Ascent rate?

[Lucy's Diver]

They have a large multi compartment wet/dry chamber so the subject can live for weeks in it and engage in dives within the chamber.

The Navy claims this chamber can press to 2250 FSW and also simulate 150,000 feet of altitude.

Wow, that's amazing! I still wonder what the deepest chamber dive would be that anyone has ever done.

gauge not working! come up on the smallest bubbles.

I would prefer to come up on my back-up gauge, which is on my buddy's wrist.

Comex's experiment, HYDRA 10 was a dive to 701 meters breathing hydreliox.

Duke's experimental dives, Atlantis III were to 685.8 meters and they spent 24 hours on the bottom breathing trimix.
