Every breath 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. Comprised of precision-machined components and extensive research and design, the EOS regulator has achieved an incredible feat%u2026lifelike breathing. Oceanic%u2019s 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.
