The Dive Rite O2 Deco Regulator is a compact and streamlined solution designed specifically for shallow water decompression. Assembled in a clean room with oxygen-compatible materials, it is ready for use with higher oxygen concentrations straight out of the box. Featuring an unbalanced piston DIN first stage and a balanced downstream second stage, the O2 Deco Regulator ensures consistent performance during decompression stops. The adjustable second stage allows divers to fine-tune inhalation effort for comfort. Please note, this regulator is intended solely for deco use and should not be used deeper than 50 feet (15 m) or as a stage/travel regulator.
