I like Rule Number Three: "Don't Use a Rebreather Unless You Don't Need To" (Maybe a typing mistake, but the double negative means: "Use it anyway"? Shouldn't it be: "Don't Use a Rebreather Unless You Need To"?) Now that the spelling is checked, I would like to know if I need one or not. I want to dive some wrecks in the Mediterranean, until now we did everything with open circuit scuba. The gas logistic is slowly getting to be a nightmare. It is not only the tanks you have to carry on yourself, but the large qty of He and O2 tanks we have to transport and move back and forth from the gas suppliers and the dive center. The price is another factor, helium is not everywhere as cheap as in Florida. For the deeper wrecks we need so many tanks, that is very impractical to move on the boat, and not very healthy to swim at depth. And if the weather changes, climbing back on the boat is almost impossible. I want everybody in the team to be self sufficient, i.e. we carry all our gasses. We need a machine that can perform the dive and the decompression, and that has a bailout system. We are happy to find the boat again, but we are ready to perform our decompression drifting alone. We have found some virgin wrecks from the second world war, but they are pretty deep. There shallower one is at 95msw/311 feet, and the deepest one so far is at 160msw/525 feet. Ballard has found some interesting at 750msw/2460feet, but that's too deep! Do you think that an Halcyon with the proper training, could be a helpful tool? I think so, but I never used an Halcyon, so I cannot really judge for myself.
