Sherwood SR2 (DIN)

The current flow-through piston flagship that replaced the long-running SR1, still built around Sherwood's sealed-and-dry first stage.

Environmentally sealed

Sealed first stage chamber, protects against ice formation and contaminants in cold or silty water.

"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
  • Sealed AND internally dry flow-through piston first stage, a combination Sherwood markets as unique to this design
  • Single-point adjustment sets both opening effort and flow in one motion, quick to dial in dockside
  • 5 low-pressure ports on a 360-degree swivel give flexible hose routing for stage bottles or backplate rigs
Cons
  • Direct successor to the discontinued SR1, so used SR1 parts and service support are getting harder to find
  • Also sold in a yoke version, confirm the listing matches this DIN spec
  • No octopus included at this price, the SR9952 octo is a separate purchase
Diver community sentiment
Mixed opinions

Diver sentiment on Scubaboard is sparse but real, and split. The most detailed firsthand report (a diver with 1000+ dives testing the SR2 in Curaçao) described flawless, effortless breathing over multiple dives, and other posters over the years have praised the SR2's dry-sealed balanced-piston design as underrated. Countering that, one long-time poster flatly said he "hated" the SR2 without elaborating, and a separate thread documents a unit with abnormally low cracking effort traced to a micro-adjuster mechanism that binds and strips easily, treated by the community as a possible defective unit rather than a universal flaw. There's also recurring concern that the mostly-plastic second-stage housing may be less desirable for serious cold-water diving than older all-metal Sherwood models.

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

Sherwood’s own flagship line for years was the SR1; it’s now discontinued and the SR2 has taken over as the current top-tier piston reg, carrying forward the same environmentally sealed, dry-chamber design with an added “Three Pin Link” mechanism. It’s aimed at divers who want a piston reg that shrugs off silt and cold without the maintenance hassle piston designs are usually known for.
