Set Octopus – 1st Stage R4 + 2nd Stage TEC2

Complete balanced diaphragm, compact, top-of-the-range configuration for advanced recreational diving and travel. Includes R4 TEC first stage with dry chamber, two latest-generation TEC2 second stages with DFS technology, compact 52 mm pressure gauge, and carry bag.

The Tecline R4 TEC2 OCTO + SPG Regulator Set, available at DIR-STORE, represents the perfect combination of maximum thermal protection from a compact diaphragm first stage and the elite fluid dynamic performance of the latest-generation TEC2 second stages. This premium package is the ideal choice for demanding divers who frequent cold waters or rigid thermoclines, but also desire a light and space-saving kit for their travels. Thanks to the sealed dry chamber and the direct flow system of the second stages, the set minimizes breathing effort at any depth, ensuring an exceptionally comfortable and stress-free diving experience.

Technical Features:

• R4 TEC First Stage (Balanced Diaphragm, Compact with Dry Chamber): Constructed from solid chrome-plated marine brass, the R4 TEC utilizes a balanced diaphragm mechanism characterized by a significantly lighter and more compact body compared to standard turret models. The sealed dry chamber completely isolates the internal moving components from the external environment, acting as a total anti-freeze and anti-sediment barrier. It offers a rational layout for clean hose routing thanks to 4 LP and 2 HP symmetrical outlets (DIN 300 bar connection).
• Double 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 the overall work of breathing (WOB) at any depth and offering incredibly smooth and natural breathing.
• Mechanical Shielding and Protection: The structural polymer casing of the second stage is shielded at the front by a solid stainless steel ring to resist strong stresses and accidental impacts. The internal metal parts benefit from a non-stick Teflon protective coating to maximize longevity.
• Flow Control and Adjustments: 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 (such as on the neck octopus). They also include an external micrometric knob to calibrate the initial breathing effort.
• High Visibility Octopus and Hose Layout: For perfect buddy safety, the emergency second stage (TEC2 OCTO) is instantly identifiable thanks to its yellow front cover and a dedicated 0.90 m hose of the same color. The main regulator is equipped with a classic black 0.70 m hose.
• 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 legible dial. It is supplied paired with a heavy black rubber high-pressure (HP) hose of 0.80 m.
