Partly because the machine I'm diving is much more complicated, yes. But also, I think my perspective is from the kinds of diving I'm using it for. There are people who think "I've done more than a 100 trimix dives past three hundred feet, so I could really kick ass on a rebreather", and those are the ones I want to convice that there is no free lunch. I use the rebreather for two things: dives deeper than 300 feet, and training dives in shallow water. The dive gets much more complicated down deep because the volumetric change in the breathing loop from hunky dory to hypoxic is much smaller than it is in shallow (200 feet or less) water. The dive is the dive at any depth, but the probability of discovering a malfunction before it becomes life-threatening down deep is less than up shallow (not to mention the consequences of a malfunction are much greater down deep). Therefore, it requires more diligence down deep than shallow. Down deep is also trickier because you have to figure out more complex OC bailout options. The real dividing line is when you do a dive where it's not possible or practical to carry enough OC supply to safely return to the surface. I have a hunch when you start doing those dives with the CCR500, you'll get a good feeling for what I'm talking about. Aloha, Rich
