We understood that not every diver could afford Titanium.
Even though every Atomic regulator has all metal second

M1 Monel & Brass First Stage
Nitrox Ready to 80%
Performance in extreme conditions requires extreme
engineering. The Atomic M1 first stage utilizes Monel and
Brass for factory-ready Nitrox mixtures to 50% or Oxygen
mixes up to 80% when special guidelines are followed. The
selection of Monel, which is widely used in marine applications,
further demonstrates how adeptly Atomic chooses a material
to perform a specific fuction required by divers.
