About Hollis DC7 500SE Regulator with Maxflex Hose

The Hollis Gear DC7, 500SE Regulator incorporates a High Performance Over-Balanced Diaphragm First Stage that provides Progressively Greater Intermediate Pressure as Depth and Gas Density Increases for Superior Gas Delivery under the Most-Extreme Conditions. This Regulator System is designed to withstand the Rigorous CE Standard for Coldwater Performance. The Balanced Diaphragm, First Stage Regulator is inherently Environmentally Sealed. The benefit of this type of First Stage design is that none of the Delicate Internal Parts are Exposed-to-Contaminants such as Salt, Sand, Chlorine or Pool Acids. These Environmental Contaminants can cause Corrosion and Mineral Deposits to form on the Internal Mechanism Deteriorating Regulator Performance. A Diaphragm First Stage Regulator requires Less-Maintenance then Regulators that allow the Contaminates to enter the Internal Mechanism.

In addition the DC7 First Stage Regulator has a Secondary Diaphragm to completely Seal-Off the Main Spring Cavity. A Sealed Balanced Diaphragm design; Isolate the Main Spring Cavities Internal Components from the Environment. It also means the DC7 is excellent for Ice Diving (it won't freeze up) or Diving in Waters Filled-with-Contaminants or Sediment (it won't corrode). This DIN 300 bar (4350psi) First Stage Regulator is manufactured from Marine Grade Brass with a Black Anodized Finish and has 4-Low Pressure (LP) 3/8" Threaded Fixed Ports and 2-High Pressure (HP) 7/16" Threaded Ports. The Fixed Hose Routing is Ideal for both Back Mount and Side-Mount Configuration. The Regulator is NITROX Compatible to 40% Out-of-the-Box.

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 DELRIN Plastics, Rubber, Stainless Steel and Chrome Plated Brass with Silicone Rubber Components. The Hollis Gear DC7, 500SE Regulator comes standard with a 30" (76cm) MAXFLEX Hose. The MAXFLEX Hose is a Lightweight, Flexible, Braided Hose designed to Outperform and Outlive Traditional Rubber Hoses. The Hoses Flexibility further Reduces-Jaw Fatigue. The Regulator also comes equipped with a Bolt Snap Tie Point; Owner's Manual and is covered by a 24 month limited warranty.

The Hollis DC7 500SE Regulator with Maxflex Hose is commonly used for Extreme Depths and more. The Hollis DC7 500SE Regulator with Maxflex Hose is popular because customers like the following qualities of the Hollis DC7 500SE Regulator with Maxflex Hose: Effortless breathing, Nitrox Compatible.

This beat into the dirt my ScubaPro!

Brother, if you want the finest breathing regulator on the planet - this IS it! This ain't you uncle Joe's Cobra or Possiden, this is everything they wanted to be and so much more. When breathing it seems there is about a .0000000001 delay while the regulator is thinking, "What does this guy need RIGHT NOW?" and it gives it to you! It is DIN but is Yoke adaptable and beautiful in it's looks and theory. Some have tired it and said, it free-flows too eaisly but that's only if you don't unders...

Better than my Omega 2? NOPE

Took delivery before my August dive trip to Cozumel. Whistled underwater, breathed not so well, NO freeflow, difficult to purge. Found out it is NOT field serviceable. LP said send it back on my return. Took to local Oceanic dealer who said a spring was missing and charged me $10 to adjust, certainly easier than a return to LP. Breathes very well now, very dry, but it is heavier than my Omega 2. Kind of a hassle, though--missing spring? The one up next to the purge? NOT cool.

Lightweight and Breathable

By

from Sunapee, NH, US

What a fantastic regulator. It is extremely light and breaths superbly. I was hesitant to replace my longstanding Poseidon Jetstream and Cyclone regulators with the DC7 500SE as these workhorses are known for their superb breathing rates at any depth. This reg is much better than the Poseidons. It is lighter an breathes easier. The side exhaust is perfect for bailout or sidemount. Highly recommend purchasing a couple of these.

Easy breather and great bottom time

By

from Hoboken, NJ, US

I have used my new regulator for 6 dives so far. Easy breather and I had much better bottom time than before. It allows me to easily breath the right amount of air. The side exhaust kept the bubbles out of my face. I do a lot of photography and it is a definite plus. I read about complaints of free flowing. I had not had any free flow problems. Those with it were not using the regulator properly.

Heavy but very functional

By

This is a great reg and it's very durable, it is however rather heavy so make sure your mouth piece fits you really well. The side vent is especially handy for photography but can be a tad annoying if you are putting the vent directly under your head while exhaling. The purge button is also not in the traditional location (eg on the front). It's the grill next to the exhaust piece. If you can get used to that new location everything should be fine.

hollis 500se

By

old school, new tech really does say it all! This is the same basic platform as the tried and true original oceanic omega regulator, but beefed up and infused with new technology, not even a hint of a wet breather anymore. very few moving parts means its almost fail proof. after 20 years I still dive with my oceanic omega 1 as a back up to my new 500se, if that says anything about their quality! it truly is an effortless breather at any depth and any angle of diver position! if you sip air, it will sip air with you and if you are working against a heavy current it can deliver as much air as fast as you can breathe it!

Questions & Answers Powered by TurnTo®

Questions about this item:

Karen Y  I just received this today. The owners manual enclosed does not cover the 500SE 2nd stage. Is there an owners manual available for this one specifically?
barb p  Mine didn't come with one as well. . But if you Google search hollis 500se owners manual the pdf file from hollis is the top results... Hope this helped
TODD M  All owners manuals are available on Hollis's website, it is a fairly straightforward regulator, should be no need to adjust it out of the box just hook it up to your tank and breathe easy. The adjustment screw is in the middle of the diaphragm purge, but again should need no adjustment.
KEVIN F  The most current Regulator Owner's Guide can be found here: http://www.hollis.com/media/wysiwyg/HO/manuals/HO_manual_reg_12-4014-r07.pdf
Sebastien P  hollis DC7 or oceanic omega?
Joe S  The Oceanic FDXi and Hollis DC7 1st Stages are the same in performance. The difference is the Oceanic has a rubber boot around the body. The 500SE performs slightly better than the Omega 3 and is a little lighter weight.
Shopper  how many Hp ports on 1st stage?
TOM H  It has only 2
TODD M  2
Frank L  As stated in the description, this reg has 2 high pressure ports.
