Affordable High-Performance Backup Regulator

When it comes to your dive gear, “backup” doesn’t mean “second best.” The Atomic Aquatics Z2 Octo delivers the same effortless breathing performance and reliability as the Z2 primary regulator—just in a bright, high-visibility yellow housing for safety and convenience.

Perfect for divers who demand premium Atomic quality at an affordable price, the Z2 Octo is engineered with Zirconium-plated brass and Titanium components that resist corrosion 3–4 times better than standard chrome. It’s built to last and perform flawlessly, whether you’re exploring Lake Norman, the Florida Keys, or deep wreck dives off the Carolina coast.
