"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
  • Air-balanced flow-through piston keeps breathing effort constant regardless of depth or tank pressure
  • XTIS thermal insulation gives it the same strong cold-water reputation as the G260-equipped MK25 EVO
  • S600's fiberglass-reinforced technopolymer body is noticeably lighter and more compact than the metal-framed G260
Cons
  • Not an environmentally sealed design like Scubapro's diaphragm regs, cold-water performance relies on XTIS rather than a sealed chamber
  • No octopus included in the base set, budget for a second second stage
  • Also sold in an INT/yoke version, so double-check the listing matches the DIN 300 spec here

The MK25 EVO/S600 pairs Scubapro’s proven flagship piston first stage with the S600, a lighter and more compact second stage than the G260 it’s more commonly sold with. It’s a solid pick for divers who want the MK25 EVO’s cold-water durability without the bulkier metal-bodied second stage.
