Sherwood SR2: Picture 1 regular

About Sherwood SR2

The SR2 Regulator continues the legacy the SR1 created. It packs advanced technology into a compact case, employing contemporary-styling and utilizing a multitude of cutting edge materials to bring to you a superior high performance regulator system. Superior breathing performance the SR2 is more technically advanced and more attractive than its predecessor. The SR2's first stage regulator is one of the only truly" balanced first stages on the market today. Most balanced piston regulators come close, but never actually become truly" pneumatically balanced. They attempt to, by creating a very sharp knife" edge piston sealing surface that cuts into the first stage seat. This cutting of the seat deteriorates the seat rapidly lower regulator performance over time.

Sherwood addressed this problem and eliminated it! By making a two-piece first stage piston they were able to increase the seating surface sealing diameter without using a knife edge sealing surface. Not only were they able to eliminate the excessive wear associated with knife edge pistons, they were able to create the first truly" pneumatically balanced flow-thru-piston first stage regulator. This piston design provides high-flow capacity and rapid response to second stage demand as never experienced in the past.

Piston regulators inherently allow water to enter the main spring cavity to properly-adjust themselves to the ambient (surrounding) water pressure. This design also allows contaminates found in water to also enter. Sand, salt, silt and chlorine can rapidly deteriorate first stage performance. Most piston regulators eliminate this problem with packing the main-spring cavity with thick messy grease. The grease transmit's the pressure changes to the mechanism and in theory keeps the mechanism cleaner. The grease has some drawbacks such as it can leak-out" the holes in the first stage body and it also acts as a fly-trap" allowing contaminates to stick to it.

Sherwood also address this problem. By creating a sealed dry spring chamber that prevents water and contaminates from entering the regulator interior, Sherwood was able to keep the intricate internal components free of contamination from ambient deposits of minerals and Increase Performance of the regulator system. The SR2 first stage has 5-low pressure (LP) ports on a 360° swivel and 2-high pressure (HP) ports for optimal hose routing. The first stage regulator is manufactured from marine grade chrome plated brass and is nitrox ready up to 40% out of the box"

The SR2 utilizes a pneumatically balanced second stage. The second stage contains a SMART demand lever and floating crown which reacts to depressurization and relieves the load on the seat, extending seat life while promoting consistent performance. Importantly, the second stage employs a unique single adjustment point to simultaneously set opening effort and high flow performance with one-motion; the need to make separate adjustment therefore has been eliminated.

The size of the SR2 control knob has also been optimized to enable easy location and operation, even for a diver wearing gloves. The SR2 second stage has an ergonomic shape and size and is weightless in the water for maximum comfort. Regulator comes equipped with a 3/8" threaded 31" (78.75cm) low pressure hose; owner's manual and is covered by a 24 month limited warranty with optional free parts for life program (restrictions apply).

My new upgrade


from Austin, TX, US

I have been reading reviews and weighing the options for a month or two. the SR2 was not always on the top of each list but it was listed in every list I came across. It is smaller and lighter then I expected which was a very nice surprise. I personally didn't find any issue with the mouthpiece, referenced in another review, it works well for me. The 1st stage is a little on the heavy side but that should be expected since it does swivel. LeisurePro had it listed at a price that I couldn't turn down and I couldn't be happier. I will be hitting the water again this weekend to really put it through the test, or at least to my level.


Easy breathing!


Standard mouthpiece is too small, uncomfortable, and comes out of the mouth too easily. Otherwise, I love the SR2.

Questions about this item:

Shopper  Why Did You Choose This?
BOBBY S  I love my old Sherwood gear. However, I have noticed over the past two summers that it has become more difficult to breathe at depth and results in using air faster (less bottom time). Have a friend with the new version of regulator and he is very happy with his.
Shopper  For this product, would you receive 1 or 2 second-stages?
ROBERT S  1 1st stage and 1 2nd stage. This is a great Regulator!
BOBBY S  I received only one.
Jen S  Is the SR2 considered suitable for cold-water diving (such as ice diving)?
hanyao w  yes
Ben T  The first Stage is sealed however this would be a better choice.
