Mares Dual ADJ 62X (Yoke)

One of the smallest first stages on the market, a sealed diaphragm design paired with a genuinely adjustable second stage.

Environmentally sealed, cold-water rated

Sealed first stage keeps water and ice crystals out of the internal mechanism, the standard for diving below 50°F/10°C.

"HP / LP ports" is the number of high-pressure and low-pressure ports on the first stage, which caps how many accessories (transmitter, SPG, inflator, second second-stage) you can run at once.

Pros
  • Compact, environmentally sealed diaphragm first stage backed by Mares' Auto Sealing Technology (AST), among the smallest first stages sold today
  • Second stage includes a real diver-operable breathing-resistance knob, not just a venturi switch, matching the "ADJ" name
  • Optional Twin Balanced Piston anti-freeze kit extends genuine cold-water capability beyond the base sealed design
Cons
  • No octopus included at nearly $500, budget for a second second-stage separately
  • Sold as separate DIN and yoke versions rather than one convertible unit, so confirm the listing matches the yoke fitting described here
  • Published weight figures vary noticeably across retailers, so travel-weight-conscious divers should double-check before buying
Diver community sentiment
Mostly positive

Scubaboard divers who discussed the 62X first stage, especially the sealed "TBP" variant, praised its intermediate-pressure stability and build quality, with one experienced poster saying it held IP within 2 psi from full tank to near-empty and calling it comparable in engineering care to higher-end Scubapro regulators. Posters noted the plain (non-TBP) 62X lacks environmental sealing and recommended the TBP version for cold or deep water. In a head-to-head thread against the Scubapro MK19/G260, divers rated the two as performing similarly, with the 62X cheaper and more compact but less sealed against sand/salt. The Dual ADJ second stage itself drew little detailed complaint, generally described as fine.

Summarized from public forum discussion (Scubaboard, Reddit, and similar), not a survey we ran ourselves. See the linked threads for the original conversations.

The Dual ADJ 62X is Mares’ compact, sealed-first-stage regulator, built around what the brand markets as the smallest first stage in the diving market and paired with a second stage that has an actual adjustable breathing-effort knob rather than just a venturi lever. Mares also sells the same second stage with the cheaper, non-adjustable Dual 15X first stage for divers who don’t need the fine-tuning.
