Octopus Set – 1st Stage R4WW + 2nd Stage TEC2

Complete, ultralight, and top-of-the-range configuration ideal for travel and advanced recreational diving in temperate waters (>10°C). Includes an R4 TEC WW diaphragm first stage with a wet chamber, two latest-generation TEC2 second stages with DFS technology, a pressure gauge, and a carrying bag.

The Tecline R4 WW TEC2 OCTO + SPG Regulator Set, available at DIR-STORE, represents the ultimate in breathing comfort and compactness for the discerning recreational diver who travels frequently. This exclusive package combines the extraordinary lightness of the R4 TEC WW travel first stage with the elite performance of the latest generation TEC2 second stages. Specifically designed to operate in temperate waters (above 10°C), the diaphragm system with a wet chamber ensures a constant airflow, preventing regulator imbalance at maximum depths. The second stage's fluid dynamic technology ensures minimal inspiratory work for a smooth and effortless diving experience.

Technical Features:

• R4 TEC WW First Stage (Ultralight Diaphragm for Travel): Weighing only 590 grams, this regulator minimizes baggage bulk and is ideal for frequent travelers. It uses a balanced diaphragm mechanism with a main valve and a wet chamber, optimized for temperatures above 10°C. The absence of an external environmental diaphragm protects the system from the risk of thermodynamic imbalance, preventing accidental regulator interruptions at high depths. Constructed from chromed marine bronze, it supports an operating pressure of up to 300 bar and offers 4 LP ports and 2 HP ports.
• Dual TEC2 Second Stage (DFS Technology and Ultra-Comfort): The pneumatically balanced TEC2 second stages implement the innovative Direct Flow System (DFS). This special architecture optimizes the internal gas fluid dynamics, drastically reducing overall inspiratory work (WOB) at any depth and offering incredibly smooth and natural breathing.
• Mechanical Shielding and Protection: The structural polymer casing of the second stage is frontally shielded by a solid stainless steel ring to withstand strong stresses and accidental impacts. The internal metal parts benefit from a protective non-stick Teflon coating.
• Dual Adjustment and Safety: Both second stages feature a lever for manual adjustment of the Venturi effect, essential for preventing accidental free-flow of the regulator when not in use (such as on the octopus). They also include an external micrometric knob for manually calibrating the initial breathing effort, easily operable even with thick gloves.
• High Visibility Octopus and Hose Layout: To ensure maximum buddy safety, the emergency second stage (TEC2 OCTO) is equipped with a high-visibility yellow casing paired with a dedicated 0.90 m yellow hose. The primary regulator, on the other hand, features a classic 0.70 m black hose.
• Technical SPG Pressure Gauge: The kit includes a professional analog pressure gauge with a robust metal case and a high-visibility dial that facilitates quick reading of remaining bar. It comes paired with an 0.80 m black rubber high-pressure (HP) hose.
