The DGX Gears D6 regulator includes an environmentally sealed, balanced diaphragm first stage together with a balanced and adjustable second stage that offers excellent quality, performance and value. This regulator package is assembled by Dive Gear Express using DGX Gears D6 first and second stages, together with our flex or rubber hose in your choice of length and also includes a free DIN regulator cap.

The DGX Gears D6 first stage is a balanced diaphragm design featuring five standard size low pressure 3/8-inch ports on a swiveling turret, and two standard size high pressure 7/16-inch ports. The first stage features a symmetric design and port alignments that support a huge variety of mounting orientations and hose routings. The fifth port on top of the turret offers an additional hose routing option that is popular for backmount manifolded double cylinder or Sidemount configurations and is a good choice as both primary and backup first stage. Environmentally sealed for cold water performance, the DGX comes standard with a 300-BAR DIN connector and is Nitrox Ready.

The DGX Gears D6 second stage is pneumatically balanced for excellent breathing at depth. Internally it contains a chrome plated brass air barrel for performance and durability. The black soft touch silicone front cover for easy purge and along with a user adjustable breathing resistance knob. It also offers the venturi (Dive/Pre-Dive) switch for better flow control when needed and to reduce free flow upon initial entry. The DGX Gears D6 second stage also includes our very popular C-Bite+ orthodontic mouthpiece (similar to the Comfo-bite™) to reduce jaw fatigue, and the SeaCure #2 mouthpiece will also work.

Any competent service tech will have no issues with service of the DGX Gears regulator models. Our suggested service interval for all DGX Gears regulators is every two years or one hundred dives. There is nothing unique about DGX Gears regulators in terms of service requirements and needs no special equipment beyond that found on the typical regulator technician bench. We believe our customers also have the right-to-repair, so we publish detailed service manuals and we sell without restriction all service parts and periodic service kits for the DGX Gears brand regulators. See the Product Attachments tab of the periodic service kits for service manuals including IPB and torque values.

Not sure what issues the guy below (above?) Had with his regulator but I had a completely different experience. Out of the box I was extremely pleased with my reg, it was assembled and tuned properly from the get go. The snap was junk, but to be expected. I've been using this regulator as a deco reg for over a year now with no problems. Would highly recommend to anybody looking for a budget but quality option for a deco/stage reg.

Some minor flaws make it undesirable
Sep 2, 2019
I waited to use this regulator many times before leaving a review. WIth about 15 dives on it now, I can say for sure it is a solid regulator at a very reasonable price. I like the cap that comes with it, which is more secure than a normal rubber cap that often comes with first stages. There are a few things I think could be better though. First, when your hoses are connected you cannot fully swivel the top and bottom sections of the first stage regulator. Not a huge deal but it's nice to be able to do that. The bigger issue is that we always seem to have to make this regulator REALLY tight on the tank, otherwise it will not seal correctly and air will spurt out. On all other regulators I have ever used, light hand-tightening is sufficient to create a seal, but this one requires very very strong hand-tightening to seal, which is a bit of a pain. Also, when you open the tank valve it lets out a his of air briefly (for about a second) before making the seal, which is concerning. Another diver mentioned that this is fairly common, but on all the other regulators I've seen or heard used on dive boats I've never seen this behavior. Also, when we are done with the dive and have to remove the first stage from the tank, it is very difficult. We have to bring some slip-joint pliers with us whenever we dive now because often we cannot get the regulator off by hand. And lastly, the o-ring on the inside of this regulator seems to always fall out, probably related to the above issues. It was probably lost 4-5 times over 3 days of diving. I think the brief "hiss" of air that happens when sealing loosens the o-ring, and the crew changing the tanks don't know this and they lose it. Every time we change our own tanks now we make sure to look and, lo and behold, it's always about to fall off when we take the first stage off the tank. Otherwise this first stage seems to perform well; but because of the flaws we probably would recommend looking elsewhere for a first stage.

I have two of these regs and I've been using them for a few years now. I have the same issue on one of them, but not at all on the other. I thought maybe that after I did the first stage service it would be corrected, but no luck. Not sure why it does this, but I can't stop it from initially leaking when pressurized. I've been using it for almost two years I think now, and that's a constant issue when doing valve drills or initially turning it on. Open - leak, close - stop leak, open - no leak. Every time. No matter how tight it is on the valve. Great otherwise..

What is the knob and lever on my second stage?

The knob and lever are used to alter the breathing characteristics of some types of regulator second stages. All our downstream design high performance second stages, including the DGX Xtra and D6, Dive Rite XT2 & XT4, MaresXR HR, and the Apeks XTX200 & XTX50 include a knob to adjust inhalation cracking pressure (aka opening effort.) Some second stages, including the DGX Xtra and D6 along with the Dive Rite XT2 & XT4 and all the Apeks XTX Series, offer a lever to disable/enable venturi assisted inhalation. The Mares XR HR/VR/SXS stages use a unique Vortex Assisted Design (VAD) system that does not require a venturi lever. Upstream designs with a servo-assist valve, such as the Poseidon Xtreme, don't normally incorporate these features because the design inherently obviates most of the need for them. Many special application designs that are light duty, such as backup (aka 'octo', 'safe second', 'alternate', 'oxygen') and BCD integrated second stages, may omit the diver adjustable cracking pressure and/or the venturi assist features for the sake of simplicity.

The knob is for diver adjustment of the cracking pressure (aka opening effort) which is the inhalation force it takes to trigger the second stage valve to open and begin to flow breathing gas to the diver. Some people might refer to this as the 'breathing resistance' but this is a misnomer because once the gas starts flowing, adjusting the cracking pressure during inhalation will have minimal effect. On most high performance designs turning the knob all the way out (counter clockwise) will cause a slight hiss or dribble of free flowing gas and turning it all the way in (clockwise) will make it difficult to breathe from the regulator. Start by setting the knob in the middle of the adjustment range and then turn the knob to set the cracking pressure to your personal preference. Some divers will occasionally adjust it during the dive based on changes in their physical effort and depth, but most divers find a setting they like and never feel a need to change it. †

Many high performance second stage designs include a venturi assist feature that reduces breathing resistance by automatically increasing gas flow during inhalation. Regulators with the venturi assist enabled are prone to free flow if the second stage is not in the mouth. The venturi lever set in the pre-dive position (-) will substantially eliminate the tendency to free flow. Second stages in pre-dive mode WILL deliver breathing gas, but with some increased breathing resistance because the venturi assist feature has been disabled. On the primary second stage, you should push this lever in to the dive position (+) when you put the regulator in your mouth. On second stages not in the mouth during the dive the switch remains in pre-dive position; should circumstances require its use while in-water, once breathing from the regulator just switch the lever from pre-dive to dive mode.

The knob and the lever have related yet different functions, the knob determines how easy it is to start the breathing gas flowing to the diver and the lever determines how easy it is to maintain the breathing gas flow. Some lever designs are {predive| dive} with little or no range of adjustment to the venturi effect, however the adjustment knob by design always has a significant range of settings. Both can be set to minimize the possibility of free flow.

Some divers (especially those who use a breathing pattern called 'skipping') incorrectly believe that by using the adjustments to decrease the regulator performance they will conserve gas. In fact, improperly adjusted second stages have the opposite tendency to cause most divers to retain CO2 and increase their respiration rate thus gas usage while at the same time causing some discomfort and/or headache.

† You might be surprised to learn some experienced divers dislike having an adjustment knob on their second stage. They view the knob as an unnecessary option that is thought to be more of an entanglement hazard, certainly adds to the cost of the regulator and some just prefer a more streamlined second stage. Unnecessary? Yes, even when there is no external knob, the cracking pressure on downstream designs is always adjustable internally. This an easy skill to learn, beneficial to know, and there are videos on the internet to show you how.
