Product Description
 
Scubadiving.com review

"IST Sports’ new R10 adjustable and R20 nonadjustable regulators dominated breathing simulator tests in this price group. The R20 not only earned a perfect score, it was able to exceed 300 feet at the maximum breathing rate, while maintaining a work of breathing of only 1.0 joule per liter – an outstanding achievement for a budget regulator. In-water tests show the R20 to breathe dry in all positions."




R2 Balanced Diaphragm 1st stage

  • This balanced diaphragm 1st stage, with its ambient sensing technology, is able to provide steady air supply to the second stage irrespective of pressure and or depth.
  • The innate design ensures the critical parts of the 1st stage is environmentally sealed off from the out side, leaving it free of contamination or silt built up, which could lead to serious corrosion.
  • The use of small moving parts at the heart of the regulator means low friction and low maintenance so it can work harder to deliver air to where it is needed down stream.
  • Constructed from the brass and thickly nickel electro-plated to ensure strength and reliability
  • The 2 high pressure and 4 low pressure ports are strategically placed for convenience in equipment setting up.

 

 

 

  • The breathing Tube is made from a special Polymer resin, which allows the second stage to remain neutral in the water. The benefit is less jaw fatigue and a more comfortable dive.
  • The rocker arm lever is made from stainless for smooth action and controlled breathing.
  • It's reflection system, which can be viewed inside the mouthpiece, directs air towards the mouth to create a swirling Ventri for smooth natural breathing.
  • Lightweight second stage is made of a special polymer resin which reduces jaw fatigue and helps make your dive more comfortable.
  • The high flow 2nd stage hose is specially designed for this regulator.
  • Soft black silicone mouthpiece.
  • CE Certified.
  • Exhalation is controlled by an oval exhaust diaphragm which opens with radius bends to create a tighter seal. This feature also allows for easier exhalation over the round style exhaust.
  • Each R20 regulator comes with it's own certificate of individual performance
  • 4 LP Ports
  • 2 HP Ports
