Oceanic regulator design has come a long way since its debut in the early 1980s. Technology along with diver expectations have established a precedent for what we consider precise and perfect in today's world of diving. Oceanic understands this clearly as it introduces the EOS regulator to the lineup.

For over 30 years the engineering 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.

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.

FEATURES:
The FDX-10 is an environmentally sealed, over-balanced diaphragm first stage featuring two high-pressure and four low-pressure ports, all angled to optimize comfortable hose routing. It also has DVT to protect the first-stage inlet. The new pneumatically balanced EOS second stage offers a light compact body with user controls—a large low control adjustment knob and ratcheting dive/pre-dive switch—as well as an inline swivel and a sizeable front purge cover.

PERFORMANCE:
Underwater, the EOS midsize second-stage was light and comfortable in the mouth with a swivel that tracks small head movements, reducing jaw fatigue. The patented dynamic Adjustment low control knob allows you to lock in your ideal breathing resistance, and once set, the reg compensates for depth changes. Underwater, it worked well, maintaining easy breathing at depth. The Venturi switch has a ratcheting movement for fine-tuning and the large front cover purge was easy to find. On the ANSTI breathing machine, the EOS FDX-10 produced a mix of Excellent to Very Good scores in the four test categories.

BOTTOM LINE:
This regulator comes fully loaded with all the extras and above-average breathing performance.

WEIGHT:
2 pounds, 10 ounces.
