Hogarthian Octopus Set – 1st Stage R4WW + 2nd Stage TEC2 + Pressure Gauge

Advanced DIR / Hogarthian style technical configuration 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 latest generation TEC2 second stages with DFS technology, 1.93 m long hose, compact pressure gauge with short hose, single-gate stainless steel carabiners, and carrying bag. Choose your hoses directly from the drop-down menu.

The Tecline R4WW TEC2 + SPG Hogarthian Octopus Set, available on DIR-STORE, is the ultimate combination for advanced recreational and technical divers who want to adopt the rigorous Hogarthian (DIR) system geometry during their travels or in temperate waters, while taking advantage of the superior performance of the very latest generation second stages. 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 at the neck via an elastic bungee. Based on the ultralight R4 WW (Warm Water) first stage, it offers maximum breathing performance in an incredibly compact and lightweight format.

Technical Features:

• R4 WW First Stage (Balanced Diaphragm and Wet Chamber): Weighing a record-breaking 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 external environmental diaphragm) reduces unnecessary 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).
• Dual TEC2 Second Stages (DFS Technology and Elite Ergonomics): The latest generation TEC2 second stages integrate the innovative DFS (Direct Flow System) direct flow architecture. This design optimizes internal airflow to minimize breathing effort (WOB) at any depth. The cover is shielded by a solid anti-shock stainless steel ring, and the internal metal parts are protected by an anti-friction Teflon coating.
• Flow Control and Adjustments: Both second stages are pneumatically balanced and feature a side knob for micrometric adjustment of the initial inspiratory effort, as well as a lever for managing the Venturi effect, essential for preventing free-flow when the backup second stage is positioned at the neck via the bungee.
• Hogarthian Layout and Proflex Hoses: The configuration adopts a 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 nape for instant donation to a buddy), while the backup regulator is mounted on the 0.61 m Proflex short hose and held at the neck via the elastic bungee. Proflex hoses offer exceptional flexibility and significantly lighter weight compared to traditional rubber hoses.
• SPG 52 mm Technical Pressure Gauge: The kit includes a professional analog underwater 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 with one of the included carabiners, reducing bulk and hydrodynamic drag.
• Included Technical Accessories: The set comes ready to use with 2 x 88 mm marine-grade stainless steel single-gate carabiners (for attaching the pressure gauge and primary second stage) and an elastic bungee for the backup regulator.

Customization: At 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 drop-down menu before adding the product to your cart!
