Cressi MC9-SC / Compact Pro (Yoke)

A compact, sealed-diaphragm travel reg with full cold-water certification, sized and priced for divers who don't want to haul a heavy rig.

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
  • Environmentally sealed diaphragm first stage carries a full EN 250:2014 cold-water certification despite the compact form factor
  • Combined weight under a kilo makes it one of the lighter cold-water-rated sets Cressi sells, a plus for travel
  • Balanced diaphragm design (Cressi's PressureSync) keeps breathing resistance consistent as tank pressure drops
Cons
  • Service pressure tops out at 232 bar, lower than the 300 bar DIN rating on Cressi's T10-SC line
  • No octopus included in the base first-stage/second-stage set
  • Also sold in a DIN version, confirm the listing matches this yoke spec

The MC9-SC/Compact Pro is Cressi’s travel-oriented cold-water reg, pairing a sealed diaphragm first stage with a light, compact second stage. It’s a reasonable pick for divers who want EN 250 cold-water certification without the bulk, or price, of Cressi’s higher-end T10-SC line.
