Atomic Aquatics SS1 – Streamlined Safe Second Stage / Inflator Combo

The Most Compact, Reliable, and High-Performance Alternate Air Source We Use

At Sink or Swim Scuba, the Atomic Aquatics SS1 is our go-to alternate air source for divers who want performance, reliability, and a cleaner gear configuration. This innovative safe second / BCD inflator combo replaces both your traditional octopus and power inflator—streamlining your setup without sacrificing safety or breathing performance.

When we rig your regulator system the Sink or Swim way, we eliminate the need for four bulky hoses. By combining the SS1 with a hoseless air-integrated dive computer, your full system runs on just two hoses—one to the SS1 and one to your primary second stage. It’s simple, sleek, and ideal for both recreational and technical divers.
