There is a frame that goes with it that holds whatever tanks you want. You can use whatever gas you want through a gas block that you plug the tanks into. Most rebreathers have thee as well, I know the Cis Lunar has one. The reason we use the Halcyon for long cave dives is that it is mechanical , not electronic, and all we really have to do is listen to it breathe to know it is working. If it fails, you either can not breathe, or it will not add gas. In that case we have the side tanks and we put safety bottles every 1000 feet or so. Otheriwse these devices keep yo warmer due to not blowing off the body heat thourgh your discharged gas like open circuit, and they allow more gas milage and efficiency, like being able to dive over the same safeties over and over without setup dives. The real trick to rebreather divin in the WKPP is that the guys who do it can also do the same dives on open circuit, and have done so for the most part, otherwise it is self-deception to do so - to get out of a bad deal with us, you have to be not only able to make o/c gas go the distance, which we are the masters of, but you also have to stay warm and happy and not get bent, which we are also the survivors of, adn then not tox on the long cold deco, which is key. RB is a roll the dice choice for roll the dice dives. If anyone tells you any different, they are unbaware of reality. IN WKPP there are four kinds of dives: 1) setup, 2) cleanup, 3) roll the dice, and 4) Kamikaze. Personally, I like to stay someplace between the wall and the wallpaper on this one. -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'.
