This package pairs the Atomic TFX Regulator Sealed Black with the Atomic Aquatics B2 Octopus for a complete first stage, second stage, and alternate air source setup from one maker. The TFX first stage is environmentally sealed for saltwater use, and its side-exhaust design is built to reduce breathing resistance compared to rear-exhaust regulators, so you get a smooth, natural breathing experience in any diving position. The sealed black finish is corrosion resistant, which matters for long-term reliability in a saltwater gear setup. Choose the connection that matches your tank valve: this bundle is available in YOKE or DIN.
The B2 Octopus rounds out the setup as your safe second stage for air sharing in an out-of-air situation. It’s built with all-Titanium second stage components for corrosion protection and lightweight durability, and it comes with a 36-inch hose for flexible positioning and easy access when you need to hand it off. A Comfort Swivel keeps operation smooth underwater, and the bright yellow housing makes the octopus easy for a dive buddy to spot quickly.
Together, the TFX Sealed Black regulator and the B2 Octopus give you a matched Atomic Aquatics breathing system, first stage through backup second stage, ready to configure for your tank and go.
