Cressi T10-SC / Master (DIN)

Cressi's premium sealed-diaphragm reg, built for cold water and heavier use than the compact MC9-SC line.

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
  • Hyper-balanced, watertight sealed diaphragm first stage rated to EN 250:2014 for genuine cold-water use
  • Master Ellipse second stage adds a heat exchanger on top of the sealed first stage, a second layer of cold-water protection
  • DIN fitting rated to 300 bar, useful for divers filling from higher-pressure tanks
Cons
  • Costs meaningfully more than Cressi's MC9-SC line for a similar core sealed-diaphragm concept
  • No octopus included in the base set
  • Also sold as a yoke/INT set rated to a lower 232 bar, confirm the listing matches this DIN spec

The T10-SC/Master sits above the MC9-SC in Cressi’s lineup, built around the same sealed-diaphragm concept but with a heavier-duty first stage and a heat-exchanger-equipped second stage. It’s aimed at divers who want a dedicated cold-water rig rather than a do-everything travel reg.
