Best Atomic Aquatics Diving Regulators in 2026

High-Flow LP Hose & Disconnect - The high-flow, low pressure disconnect is interchangeable with many other models yet smaller size and lighter in weight.

Multi-Configuration Adaptability - The first product of its kind adaptable to a wide variety of BCD hoses and sizes. Can be fitted to virtually any make or model BCD.

Ergonomic Controls - Large oversized and ergonomically-shaped buttons are easy to find for pneumatic or oral inflation/deflation.

Smaller and lighter than the S600 but using the same-sized diaphragm, the S620 Ti delivers instant air on demand with super inhalation sensitivity.

An air-balanced flow-through piston housed in a chrome-plated brass body provides constant airflow unaffected by depth, tank pressure, or breathing rate.

SCUBAPRO’S patented Extended Thermal Insulating System insulates the inner mechanism, improving cold-water resistance without compromising breathing performance.

Second stage components are made of precision machined Brass with Zirconium plating and Titanium

Patented Atomic Seat Saving Orifice (Titanium)

Patented Atomic Automatic Flow Control (AFC)

Outfit your Atomic Z3 Regulator with your own style

Color Kit comes with: (1) Front cover (1) Adjustment knob (1) Exhaust deflector

COLORS: Gray, Blue, Yellow, Red, Black, Pink, Purple or Aqua

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

SCUBAPRO’s marine-grade, chrome-plated brass body is specially designed to reduce size and weight, making the MK11/C370 an ideal travel companion.

Equipped with an air-balanced diaphragm first-stage design, the regulator delivers a constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.

Sealed internal parts within the brass body keeps water from fouling the mechanism while improving the regulator’s performance in cold water.

Kit includes: purge cover, adjustment knob, exhaust deflector and comfort mouth piece
