DIR Regulator Set – 1st Stage V1 + 2nd Stage TEC1 + Pressure Gauge

Complete twinset configuration to DIR standard. Includes two monolithic V1 ICE diaphragm first stages with a "V" arrangement, adjustable second stages, a technical metal pressure gauge, and an accessory kit.

The Tecline V1 ICE TEC1 + SPG DIR Set Regulator Set, available on DIR-STORE, is the high-end, all-in-one solution designed for technical divers who face the most severe conditions, including ice diving and diving in confined environments (caves/wrecks). Developed in full compliance with the DIR (Doing It Right) philosophy, this package integrates the primary and backup breathing apparatus with the pressure control system (SPG). Leveraging the "V" geometry of the V1 ICE first stages, the hoses are routed in an extremely hydrodynamic way, eliminating hose crossovers behind the head and ensuring maximum freedom of movement. Certified according to the stringent parameters of the European standard EN250A, it offers impeccable delivery at any depth.

Technical Features:

• Dual V1 ICE First Stage ("V" Geometry and Arctic Protection): Constructed from high-quality chrome-plated marine bronze, the V1 ICE first stages feature a balanced diaphragm mechanism assisted by a sealed dry chamber (Dry Chamber) and an integrated Cold Kit. This total insulation protects the internal springs and mechanisms from freezing and sediment. The "V" oriented port layout allows hoses to run linearly and cleanly along the profile of the BCD bladder, drastically reducing the risk of entanglement. Each first stage offers 4 LP and 2 HP ports.
• Dual TEC1 Second Stage (Smooth Delivery and High-Flow): The two pneumatically balanced second stages instantly compensate for pressure variations within the tank, minimizing inhalation effort at any depth. The shock-resistant technopolymer casing is reinforced by a protective aluminum perimeter ring, and the classic design ensures extremely simple field maintenance.
• 52 mm Metal Technical SPG: The set includes a professional diving pressure gauge with a chrome-plated brass case and 52 mm diameter tempered glass. Featuring a high-visibility luminous dial, it is paired with a black high-pressure (HP) hose of customizable length (0.57 m, 0.60 m, or 0.65 m).
• Anti-Free-Flow Control and Safety: Both second stages integrate a lever for manual adjustment of the Venturi effect (essential to prevent accidental free-flow of the backup second stage positioned at the neck) and a micrometric knob to calibrate breathing effort. A metallic heat exchanger on the hose counteracts ice formation.
• Custom DIR Style Hose Geometry: The included hoses faithfully follow the technical standard: a long hose (1.93 m, 2.00 m, or 2.10 m) for the primary second stage (the donor), a short hose (0.61 m) for the neck backup, and a dedicated HP hose for the pressure gauge.
