Hogarthian Octopus Set – 1st Stage R4WW + 2nd Stage TEC1 + Pressure Gauge

Pure technical configuration in DIR / Hogarthian style for single cylinder, ideal for travel and diving in temperate waters (>10°C). Includes the ultralight R4 WW wet chamber first stage (only 590 g), two balanced TEC1 second stages (primary and backup with bungee), 1.93 m long hose, compact pressure gauge with short hose, single-gate stainless steel snap hooks, and carrying bag. Choose your hoses directly from the dropdown menu.

The Tecline R4WW TEC1 + SPG Hogarthian Octopus Set, available on DIR-STORE, is the definitive "ready-to-dive" configuration designed according to the rigorous standards of the DIR (Doing It Right) philosophy and the Hogarthian system for advanced recreational and technical single-cylinder diving in temperate waters. This package optimizes safety and hydrodynamics by eliminating the classic short hose configuration: the primary regulator is mounted on a 1.93 m long hose for immediate donation, while the backup second stage is kept readily accessible around the neck via an elastic bungee. Based on the ultralight R4 WW (Warm Water) first stage, it offers elite breathing performance in an incredibly compact and easy-to-transport format.

Technical Features:

• R4 WW First Stage (Balanced Diaphragm and Wet Chamber): With a record-breaking weight of just 590 grams, the R4 WW is one of the lightest technical first stages on the market, perfect for traveling divers. Specifically designed for waters above 10°C, it utilizes a balanced diaphragm main valve to ensure constant flow at any depth. The wet chamber design (without an external environmental diaphragm) reduces superfluous weight and prevents anomalies in delivery at maximum depths, offering a direct and constant mechanical response. Constructed from solid chrome-plated marine bronze (DIN 300 bar connection).
• Double TEC1 Second Stage (Smooth and Balanced Breathing): Both TEC1 second stages are pneumatically balanced to minimize initial breathing effort (WOB). They provide an incredibly smooth and constant airflow even at high depths or under extreme exertion.
• Flow Control and Adjustments: The second stages feature a side lever for managing the Venturi effect (essential for preventing accidental free-flow of the backup second stage at the neck when not in use) and an external micrometric knob for manual adjustment of the initial breathing effort.
• Hogarthian Layout and Proflex Hoses: The configuration adopts the pure DIR philosophy. The primary regulator is mounted on the 1.93 m Proflex long hose (which passes under the right arm and behind the neck to be instantly donated to the buddy), while the backup regulator is mounted on the 0.61 m Proflex short hose and held at the neck by an elastic bungee. Proflex hoses offer exceptional flexibility and significantly lighter weight than traditional rubber hoses.
• SPG 52 mm Technical Pressure Gauge: The kit includes a professional analog submersible pressure gauge with a 52 mm diameter chrome-plated brass case and a high-visibility dial. It comes with a 0.60 m black rubber high-pressure (HP) hose, ideal for attaching to the left D-ring of the harness using one of the included snap hooks, reducing bulk and hydrodynamic drag.
• Included Technical Accessories: The set comes ready for use with 2 marine-grade 88 mm single-gate stainless steel snap hooks (for attaching the pressure gauge and primary second stage) and an elastic bungee for the backup regulator.

Customization: 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!
