Hogarthian Octopus Set – 1st Stage R5 + 2nd Stage TEC2 + Pressure Gauge

Advanced DIR / Hogarthian style technical configuration for single tank, based on the compact R5 balanced diaphragm first stage and the latest generation TEC2 second stages. Includes R5 first stage, two TEC2 second stages with DFS technology (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 R5 TEC2 + SPG Hogarthian Octopus Set, available on DIR-STORE, combines the extraordinary compactness and robustness of a dry chamber first stage with the maximum delivery performance of the latest generation TEC2 second stages. Designed faithfully following the principles of the DIR (Doing It Right) philosophy and the Hogarthian system for single tanks, this kit eliminates the bulk and rigidity of traditional systems: 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 a comfortable elastic bungee. An excellent choice for divers who desire a constant airflow and unbeatable breathing comfort in any thermal conditions.

Technical Features:

• R5 First Stage (Balanced Diaphragm and Dry Chamber): Made of solid chrome-plated marine brass, the R5 is an exceptionally compact diaphragm first stage. The presence of the sealed dry chamber hermetically isolates all internal mechanical components from the external environment. This design eliminates the risk of freezing (free-flow) in cold or deep water and prevents the ingress of sand, mud, or sediment (DIN 300 bar connection).
• Dual TEC2 Second Stage (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-flows 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 neck 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 than traditional rubber hoses.
• Technical SPG 52 mm Pressure Gauge: The kit includes a professional analog underwater pressure gauge with a 52 mm diameter chrome-plated brass casing and a highly legible dial. It comes with a 0.60 m black rubber high-pressure (HP) hose, ideal for attachment to the left D-ring of the harness via one of the included snap hooks, reducing bulk and hydrodynamic drag.
• Included Technical Accessories: The set comes ready to use with 2 single-gate 88 mm stainless steel marine-grade 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!
