Mares Dual ADJ 62X 75th Anniversary Yoke Regulator

Mares Dual ADJ 62X 75th Anniversary Yoke Regulator: A High-Performance First/Second Stage Set with Collector Appeal

The Mares Dual ADJ 62X 75th Anniversary is a complete scuba regulator set, pairing a balanced diaphragm first stage with an adjustable second stage, finished in a limited-edition commemorative design.

If you are a recreational or advanced diver who wants genuinely capable breathing performance and also appreciates owning something that marks a moment in diving history, this regulator is worth a serious look.

If you are purely shopping for everyday workhorse gear with no interest in the collectible angle, a standard version of the 62X will do the same job for less.

What You Are Actually Getting

This is a yoke-mount (also called INT or A-clamp) configuration, meaning it attaches to the standard valve fitting found on most rental and recreational cylinders worldwide.

The set consists of two main components:

• 62X first stage, a balanced diaphragm design with 2 high-pressure ports (7/16" UNF) and 4 low-pressure ports (3/8" UNF)
• Dual ADJ second stage, with adjustable breathing resistance and VAD (Vortex Assisted Design) technology
• A Superflex hose at 29.53 inches (75 cm)

The first stage weighs 26.2 oz (742 g) in this yoke configuration. The second stage adds 6.7 oz (185 g). Both are built from Mares' ultralight technopolymer, which keeps the overall weight manageable for travel.

The First Stage: Balanced Diaphragm Explained

A balanced diaphragm first stage means the regulator delivers consistent intermediate pressure to your second stage regardless of your tank pressure dropping as you use your air.

In practical terms, your breathing effort stays steady from the first breath of a full tank to the last breath before you ascend. You do not feel the regulator working harder as your cylinder empties.

The 62X has four low-pressure ports, which gives you enough flexibility to route a second stage, a drysuit inflator, a buoyancy compensator inflator, and a pressure gauge or transmitter without needing an adaptor.

The Second Stage: What the ADJ Knob Does

The "ADJ" in the name refers to the adjustable breathing resistance dial on the second stage.

Turning it up adds slight resistance to inhalation, which is useful at the surface or in choppy conditions to prevent the second stage from free-flowing (delivering air continuously without you breathing). Turning it down gives you the lightest possible breathing effort at depth, where the surrounding water pressure already helps keep the diaphragm stable.

This is a practical feature, not a gimmick. Divers who move between warm, calm water and cooler or more demanding conditions will use it regularly.

The VAD (Vortex Assisted Design) system routes incoming air through a bypass tube that creates a low-pressure zone at the diaphragm. The result is a second stage that responds quickly and smoothly to inhalation without requiring extra effort from you.

DFC (Dynamic Flow Control) works alongside VAD by reducing the pressure drop that occurs when you inhale hard, keeping gas delivery consistent even when you are breathing heavily during exertion or at deeper depths.

Durability and the Black Intense Coating

The first stage body carries Mares' Black Intense ceramic coating, which is described as resistant to scratches, corrosion, chemicals, and UV exposure.

This matters for a regulator that lives in a dive bag, gets rinsed in communal rinse tanks, and occasionally encounters sunscreen, boat fuel, and saltwater. A finish that holds up to that abuse means the regulator looks presentable for years, which matters more than usual on a collector piece.

The Anniversary Details

The commemorative elements are specific and tangible, not just a logo on the box:

• A sequentially numbered bolt snap, so each unit in the limited run has its own number
• A custom second stage shell carrying the 75th Anniversary metal logo
• A pearl chrome-plated ADJ knob
• A chrome-finished frame around the purge button
• Premium anniversary packaging

The sequential numbering is the detail that makes this genuinely collectible rather than just cosmetically different. If you care about provenance, that matters.

Conditions and Fit

The technopolymer construction indicates this regulator is suited to warm and moderate water temperatures. The key features also note cold-water rating, so it is not limited to tropical diving, but if you regularly dive in genuinely cold water (below around 10°C / 50°F), confirm with your local dealer that this configuration meets your specific needs before committing.

The 75 cm hose length is standard for recreational single-tank diving. If you dive with a long-hose configuration for overhead environments, you would need an aftermarket hose.

Who This Regulator Is Not For

Technical divers running stage bottles or needing DIN fittings for high-pressure cylinders will want to look at the DIN version or a different regulator entirely. This is a yoke set.

Divers who want the most anonymous, no-fuss workhorse and have no interest in the anniversary story are paying for design and packaging they will not appreciate. The underlying 62X platform is a solid recreational regulator, but the standard version achieves the same breathing performance without the commemorative premium.

A Note on the Platform

The 62X first stage has been part of Mares' lineup long enough to have a real service history behind it. That matters when you are choosing a regulator, because parts availability and technician familiarity both affect long-term ownership costs. This is not an exotic or obscure platform dressed up for an anniversary. It is an established design in a special-edition wrapper.
