With its extremely wide power spectrum, the M1 is suitable for the most demanding diving conditions imaginable
This compact, ultra-rugged Stage 1 is the result of combining the time-tested DS4 platform with MTX technology. A robust dry chamber closure with a reinforced membrane helps prevent ice build-up while protecting the regulator from impact. A heat exchanger around the diaphragm increases the temperature of the breathing mixture inside the 1st stage. Classic shape is suitable for most configurations - single-bottle diving, twin-bottle diving, stage.
DB4+ has two high pressure outlets.
