Engineered for demanding conditions, this advanced first stage features TBP – Twin Balanced Piston technology, fully environmentally sealed to deliver reliable performance in cold water environments.

With Natural DFC on all LP ports, it ensures consistent, high gas flow at any depth, while AST (Auto Sealing Technology) keeps the first stage dry and protected from contaminants.

The 300 bar black and gray DIN connector features a hexagonal grip design for secure handling, even with gloves. Pre-oriented LP and HP ports allow for clean, streamlined hose routing, and the compact diaphragm design enhances durability without adding bulk.

Finished in a refined pearl chrome coating, this first stage combines technical precision, rugged reliability, and sleek aesthetics for serious divers.
