Product Description

TUSA RS-790-02 and SS-0001 Regulator Package

The TUSA RS‑790‑02 / SS‑0001 Regulator Package delivers dependable performance, smooth breathing, and essential simplicity for divers who want a trusted air delivery system without unnecessary extras. At its core is the RS‑790‑02 regulator, a balanced diaphragm design engineered to perform in a wide range of conditions, including cooler water, making it a versatile choice for recreational and frequent divers alike.

Paired with the reliable SS‑0001 safe‑second octopus, this package provides a complete primary and alternate air source setup with smooth inhalation and adjustable Venturi control for customized airflow underwater. Both the regulator and octopus feature ergonomic mouthpieces designed to reduce jaw fatigue during longer dives.

Instead of bulky extras, this package includes a TUSA tote bag, ideal for easy transport or storage of your regulator gear between dives or when traveling to new dive destinations. With solid build quality and balanced performance, this regulator package is perfect for divers building out their gear or upgrading to a reliable, performance‑focused breathing system.

Key Features:

  • RS‑790‑02 Balanced Diaphragm Regulator – Delivers stable, smooth airflow in a range of diving conditions, including colder water environments.
  • SS‑0001 Safe‑Second Octopus – Pneumatically balanced alternate air source with Venturi adjustment for easy breathing and controlled airflow.
  • Ergonomic Mouthpieces – Designed for comfort and reduced jaw fatigue on extended dives.
  • Balanced Performance Package – Includes essential components without unnecessary extras, focused on core breathing performance.
  • TUSA Tote Bag Included – Convenient carrying solution for transport and storage.

R-700 First Stage


Dry Ambient Pressure Chamber
The dry ambient pressure chamber on the R-700 prevents water contact with the diaphragm and spring maximizing performance, at any depth, in cold water conditions below 50°F/10°C.

Ideal For Cold Water Environments
The R-700 is engineered for cold water diving. It features a ribbed top cap section that acts like a radiator to increase the surface area for heat transfer. This design allows warming of the critical internal first stage parts that can freeze due to the gas pressure drops and low temperatures.

High Flow Ports

Two high flow low pressure ports are available on the R-700 in addition to two standard LP ports and 2 HP ports. The high flow ports are positioned near the diaphragm and offer up to a 15% increase in air flow.

S-90 Second Stage


Pneumatically Balanced System
The S-90 second stage is a pneumatically balanced design. A small chamber positioned at the end of the poppet assembly traps air and forces the poppet back against the intermediate pressure orifice. This provides decreased inhalation resistance and increases smooth breathing in all conditions.

Venturi Adjustment Lever
The S-90 is equipped with a built-in Venturi adjustment lever. Two positions are selectable by the diver. Use Surface or the minimum setting when entering the water or on the surface, reducing the sensitivity and possible free flow of the second stage. Use the Dive or maximum setting for maximum air flow during the dive.
