Features
Features
- By merging the distinctive second stage design of Atomic Aquatics in titanium with a first stage featuring a sleek black Diamond-Like Carbon (DLC) over chrome plating, the B2x achieves a remarkable balance.
- Utilizing Atomic Aquatics’ proprietary Diamond-Like Carbon process, the B2x attains unparalleled tribological properties unmatched by any other Brass regulator. This ensures supreme durability and corrosion resistance without compromising the seamless operation of the 1st stage.
- Available in Yoke Unsealed or DIN Unsealed.
- Utilizing Atomic Aquatics’ proprietary DLC process, the B2x attains unparalleled tribological properties unmatched by any other Brass regulator. This ensures supreme durability and corrosion resistance without compromising the seamless operation of the 1st stage. Our DLC coating gives 16X more protection than just the raw metal.
- The original Atomic Aquatics B2 has garnered more awards from independent tests and reviews than any other regulator on the market and with fans in virtually every corner of the dive industry world. The signature breathing performance of the T3 was first engineered into the B2 and then the B2x with virtually the same corrosion-resistance. The difference is the metals used in the first stage, which chrome-plated and then DLC coated to increase corrosion and wear protection.
- You shouldn’t have to think about breathing when you dive. The exclusive Atomic AFC helps you breathe naturally at any depth without thinking about adjusting. The Atomic AFC eliminates the manual adjustment normally needed to regulate Venturi effect as you dive deeper. No dials to turn or buttons to push. A Rapid Adjustment Knob is included for special situations like surf entry or octo use.
- Divers deeply admire many exclusive features of Atomic Aquatics second stages that make diving easier. One of the most acclaimed is the Atomic Aquatics Comfort Swivel which allows 30° rotational movement without hose binding or kinking. The B2x stainless steel Comfort Swivel with black PVD coating for great corrosion-resistance. Once you dive more comfortably with it, you’ll wonder why no one else ever thought of it.

Frequently Asked Questions
How often does a scuba regulator need servicing?
Follow the interval in your regulator's manual, since manufacturers commonly specify an annual inspection or a set number of dives and many warranties depend on it. A regulator is life-support equipment, so service belongs with a factory-trained technician rather than being attempted at home. Have it looked at sooner than scheduled if you notice increased breathing effort, free-flow, bubbles, or water in the second stage.
How do I rinse and care for a regulator after diving?
Make sure the dust cap is dry and firmly seated over the first-stage inlet before the regulator goes anywhere near water, because water inside the first stage is the leading cause of internal corrosion. Rinse in fresh water without pressing the purge button, since purging while depressurized can draw water back into the second stage. Shake out the water and hang it to dry with the hoses in wide, gentle loops rather than tight bends.
Can I fly with a scuba regulator?
Regulators travel well and are usually best carried in hand luggage where they will not be crushed or lost. A regulator holds no gas of its own, so there is nothing inherently problematic about it on an aircraft, though the airline and security screeners always have the final say. Pack it dry with the dust cap in place, in a padded regulator bag or wrapped in soft gear.
Can I use my regulator with nitrox?
Many modern regulators are supplied as suitable for nitrox mixes up to 40 percent oxygen, which is the widely used recreational industry standard, while anything above that requires dedicated oxygen-clean equipment and procedures. Confirm what your specific regulator's manual states, and follow your nitrox training and your fill station's requirements. Never assume a regulator is oxygen-service clean simply because it looks clean or is new.
What is the difference between DIN and yoke regulators?
A yoke (A-clamp) fitting clamps over the tank valve and is the most common connection across much of the recreational world, while a DIN fitting screws into the valve and is standard in much of Europe and in technical diving. DIN captures the o-ring inside the threads, which many divers consider more secure, but yoke is often what rental cylinders provide. Adapters exist in both directions, so check what is used where you dive before deciding.
What is the octopus regulator for?
The octopus is your backup second stage, carried so you can share air with a buddy who is out of gas, or breathe from it yourself if your primary fails or free-flows. It is normally on a longer, brightly colored hose so it is easy to find and hand over under stress. Secure it in the triangle between your chin and the bottom of your rib cage so it is instantly accessible and not dragging through sand or coral.
How should I store a regulator between dive trips?
Store it fully dry, out of sunlight, with the dust cap in place and the hoses in wide loops rather than tightly coiled. Avoid hanging it by the second stages for long periods, which stresses the hose fittings; laying it flat in a padded bag or hanging it by the first stage is kinder. If it has sat unused for a long stretch, have it checked before your next trip rather than assuming it is ready to dive.
