The Deep Six DGX 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 Deep Six DGX 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 Deep Six DGX 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 Deep Six DGX 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 manufacturers recommended service interval is every two years or one hundred dives.

  1. Some minor flaws make it undesirable

    By Nathan J.

    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.

What are the differences between the Deep Six DGX and Deep Six Signature regulators?

In short, you have two Deep Six regulator choices: a REALLY SOLID time-tested regulator in value priced DGX packages available exclusively at Dive Gear Express and an AWESOME new regulator in the Signature (fka Aegaeon) available at the Deep Six Gear website.

The Deep Six DGX first stage is a proven design and compared to the Deep Six Signature first stage it's a bit larger. The DGX rotating turret won't turn 360 degrees with a hose in all 4 LP ports where the Signature will rotate fully no matter if every LP port is used. The Signature is chromed then PVD coated for greater scratch protection, versus the DGX that is standard chrome. The Signature has a Teflon coated HP poppet and Teflon o-ring in the balance chamber giving increased performance, versus the standard poppet and Viton o-ring in the DGX. The Signature has a metal DIN handwheel, versus the DGX high-impact plastic DIN handwheel. The DGX second stage and the Signature second stage are slightly different body shapes. The Signature second stage barrel is Teflon coated over chrome, the DGX only chromed. The Signature has the Deep Six exclusive Turbine Poppet, the DGX does not.

The Signature comes with a special DIN cap that has a spare DIN o-ring in it, the DGX includes a standard DIN cap. The Signature first stage is also available in a native yoke version, the DGX is available with an optional yoke adapter. Other differences are the Signature regulator ships in the Deep Six orange dry box, the DGX regulator offers the optional DGX Tek Regulator Bag. The Signature includes free service parts, the DGX does not include free service parts. The Signature regulator is also eligible for one free periodic maintenance service.
