Subject: Rebreather Reply-To: tbond@p5*.nm*.fu*.co*.jp* FCC: /home/T_O/tbond/Mail/tbond --text follows this line-- Below is what could be laughingly called a "translation" of an article on the Fieno rebreather. I am not a professional translator and the result reads like a very poor english essay. I apologise but hope you can gleam some information from it. On carrying the Fieno to the 5m deep shallows it soon became apparent that the Fieno is much different to normal scuba gear in terms of weight. The unit feels only slightly heavy. When you let the air out of the BCD you start to slowly sink. Breathing remains very natural. There is some resistance to breathing but breathing is not hard. Moreover, the breathing was smoother tan expected. As you go deeper breathing trimming is not relevant to buoyancy control so you can keep on breathing normally. Because the depth is shallow you are naturally neutrally buoyant. On the seabed, at a depth of 5m I removed the mouthpiece. I replaced the mouthpiece and pressed the purge lever. The water inside the mouthpiece unit (relating to the scuba second stage) is purged. Then by pressing the start button the function of the mouthpiece is restored. This sounds a little complicated but once done underwater you will find it quite easy. When you press the purge button before the start button water is expelled from the exhaust hose. In order to ensure that the canister does not get any water in it and that you do not drink any water this complicated procedure is not necessary. By lifting the hose the water inside is automatically expelled. In fact this is the Fieno's most superior point. Whenever you remove the mouthpiece underwater athis is all you have to do. On the first dive test it was surprising how easy the Fieno is to use. The second dive was to 15 metres. On the surface I let out the air from the BCD, breathed out and began to sink. Since I was overweighted I put some air in the BCD at 10m. The operation of the BCD is the same as for a scuba BCD. In the decending position with the head up it is easy to breath and so I gradually made my way down to the sea bed at 15 metres in this way. At this depth breathing is a little difficult but it is not inconvenient. Your senses naturally overcome this problem. Once you have got used to this the gas flows freely. How about working underwater? For fun I did a handstand and did some revolutions by on my side but the breathing did not get any more difficult. I was carrying some weight to compensate for the wetsuit buy did not have to use the BCD to compensate for buoyancy much. One major point is that you do not have to do breathing trimming as in scuba. Since the gas is recycled this is not necessary. Part Two - Underwater time is coming shortly.
