Hogarthian Octopus Set – 1st Stage V1 + 2nd Stage TEC1 + Pressure Gauge

Advanced DIR / Hogarthian style technical configuration for single tank, based on the revolutionary V1 ICE first stage with 45° angled ports. This allows for a perfect and tension-free hose routing, equivalent to the V2 system for twin tanks. Includes V1 ICE first stage, two balanced TEC1 second stages (primary and backup with bungee), 1.93 m long hose, compact pressure gauge with short hose, stainless steel single-ended bolt snaps, and carrying bag. Choose your hoses directly from the dropdown menu.

The Tecline V1 TEC1 + SPG Hogarthian Octopus Set, available on DIR-STORE, is the definitive solution for single-tank divers who demand clean, hydrodynamic, and kink-free hose routing. Designed according to the principles of the DIR (Doing It Right) philosophy and the Hogarthian system, this "SemiTec" set eliminates the classic messy arrangement of recreational octopuses: the primary regulator is mounted on a 1.93 m long hose for immediate donation, while the backup second stage is kept within reach at the neck via an elastic bungee. The heart of the system is the extraordinary V1 ICE first stage, whose downward-angled ports allow hoses to run parallel to the diver's body, reducing hydrodynamic drag and improving ergonomics.

Technical Specifications:

• V1 ICE First Stage (Balanced Diaphragm, Angled Ports and Dry Chamber): Constructed from solid chrome-plated marine brass, the V1 ICE is specifically designed for single-tank use, offering optimized routing thanks to its 45° angled LP and HP ports. Equipped with a sealed dry chamber (Dry Chamber), it completely isolates internal components from the surrounding water. This design prevents ice formation and consequent regulator free-flow, making it ideal for ice diving and extremely cold water (DIN 300 bar connection).
• Dual TEC1 Second Stages (Smooth and Balanced Breathing): Both TEC1 second stages are pneumatically balanced to minimize overall work of breathing (WOB). They ensure a constant, smooth, and linear airflow regardless of depth or residual tank pressure.
• Flow Control and Adjustments: Each second stage is equipped with an external micrometric knob for adjusting the initial inspiratory effort and a lever for managing the Venturi effect (essential for preventing the backup second stage from free-flowing when stowed at the neck via the bungee).
• Hogarthian Layout and Proflex Hoses: The set reflects a pure DIR configuration. The primary regulator is connected to the 1.93 m Proflex long hose (which passes under the right arm, diagonally up the chest, and around the back of the neck for donation in an emergency), while the backup is mounted on the 0.61 m Proflex short hose at the neck. Proflex hoses offer exceptional flexibility and significantly lighter weight than traditional rubber hoses, reducing jaw fatigue.
• SPG 52 mm Technical Pressure Gauge: The kit includes a professional analog pressure gauge with a 52 mm diameter chrome-plated brass case and a highly legible dial. It comes with a 0.60 m black high-pressure (HP) hose, ideal for attaching to the left D-ring of the harness via one of the included bolt snaps, minimizing clutter.
• Included Technical Accessories: The set comes ready for use with 2 x 88 mm marine-grade stainless steel single-ended bolt snaps (for attaching the pressure gauge and primary second stage) and an elastic bungee for the backup regulator.

Custom Configuration: On DIR-STORE, you can configure the set according to your precise diving preferences. Select the type (Rubber or Proflex/Miflex) and exact measurements of all hoses directly from the dropdown menu before adding the product to your cart!
