Please see attached for more photos and information. The condition is used, and it is the Z3. It was used for 6 months in our rental line with approximately 40-50 dives on it. It was cleaned, sanitized, then put in storage as I was moving warehouses. I disconnect most of the hoses for storage to ensure to ensure no cuts or tears. There's a new swivel hose attached to one of the second stages that is brand new ($100 hose included).

As with any used regulator, I would recommend having it serviced even though I am an Atomic service tech, and most major brands. 

The Atomic Aquatics Z3 Regulator Set is a high-performance scuba system built on a Zirconium-plated brass platform. These specific units were used gently in our rental line and have been sanitized and stored properly since closing our retail store. The balanced Jet Seat high-flow piston first stage features 2 high-pressure and 7 low-pressure ports, offering flexible hose routing and Nitrox compatibility up to 40% O2.

The second stage features a 30-degree comfort swivel hose to eliminate jaw fatigue and depth-activated Automatic Flow Control (AFC) for seamless breathing. Its patented titanium seat-saving orifice protects the internal seals during storage, which helps maintain its generous 2-year or 300-dive service interval.
