    outperform and outlive traditional rubber hoses

  • Pneumatically balanced second stage 
  • Environmentally sealed first stage provides greater reliability, less maintenance and higher performance  
  • "Diver Adjustable" Air flow
  • Nitrox Compatible to 40% (The Recreational Limits of Nitrox)
  • Lightweight 2nd stage to prevent jaw fatigue and add to overall comfort
  • Easy grip controls even while wearing gloves
  • "Diver Adjustable" venturi to prevent unwanted free-flow

Reviewer: David Herzog  -  View all my reviews
this is by far the best regulator ive ever used. it is completely even though all depths and super-easy to adjust (although theres usually no need to make any adjustments it works great on all settings). just dont forget to flip the travel swich before use! i feel safer using this. anything by hollis is tops.
