FEATURES
First Stage:
- Auto Closure Device (ACD) - keeps corrosive water out of the first stage inlet by automatically closing as the Legend is removed from the cylinder valve
- This prevents internal lubrication from washing away
- Safer for elevated percentages of oxygen
Unique over-balanced, diaphragm design results in superior performance at depth 2 HP ports and 4 MP ports are angled for optimum hose routing An environmental dry system keeps water out of the main spring chamber thus preventing ice buildup and keeping silt and contamination out Available in your choice of yoke or DIN connectors Compatible with up to 40% O2 right out of the box Second Stage:
- Pneumatically-balanced second stage results in smooth, easy breathing
- A venturi switch helps prevent freeflow at the surface and when the regulator is out of the diver’s mouth
- The opening effort is preset in a fixed position so the diver doesn’t have to worry about adjusting the regulator during the dive
- The Comfo-Bite™ mouthpiece virtually eliminates jaw-fatigue
- Heat exchanger (patented) which surrounds the valve mechanism, dissipates the cold caused by gas expansion while drawing in the warmth of the ambient water
- The ergonomic exhaust tee channels the exhaust bubbles out of your field of vision. The design also contributes to a reduction in exhalation effort
- Attached to a 29” braided Aqua Flex hose. These hoses are lightweight and extremely pliable which eliminates any tugging on the mouthpiece

WORK OF BREATHING
Did you know that it costs energy to breathe? The amount of energy
your regulator requires to move each liter of air is called work of breathing
(WOB). Lower work of breathing equals lower effort required to breathe and
increased comfort and safety during a dive.
How to Read Work of Breathing Charts
The computer-generated breathing machine chart presented above
represents a regulator's performance per standards established by the U.S.
Navy's Experimental Diving Unit. Tests are conducted at 198 feet with
approximately 3000-psi supply pressure, 25 breaths per minute of 2.5 liters
each.
(1) Inhalation - The chart shows one complete breath cycle, starting with inhalation on the left and continuing along the bottom to the right, staying mostly below 0.0; thus the inhalation work of breathing is reported in negative numbers.
(2) Exhalation - The exhalation effort begins on the right and runs across the top to the left. These are all positive numbers since a diver (or the machine in this case) is blowing out (exhaling) rather than inhaling.
(3) WOB - The total area inside the loop formed by the two lines is what the computer analyzes to calculate the regulator's total work of breathing - the amount of energy the regulator requires to move each liter of air.

WORK OF
BREATHING
Did you know
that it costs energy to breathe? The amount of energy your regulator requires to
move each liter of air is called work of breathing (WOB). Lower work of
breathing equals lower effort required to breathe and increased comfort and
safety during a dive.
How to Read Work of Breathing Charts
The computer-generated breathing machine chart presented above
represents a regulator's performance per standards established by the U.S.
Navy's Experimental Diving Unit. Tests are conducted at 198 feet with
approximately 3000-psi supply pressure, 25 breaths per minute of 2.5 liters
each.
(1) Inhalation - The chart shows one complete breath cycle, starting with inhalation on the left and continuing along the bottom to the right, staying mostly below 0.0; thus the inhalation work of breathing is reported in negative numbers.
(2) Exhalation - The exhalation effort begins on the right and runs across the top to the left. These are all positive numbers since a diver (or the machine in this case) is blowing out (exhaling) rather than inhaling.
(3) WOB - The total area inside the loop formed by the two lines is what the computer analyzes to calculate the regulator's total work of breathing - the amount of energy the regulator requires to move each liter of air.

Effortless
Comprised of precision-machined components and extensive research and design, the EOS regulator has achieved an incredible feat…lifelike breathing. Oceanic’s gifted team of design engineers has included effortless breathing, inhalation effort adjustments, and comfortable second stage swivels and orthodontic mouthpieces into a regulator that you can hold in the palm of your hand. This is far more than just another regulator in the eyes of the Oceanic team, this is a dream come true.
For over 30 years, Oceanic's R&D group has taken advantage of new materials, development of rapid prototyping, advanced computer aided design systems, objective testing, and lots of open water dives in an effort to develop a regulator with the lowest measurable inhalation effort in order to provide air to a diver at the extremes of human capacity.
When engineering brought the near complete EOS in for conformational testing the results were so astounding, the laboratory stopped testing and performed a complete calibration of all instruments, and in re-testing the EOS was found to have a near effortless inhalation resistive effort on test after test. Perfect.
FEATURES
- Pneumatically balanced second stage with virtually no breathing effort
- Diver adjustable inhalation effort
- Patented Dynamic Adjustment automatically maintains inhalation effort throughout the dive
- Ergonomic Adjustable Venturi Switch (A.V.S.) for simple Dive/Pre-Dive Adjustment
- Inline swivel for reduced jaw fatigue and comfort
- Paired with the rugged FDX-10 Over-Balanced Diaphragm First Stage
TECHNOLOGY
Pneumatically Balanced Valve.
The pneumatically balanced second stage reduces breathing resistance to near zero with a balanced valve seat designed to respond to the slightest inhalation.
A pneumatically balanced second stage actually has (or can have) the same initial crack opening effort as a mechanically balanced, but the spring force of a pneumatically balanced second stage is lighter so it’s spring rate is also lower. Therefore the force required to open the valve farther as flow increases is less than that required for a mechanically balanced second stage with a higher rate spring. So the total effort to breathe the pneumatically balanced second stage is indeed less.
The spring force must be just enough to overcome the difference between downstream air pressure and upstream balance chamber pressure.
The downstream air travels through a hole in the poppet into the balance chamber and applies an "upstream" force just slightly less than the downstream force.
Diver Adjustable Inhalation
Effort.
Most downstream demand valve regulators are
calibrated during manufacturing to a single, 'middle of the road' operation.
Whether finning up current at 100+ feet or merely snorkeling out to the dive
site, this factory adjustment may not be optimum for the wide variety of demands
we place on our equipment. A simple twist of the adjustment knob enables
complete control... Set the inhalation requirement to near zero when you need
ultimate performance, or tune it for greater resistance as conditions or
preferences change.
Patented Dynamic Adjustment.
A common objection to adjustable second stages is that
divers can't imagine themselves twisting and turning a knob as they descend and
ascend through the depths. If inhalation resistance is set near zero at depth,
your ascent would require you to manually increase resistance as ambient water
pressure is reduced to prevent free-flow. Taking another stride beyond common
second stage engineering, Oceanic designed a patented DYNAMIC ADJUSTMENT feature
into the heart of the EOS. This mechanically balanced valve maintains your
preferred breathing resistance throughout the dive. Set it once and the EOS
automatically adjusts to make breathing as easy at 100 feet as it is at 30 feet
- with no additional manual adjustment.
Ergonomic A.V.S.
(Adjustable Venturi System) Dive/Pre-Dive Switch.
Designed to be unobtrusive, yet easily manipulated even with
the thickest gloves, the A.V.S. deflector vane found in the EOS either diverts
airflow from the valve to the mouthpiece, producing effortless venturi-assisted
inhalation or creates enough resistance to prevent free flow on the
surface.
Inline Swivel.
Ever notice that nearly every picture you see of a diver,
their regulator looks like it’s not the least bit comfortable? The EOS features
an ergonomically designed in-line swivel for ultimate comfort.
Computer Optimized Design.
The EOS was designed using the latest 3-D computer modeling
techniques. This allows us the ability to model and test performance while still
in the early stages of development. The EOS’s unique valve, deflector vane and
housing design directs airflow from the valve directly to the mouthpiece,
producing nearly effortless venturi-assisted inhalation.
Patented Orthodontic
Mouthpiece with High-Density Bite Tabs.
To further
reduce jaw fatigue, the EOS features a patented Orthodontic Mouthpiece, designed
to accommodate the natural overbite of the human jaw.
Nitrox Compatible.
The EOS | FDX-10 is classified as being suitable for use
with Nitrox breathing gas mixtures containing up to 40% oxygen by volume without
the need for special preparation, cleaning or component parts.
FDX-10 Over-Balanced
Diaphragm First Stage.
The Forged from marine-grade
brass, the FDX-10 features optimized air paths and angled hose ports for
superior performance and comfort. A sealed Balanced Diaphragm design, Enviro Kit
isolate all internal components from the environment. 2 high pressure and 4 low
pressure ports allow convenient and comfortable hose routing.
The FDX-10 high performance over-balanced first stage provides progressively greater intermediate pressure as depth and gas density increases. The center “pads” that the diaphragms act against are different sizes so the working area of the outer environmental diaphragm is larger than the working area of the inner diaphragm. As depth increases, more pressure is applied to the larger surface area of the outer diaphragm than would be applied to the internal diaphragm. The result is superior gas delivery under the most extreme conditions.

In our case that challenge led directly to the ZEO.
We started with the EOS, a legendary regulator known for it's comfort and breathing profile and ended up with the ZEO. Like it's predecessor the EOS, the ZEO is also a phenomenal breather allowing the diver extensive control over the air flow profile at any depth. It takes this design one step further however by incorporating a tough and corrosion resistant chrome plated marine brass valve that has better cold water performance and even a better breathing experience. The all metal valve encourages the condensation of water vapor from your exhalation on the valve housing. When you inhale that condensed water vapor circulates with the airflow and helps to reduce "dry mouth" and increase the overall level of comfort. The ZEO also comes with our patented Dynamic Adjustment technology, diver inhalation effort adjustment controls, dive/pre-dive switch, swivel and an super comfortable orthodontic mouth piece.
The ZEO second stage comes paired with our new first stage FDX-i. The cold forged, over-balanced diaphragm FDX-i is environmentally sealed. It's in-line design limits the pressure loss inherent in "L" type first stage designs making the FDX-i more efficient and lighter due to it's compact form.
The ZEO/FDX-i combination is everything you need for a sublime breathing experience at any depth and in any environment. From the balmy tropical waters of the caribbean to the extremes of cold water diving's best dive sites, the ZEO will perform with reliability, consistency and comfort and makes taking your favorite regulator literally anywhere, that much easier.

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 transmits 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" (78.75 cm) low pressure hose and owner's manual.
