"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
  • Simple flow-by piston design is rugged and cheap to service, a common pick for rental fleets and dive centers
  • Nitrox compatible out of the box
  • Budget pricing well below Mares's Prestige and Abyss lines
Cons
  • Unbalanced, unsealed piston design makes it a poor fit for cold water
  • No adjustable breathing-resistance control on the second stage
  • No octopus included, sold as reg only
Diver community sentiment
Mixed opinions

Across several Scubaboard threads, divers describe the Rover 2S as rugged and cheap to maintain, with one longtime Mares user calling the Rover line "built like a tank" for heavy use with cheap, easy servicing, though US service centers can be hard to find. On breathing performance, commenters are lukewarm rather than enthusiastic: one poster in a comparison thread called its unbalanced first and second stage "ok" but ranked it below balanced rivals, and its main selling points were cited as simplicity and cheap parts rather than breathing quality. Consensus is that it's a solid, low-maintenance budget/rental workhorse best suited to warm or temperate water, not cold-water diving.

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

The Rover 2S is Mares’s workhorse entry-level regulator, an unbalanced, unsealed piston design chosen by rental fleets and dive centers for its ruggedness and low service cost. It’s a solid budget or backup regulator for warm and temperate recreational diving, but its unsealed piston first stage makes it a poor match for cold water. Also sold in a DIN version.
