Octopus Set – 1st Stage R4WW + 2nd Stage TEC1

Complete, compact, and high-performance configuration, ideal for travel and advanced recreational diving in temperate waters (>10°C). Includes R4 TEC WW diaphragm first stage with dry chamber, two high-performance balanced TEC1 second stages, enlarged 63 mm pressure gauge, and carrying bag.

The Tecline R4 WW TEC1 OCTO + SPG Regulator Set, available on DIR-STORE, combines the extraordinary lightness and compactness of the R4 TEC WW travel first stage with the superior and smooth delivery of the balanced TEC1 series second stages. Designed for advanced recreational divers seeking a high-performance yet easy-to-transport kit, this system is specifically engineered to operate in temperate waters with temperatures above 10°C. The diaphragm mechanism with a dry chamber ensures a constant airflow, preventing regulator imbalance at maximum depths. The inclusion of an enlarged 63 mm pressure gauge ensures immediate residual pressure readings in any visibility conditions.

Technical Features:

• R4 TEC WW First Stage (Ultralight Diaphragm for Travel): Weighing only 590 grams, this reducer minimizes bulk in luggage and is ideal for frequent travelers. It uses a diaphragm mechanism with a balanced main valve and a dry chamber, optimized for temperatures above 10°C. The absence of an external environmental diaphragm protects the system from the risk of thermodynamic imbalance, preventing interruptions in delivery at high depths. Constructed from chrome-plated marine bronze, it supports an operating pressure of up to 300 bar and offers 4 LP ports and 2 HP ports.
• Dual TEC1 Second Stage (Soft Breathing and High-Flow): Unlike standard recreational models, TEC1 second stages are pneumatically balanced to minimize overall inspiratory effort. They provide natural, soft, and perfectly stable breathing even under high air demand. The casing is designed to withstand intensive use and strong mechanical stress.
• Flow Control and Thermal Safety: Both second stages feature a lever for manual adjustment of the Venturi effect, essential to prevent accidental free-flow of the regulator when not in use or during entry into the water. They also include an external micrometric knob for manually calibrating the sensitivity of the initial breathing effort.
• High-Visibility Octopus and Hose Layout: To ensure maximum buddy safety, the emergency second stage (TEC1 OCTO) is equipped with a high-visibility yellow cover paired with a dedicated 0.90 m yellow hose. The main regulator features a classic 0.70 m black hose.
• Enlarged SPG 63 mm Pressure Gauge: The kit includes a professional analog pressure gauge with a robust metal casing and a generous 63 mm diameter dial, which greatly facilitates quick reading of residual bar pressure. It is supplied paired with a 0.80 m black rubber high-pressure (HP) hose.
