DIR Regulator Set – 1st Stage V1 + 2nd Stage TEC2 + Pressure Gauge

Complete twinset configuration to DIR standards. Includes two monolithic V1 ICE diaphragm first stages with "V" arrangement, ultra-compact top-of-the-range second stages, technical metal manometer, and accessory kit.

The Tecline V1 ICE TEC2 + SPG DIR Set Regulator Set, available on DIR-STORE, is the ultimate all-in-one technical package for divers facing the most severe environmental conditions, including deep diving under ice or in obstructed environments (caves/wrecks). Developed in full compliance with the DIR (Doing It Right) philosophy, this system integrates the main and backup breathing groups with pressure control (SPG). Leveraging the asymmetrical "V" routing of the V1 ICE first stages, the hoses run extremely linearly and hydrodynamically along the BCD bag profile, drastically reducing bulk behind the head and eliminating mechanical wear points. Certified according to the rigorous parameters of the European standard EN250A, it offers top-tier fluid dynamic performance.

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 dry sealed chamber and an integrated Cold Kit. This total insulation protects springs and internal components from freezing and sediment. The fixed angled "V" layout naturally orients the hoses and prevents annoying crossovers at neck height. Each first stage offers 4 LP and 2 HP ports.
• Dual TEC2 Second Stage (DFS Technology and Ultra-Comfort): The pneumatically balanced second stages implement the innovative DFS (Direct Flow System) direct flow system. This architecture optimizes the internal fluid dynamics of the gas, minimizing overall inspiratory work (WOB) at any depth, regardless of residual cylinder pressure.
• Anti-Freeze and Mechanical Shielding: The structural polymer shell is frontally shielded by a solid stainless steel ring to withstand strong stresses and impacts in caves. Internal metal parts benefit from a dedicated heat exchanger at the connection point and a protective non-stick Teflon coating.
• Technical Metal SPG 52 mm Manometer: The set includes a professional diving manometer with a chrome-plated brass case and 52 mm diameter tempered glass. Equipped with a high-visibility luminescent background, it is coupled with a black high-pressure (HP) hose with customizable length (0.57 m, 0.60 m or 0.65 m).
• Dual Adjustment and Safety: Both second stages feature a lever for Venturi management (essential for inhibiting accidental continuous flows on the second stage positioned at the neck) and a micrometric knob for manually calibrating inspiratory effort.
• Custom-Made DIR Style Hose Geometry: The included hoses faithfully follow the technical standard: a long hose (long hose) of 1.93 m, 2.00 m, or 2.10 m for the primary second stage (the donor), a short hose of 0.61 m for the neck backup, and a dedicated HP hose for the manometer.
