Octopus Set – 1st Stage V1 + 2nd Stage TEC1

Complete balanced diaphragm configuration with patented asymmetric design, ideal for pure single-tank configuration and extreme cold-water dives. Includes V1 ICE first stage with dry chamber, two high-performance balanced TEC1 second stages, compact pressure gauge, and carrying bag.

The Tecline V1 TEC1 OCTO + SPG Regulator Set, available at DIR-STORE, represents a geometric revolution for advanced recreational and technical divers who primarily dive with a single tank. The heart of this kit is the renowned V1 ICE first stage, featuring an exclusive asymmetric structure that allows hoses to run perfectly parallel to the tank. This architecture eliminates hose crossovers, protects the valve, and removes any tension on the diver's mouth. Certified for the most severe Arctic conditions, this set works in symbiosis with the compensated TEC1 second stages to provide a constant and effortless airflow in any environment.

Technical Features:

• V1 ICE First Stage (Asymmetric Geometry and Under-Ice Protection): Constructed from solid chrome-plated marine brass, the V1 ICE utilizes a balanced diaphragm mechanism assisted by a sealed dry chamber. Its asymmetric angled design is specifically structured to offer an ideal and ergonomic hose routing on a single tank. Certified according to the stringent European standard EN250A for cold water, it is highly recommended for extreme dives, including those under ice. It offers a clean layout with pre-oriented LP and HP ports (DIN 300 bar connection).
• Dual TEC1 Second Stage (Smooth and Balanced Breathing): TEC1 second stages are pneumatically balanced to minimize overall work of breathing (WOB). They guarantee exceptionally smooth, natural, and consistent delivery even under high air demand or at high depths, far exceeding common recreational standards.
• Flow Control and Adjustments: Both second stages feature a side lever for manual management of the Venturi effect, essential for preventing unintentional continuous free-flow when the regulator is not in use (such as on a backup second stage positioned around the neck). They also integrate an external micrometric knob to calibrate the initial breathing effort.
• High-Visibility Octopus and Optimized Hose Layout: For perfect buddy safety, the emergency second stage (TEC1 OCTO) is instantly identifiable thanks to its yellow front cover and dedicated 0.90 m hose of the same color. The primary regulator is equipped with a short black 0.63 m hose, a length meticulously designed for the V1's asymmetric routing on a single tank.
• Technical SPG 52 mm Pressure Gauge: The kit includes a professional and compact analog pressure gauge, with a robust 52 mm diameter metal casing and a highly readable dial. It comes paired with an 0.80 m heavy black rubber high-pressure (HP) hose.
