DIR Regulator Set – 1st Stage V2 + 2nd Stage TEC1 + Pressure Gauge

Definitive twinset mirrored configuration compliant with DIR standards. Includes two V2 ICE asymmetrical "V" diaphragm first stages, high-performance adjustable second stages, metal technical pressure gauge, and accessory kit.

The Tecline V2 ICE TEC1 Regulator Set + SPG DIR Set, available at DIR-STORE, is the high-end, all-in-one solution developed for technical divers facing the harshest environmental conditions, including deep ice and cave explorations. This premium package integrates the main and backup breathing groups with pressure control (SPG). Leveraging the "V" mirrored architecture of the V2 ICE first stages, the hoses run extremely linearly along the cylinder profile, significantly improving in-water trim and allowing the head to move freely. Certified well beyond the requirements of the strict European standard EN250A, it offers top-tier fluid dynamic and thermal performance.

Technical Features:

• Dual V2 ICE First Stage (Mirrored Asymmetrical Design for Twinset): Made of high-quality marine bronze, the V2 ICE first stages feature a balanced diaphragm mechanism with a sealed dry chamber (Dry Chamber) and Cold Kit for icy waters. Unlike traditional models, the pair is divided into a right body (2 LP / 1 HP) and a left body (2 LP / 1 HP). This ultra-clean layout is geometrically angled to ensure hoses run parallel and eliminate any forced bends. Maximum operating pressure at 300 bar.
• Dual TEC1 Second Stage (Smooth and High-Flow Breathing): The two pneumatically balanced second stages maintain minimal inspiratory effort at any depth, compensating in real-time for pressure changes within the cylinder. The classic design ensures precise delivery and extremely simple field maintenance, while the casing is reinforced by a protective anti-impact aluminum perimeter ring.
• Technical SPG 52 mm Metal Pressure Gauge: The set includes a professional diving pressure gauge with a chrome-plated brass case and 52 mm tempered glass. Equipped with a high-readability luminous dial, it is paired with a black high-pressure (HP) hose.
• Anti-Free-Flow Control and Adjustments: 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.
• Custom Hose Option (DIR Layout): The lengths of all hoses included in the set can be selected during the order placement for a perfect fit:
• LP Donor Regulator Hose: 1.93 m / 2.00 m / 2.10 m
• LP Backup Regulator Hose: 0.61 m
• HP Pressure Gauge Hose: 0.57 m / 0.60 m / 0.65 m
