The Dive is the Grand Dive's smaller sibling and the better buy if you will mostly lie down. It keeps the same clearance, the same two redundant compressors and the same two-year cover on every component.
At $9,995 plus $300 shipping it is $4,000 cheaper and still 33 inches across, wider than OxyHealth's Respiro 270.
As with the Grand Dive, oxygen is your own business and the warranty is short unless you extend it.
Best for: a lower-priced Summit to Sea chamber with the same FDA clearance and warranty.
In the box: Two redundant compressors, external frame, foam mat, four foam bolsters, two viewing windows, carrying case.
The catch: Not wide enough to sit up comfortably like the Grand Dive, and no oxygen concentrator is listed.
The Dive lists at $9,995 with $300 shipping in the 48 contiguous states, on the same price table as the Grand Dive. The extended warranty is cheaper too, starting at $1,000 for one to three extra years. The 10% discount for military, first responders and firefighters applies across the range, according to Summit to Sea.
At 33 by 90 inches, the Dive gives you about an inch more width than the Vitaeris 320 and six more than the Respiro 270. That is enough to lie on your side and bend your knees. It is not enough to sit fully upright, which is the main reason people pay up for the Grand Dive. The Dive comes with an external frame, foam mat, four foam bolsters, two viewing windows and a carrying case.
Summit to Sea lists a double vent system capped at 4.4 psi, two redundant compressors and zippers that open from inside or outside. That covers the two things most new owners worry about: running out of air if a compressor quits, and not being able to get out without help.
