Description
If space matters to you — and for serious buyers, it always does — the Grand Dive delivers it. At 40 inches in diameter and 90 inches long, this is one of the largest mild hyperbaric chambers on the market, with enough room for 2–3 people or the freedom to exercise inside the chamber during your session.
Light, bright, spacious, and easy to use — the Grand Dive runs on a standard 120V / 15 AMP outlet, weighs approximately 50 pounds, and ships complete with frame, carrying case, foam mat, and dual redundant compressors. No special setup, no complicated installation, no compromises on comfort.
Summit to Sea has been manufacturing FDA-cleared hyperbaric chambers in the USA for over 30 years. Every Grand Dive ships with a 2-year warranty covering every component — because a chamber this capable deserves backing that matches.
