Two soft chambers, $5,905 apart. Here is which one to buy, and for whom.
Short answer
It is close: both score 9.0/10, and the Grand Dive edges ahead on the raw formula, mostly on interior diameter and price (dated, us); the Vitaeris 320 hits back on warranty. Pick the Grand Dive for the most room inside: a 40-inch soft chamber you can sit up in. Pick the Vitaeris 320 for buyers who want the best-known soft chamber name and a five-year warranty.
OxyHealth Vitaeris 320
The soft chamber most clinics recognize, with the longest warranty in its class.

Pick the Vitaeris 320 if
