Scubapro MK17 EVO 2/S620 Ti (DIN)

Scubapro's top-tier sealed diaphragm regulator, built with a titanium second stage for divers who want cold-water-proof performance without piston-reg bulk.

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
  • Titanium second-stage barrel trims weight and work of breathing versus the outgoing S600 design
  • Fully sealed dual-diaphragm first stage is EN250A rated for genuinely cold, silty water
  • Two angled HP ports and four LP ports keep transmitter and hose routing clean
Cons
  • No octopus included at this price point, budget for a second second stage
  • Premium pricing puts it well above the mid-tier MK11 EVO/C370
  • Recent design means a shorter field-reliability track record than Scubapro's older MK-series regs
Diver community sentiment
Mostly positive

Across several Scubaboard threads, divers consistently praise the MK17 EVO 2/S620 Ti as a premium, reliable cold-water and technical-diving setup, citing effortless breathing even in 30-40°F water and comparing it favorably to Scubapro's other MK-series combos. Several long-time owners report years of trouble-free use and note the titanium S620 Ti's superior build quality over the S600, though it commands a real price premium. The main recurring complaint is out-of-box quality control rather than in-use performance: at least one diver reported significant intermediate-pressure creep and a rattling trans-piston on a brand-new unit; consensus among experienced posters is that dealers should pressure-test and tune new Scubapro regulators before handing them over.

The MK17 EVO 2/S620 Ti sits near the top of Scubapro’s regulator line, built for divers who dive cold, silty, or otherwise demanding water and want a compact, fully sealed first stage paired with a lightweight titanium second stage. It’s the natural step up for divers who’ve outgrown a mid-tier reg like the MK11 EVO/C370. Also sold in an INT/yoke configuration.
