Divers on a budget can experience virtually the same easy, natural breathing and corrosion-resistance as the entire Atomic regulator line. The performance is delivered from patented Atomic exclusives including the Jet Seat piston and AFC. The economy is achieved from exclusive use of Zirconium-plated Brass materials.

Shortly upon launch, the Atomic Z2 quickly developed a reputation as a superb breather. When subjected to ScubaLab’s standard simulator test protocols, the Z2 delivered perfect simulator scores. When pressed to the limit, it was able to achieve one of the best breathing rates of this group, just over 87 RMV. This superior performance carries into the water as well, where test divers found the reg a very easy and dry breather in all positions with an excellent purge. The Z2 has a new high-flow second stage casing similar to what’s on the new T2. Like all Atomic regs, the Z2 also uses Atomic’s patented Automatic Flow Control and comes with a great dual composite mouthpiece.

Pair the Z2 first and second stage with a matching Z2 Octo for an amazingly affordable regulator set.
