DGX Gears Regulators

It is difficult to give you a meaningful answer regarding breathing performance of ANY of the primary regulators we sell, including our own DGX Gears brand, in relation to other specific brands or models we don't sell. However, perhaps we can put the performance issue in perspective: In reality, any modern balanced general purpose scuba regulator, designed to perform to EN 250 standards and properly maintained, is capable of delivering gas more than adequate for the needs of two sport divers (primary plus an octo). That's not to say there aren't poorly performing sport regulators in the market, but you can't buy them at Dive Gear Express.

There is no perfect regulator; they all have strengths and weaknesses that make each uniquely more or less suited to your needs. Keep in mind that a big brand name and high price are factors that rarely equate to better performance or better value. When choosing regulators at Dive Gear Express, make your decisions based on considerations that are less about "performance" and more about matching the regulator to the diving application. For example, an extreme exposure (i.e. deep and cold) technical diving regulator is a poor choice for shallow tropical sport diving. Beyond the features of the regulator itself, you should consider the supplier along with how the model was designed and has been supported. As an independent servicing dealer, we stock complete regulator packages, components and parts with online ordering and same day shipping.

With one exception, all the diaphragm regulators we sell are environmentally sealed, including the DGX Gears D6, Dive Rite XT1, Mares 28XR, and Apeks XTX series (DS4, TEK3, DST, FSR) first stages. The Poseidon Xstream is a unique balanced rolling diaphragm ball valve design that is not environmentally sealed because it relies upon a built in thermo-dynamic anti-freeze system to remain ice free.

Piston regulators are not typically described as environmentally sealed in the conventional sense because the internals are protected by other methods inherent in their design. The DGX Gears XTRA & FIRST, Dive Rite RG5400, and Mares R2XR are piston first stages.

The need for sealing a first stage is not relevant to most types of diving, for more information read our TekTip titled Environmentally Sealing SCUBA Regulators.

The DGX Gears XTRA is not manufactured or supplied by ScubaPro. The DGX Gears D6 is not manufactured or supplied by Apeks. Although their designs may appear similar, the DGX Gears regulator periodic service parts kits are not compatible with ScubaPro or Apeks.

The DGX Gears regulators appeal to the same target demographic of the diver looking for a top-shelf performance regulator. Like the ScubaPro, the DGX Gears XTRA has a balanced piston type first stage with a balanced diaphragm downstream type second stage. Like the Apeks, the DGX Gears D6 has a balanced diaphragm type first stage with a balanced diaphragm downstream type second stage. The DGX Gears regulators are priced a third less than comparable top-shelf regulators making them an excellent value.

Further, Dive Gear Express believes the consumer has the "right-to-repair" and our policy is to make all DGX Gears regulator service parts and kits individually available for purchase without restriction, along with the complete service manuals plus educational maintenance videos published on our website.

The short answer is that many, but not all, of our generic and DGX Gears branded SCUBA products are imported from Asia, typically Taiwan or mainland China. Sources can change as we adjust our selection of vendors and their upstream suppliers.

For a specific product, open the More Information tab on its product page and look for Country of Manufacture. This is our best available origin information, based on supplier disclosures and our knowledge of the product's sourcing. Where clear manufacturing information is unavailable, we may use a reasonable sourcing inference. The entry does not mean every component was made in that country.

The longer answer is that most SCUBA products combine materials, components and labor from places around the world. Manufacturers and distributors are not always clear or candid about this information, and origin disclosures and marketing claims can be incomplete or misleading. A brand's home country, the location of final assembly and the origins of its components can all be different. For a retail merchant like Dive Gear Express, tracing that entire chain is often impractical. In a global economy, the answer to "Where was it made?" is frequently more complicated than a single country name.

Consider something as ordinary as a rubber regulator hose. The hose stock might be manufactured in the United States using imported materials, then shipped to Taiwan to be cut to length and fitted with Chinese-made fittings and O-rings. The finished hose might then be installed on a regulator assembled and tested in Italy using parts from several countries, before reaching us through a US distributor. A "Made in ..." marking on the hose would tell only part of the story of that regulator package.

Regardless, part of the Dive Gear Express mission is to provide premium quality scuba diving equipment with favorable prices, and we are constantly adjusting our global supply chain to deliver on that mission. These adjustments can take many months and in some cases even years to implement.

The DGX Gears XTRA first stage offers an extra choice of either a typical standard 300 Bar DIN inlet fitting or a special DIN fitting that includes an auto-closure function. Our service technicians tell us one of the most common reasons for needing an overhaul on a first stage and/or SPG failure is contamination introduced while handing and rinsing the regulator after diving. The auto-closure feature (aka ACD) on the first stage shuts the DIN inlet when not fully engaged on the valve, potentially avoiding the inadvertent introduction of water and other contamination into the first stage. Although the auto-closure feature is popular it is also controversial, some divers who are meticulous with their equipment care feel the auto-closure feature just introduces another potential failure point (causing no breathing gas at all) and prefer the standard 300 Bar DIN inlet fitting. We do not recommend the ACD option for use in technical diving applications, especially where the diver may perform valve shutdown drills. The XTRA gives you the choice of with or without auto-closure, the price is the same either way.

The short answer is "yes". The FIRST regulator is a classic downstream balanced piston design 1st stage that is popular for reliability and minimal maintenance in dive shop rental fleets. This inexpensive first stage provides good performance for its design class and we have no concerns using the FIRST regulator for recreational sport SCUBA diving depth applications. However, we do not recommend the FIRST for breathing use in extended range depths or in very cold waters.

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 Product Attachments tab for service manuals and service parts kit schematic diagrams in the links below as well as the appropriate YouTube videos for do-it-yourself. ​

The only difference between our unbranded SPG "brass & glass" models and similar branded SPG models is the logo and price; any SPG will work on any regulator regardless of brand and they are all manufactured by Termo Industra of Italy with equal quality construction. Our unbranded generic SPG models have a lower retail price as a result of being sourced directly from the manufacturer. Our long experience with the unbranded and branded "brass & glass" SPG models has been they all have similar reliability and durability in the field. Regardless of brand, every product we sell is backed by Dive Gear Express 5-star quality customer service. For more information see our TekTips titled SPG Depth Ratings and Inside Submersible Pressure Gauges.

The DGX and Dive Rite inflation regulators are both compact ultra-reliable piston designs but differ significantly in performance and size of their first stages. The Dive Rite inflation package has an exceptionally compact unbalanced first stage, but only two LP ports. The DGX inflation package has a balanced first stage with a value price and three LP ports, featuring better performance that makes it appropriate for breathing applications as well as inflation. The Dive Rite package includes a {30 in | 76 cm} long rubber drysuit hose and the DGX package includes a braided flex hose in a choice of length that features our EZ-ON quick disconnect. The DGX package also includes a small pressure gauge.

The only significant difference is the branding and price; any DIN-to-Yoke adapter will reliably work on any DIN regulator regardless of brand. The designs differ a little but they are all of equal quality chromed brass construction. The generic value priced DGX adapters are available in your choice of black or silver color, and features a nice sized handwheel which makes it easy-grip to install and remove from the valve.
