"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 S620 Ti second-stage barrel and inlet tube trim noticeable weight and bulk off the standard G260 pairing
  • Air-balanced flow-through piston first stage keeps breathing effort steady across depth and tank pressure, the same proven MK25 EVO platform Scubapro uses across its line
  • Enlarged Hi-Flow mouthpiece and a large diaphragm give it a soft, low-effort draw that stands out in a shop comparison
Cons
  • Priced well above the standard MK25 EVO/G260 combo for what is mostly a second-stage weight and material upgrade
  • Also sold in an INT/yoke version, so double-check the listing matches the DIN 300 spec here
  • No octopus included in the base set, budget for a second second stage separately
Diver community sentiment
Mostly positive

Across several Scubaboard threads, experienced divers consistently describe the MK25 EVO/S620 Ti as extremely reliable, easy-breathing at depth, and "bulletproof," with long-term owners reporting years of trouble-free use in cold and warm water and easy worldwide serviceability. Recurring gripes are about servicing rather than the design: a high-pressure squeal or IP creep occasionally shows up right after a rebuild, usually traced to lubrication or a tech unfamiliar with balanced diaphragm regs. A few posters call it overpriced for recreational diving and note the titanium weight savings over the standard S600 are negligible. Independent testers (ScubaLab) gave it a Tester's Choice award.

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

The MK25 EVO/S620 Ti takes Scubapro’s familiar flagship piston first stage and pairs it with the smaller, titanium-trimmed S620 Ti second stage instead of the bulkier G260. It’s aimed at divers who already trust the MK25 EVO platform but want a lighter, more compact second stage for travel or long days in the water.
