BZ-2 Second Stage
Features
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.
