
