The DR second stage has a full metal body. It is compact and robust in high-strength nickel-plated and chrome-plated brass.
The high-performance second stage uses the V.A.D. system, which offers constant airflow at any depth.
The special 'Mesh Grid' design of the cover prevents free-flow in the presence of strong currents.
The LP hose is made of rubber to ensure greater resistance to cuts, abrasions, bursting, UV rays and for less floating.
The main features of the DR second stage are:
• High performance second stage
• VAD system – Stable airflow without excessive positive breathing pressure
