Scubapro

Scubapro MK19 EVO/G260 (Yoke)

A sealed diaphragm first stage in yoke trim paired with Scubapro's biggest second stage, built for divers who want G260 breathing feel without committing to a DIN-only piston set.

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, double-spring dry chamber diaphragm design resists freeze-up and fouling in cold or silty water
  • Shares the G260 second stage with the flagship MK25 EVO/G260 combo, same largest-in-class casing and diaphragm, same reversible left/right hose routing
  • Two opposing HP ports let the first stage sit facing up or down for cleaner transmitter routing
Cons
  • Sold here in INT/yoke trim, DIN divers should look at the MK25 EVO or MK17 EVO combos instead
  • Diaphragm first stage is a different design family from Scubapro's piston-based MK25 EVO, so parts and service history aren't interchangeable
  • No octopus included in the base set, budget for a second second stage separately

The MK19 EVO/G260 pairs a fully sealed diaphragm first stage with Scubapro’s familiar G260 second stage, the same second stage used on the piston-based MK25 EVO/G260 combo. It’s a natural pick for yoke divers who want the G260’s breathing feel and reversible hose routing without stepping up to a DIN-only piston system.
