Hovey and his fellow divers spent that six-week assignment working at the relatively shallow (but still quite deadly) depth of 250 feet, and living in a shipboard capsule pressurized to the same level.

Both spaces are sealed, and then they disconnectwhats known as a transfer under pressure. Anytime seals are made or broken under that kind of extreme pressure there is the danger that a mishap could lead to an explosive decompression. On the more detail-oriented side of things, Bluetooth communication is a good idea, but most products using Bluetooth have extremely short effective ranges.
