About Hollis 500SE Second Stage Only With-Out Hose

Old School, New Tech, the new 500SE Utilizes a Servo Controlled Valve to provide Precision Airflow and Unparalleled Performance for both AIR-and-TRIMIX Divers in a Side-Exhaust Configuration. To achieve this, Hollis Gear has perfected the Original "Lever-Servo Valve" they designed 35 years ago. The smallest, gentlest inhale starts the servo valve working as air starts to flow into the second stage it creates a vacuum behind the diaphragm, drawing it inwards and quickly opening the valve further. Air flow is increased by allowing it to flow through multiple valve ports rather than a single port.

This Pneumatically Balanced Regulator has a Large Soft-Purge Cover or Easy Clearing of the Regulator, Patented Orthodontic Mouthpiece for Comfort and Reduced Jaw Fatigue. Regulator is Easy to Disassemble without the use of Tools and even Underwater if necessary. Regulator can be configured for Left-or-Right Positioning, no Upside Down. The obvious feature of the Side Exhaust Configuration is that Bubbles don't get in a Diver's Face when they Exhale. Recreational Divers and especially Underwater Photographers will appreciate that. Regulator is made from Impact Resistant Plastics, Stainless Steel and Chrome Plated Brass with Silicone Rubber Components. Regulator is covered by a 24 month limited warranty.

Happy, happy, happy

from Scotia, NY, US

Background: I've been diving a Cressi XS2 and was happy with the way it breathed. I bought the Hollis 500SE for the side exhaust. When I first dove the 500SE it was a totally different experience. No bubbles - none - they all went to the side out of sight. But the most amazing thing was how SMOOTH the 500SE breathes. It's like there is no cracking pressure. You start to breathe in and air flows immediately. WOW - I now see what I was missing. Also with the exhaust extending to the side it is completely balanced in my mouth - no tugging to the side because of hose weight - and the mouthpiece is wonderful. I actually forgot the reg was in my mouth. It was like breathing at the surface. I can't imagine using any other reg after using the Hollis 500SE. I'm spoiled.

Questions about this item:

Shopper  Why Did You Choose This?
LARRY L  Wanted the side exhaust. It's an awsome reg.
MICHAEL C  Can I use this regulator with a cressi first stage and a normal low pressure hose?
Joe S  You can use this second stage with any first stage. However, just like with any regulator, a factory specification is set on these and you have to be sure that the Intermediate Pressure is set properly on the other first stage. You can have a service technician do this work for you. We always recommend that on any regulator you use the paired kits. In this case it is the DC7 Inline first stage.
