  • Pneumatically Balanced Second Stage for solid performance and reliability
  • Ergonomic one handed diver-adjustable inhalation effort knob and Venturi Inhalation Assist (VIA) lever, making perfect regulator tuning a breeze
  • Small size housing with a full faced soft flexible purge button makes it the right choice for all environments including sandy beaches. No “STUCK” purge buttons anymore.
  • All chromed metal components – inlet tube, orifice, inhalation control knob and cooling connector and nut – for excellent performance even in cold water.
  • Metal components also allow for extremely easy breathing while also retaining heat and moisture from exhaled breath. This provides increased resistance to freezing in cold water and less “dry mouth”.
  • Expanded exhalation port and diffusing T piece, both reducing CO2 buildup while pushing the exhaltion bubbles further away from the front of your face. No more bubbles in your face.
