Product Description



The R-400 First stage features a balanced diaphragm system and upgraded HP poppet assembly for enhanced reliability in 2008-09. This balanced diaphragm system maintains minimum variation in intermediate pressure in relation to changes in residual tank pressure. The ports feature two high flow low-pressure ports to optimize second stage performance for easier breathing.

The S-60 second stage features a diver adjustable sensitivity control to deliver air smoothly with each breath. The exhaust valve features a large and flexible design for extremely low exhaust resistance.

Regulator Options:

  • TUSA RS-460 II INT (A-Clamp) Regulator, or:
  • TUSA RS-460 II DIN Regulator.

Detailed Features:

1st Stage - Balanced Diaphragm Type First Stage (R-400):
Upgraded with a new poppet assembly for 2008-09, the balanced diaphragm system features a minimum variation in intermediate pressure in the relation to changes in residual tank pressure. The diaphragm first stage also offers excellent performance in all water conditions due to its sealed design.

1st Stage - High Flow Low Pressure Ports:
Two high flow ports are engineered for the smoothest air delivery possible to the primary second stage and octopus at all tank pressures.

1st Stage - Cold Water Insulation System:
The R-400 first stage features a special coating on the main spring to ensure that the regulator performs in all diving conditions.

1st Stage - Available in Yoke or 300 bar DIN:
The regulator first stage can be converted from a yoke connection to a 300 bar DIN connection.

2nd Stage - Adjustable Surface or Diving Sensitivity Control:
The "Surface" or "Dive" control allows the user to set the ease of breathing for varying sections of the dive. The surface position decreases the likelihood of a free flow and also is recommended for cold water diving. In the dive position the control allows the regulator to power assist the diver as they breathe using the venture effect.

2nd Stage - Ortho-Consciously Designed Mouthpiece
The new mouthpiece, developed on the basis of ergonomic engineering, further enhances the comfort of bite, fit, and stability. Even with a light bite, a high level of stability is achieved, so there is no fatigue from long periods of usage.
