I have been interested in rebreathers for a bit. I had the option of going and doing a Drager Dolphin Demo up in Washington a while back and I got to do a couple dives with an SCR. Simple as could be, Crack a valve and go play in the water. I thought that was the coolest thing since the invention of the diving bell. It had Tons of bottom time (with the proper sonic valve) and there was not a lot to worry about (Except sucking spit out of the mouthpiece)
SO I went home and I read up on Rebreathers. But when I was doing my research, I found SCR's and CCR's. Now, everything seems to be either ECCR's or MCCR's with absolutely no mention of SCR's except for a few questions about the Dragers.
Now, My Local dive shop still sells the SCR, but I am noticing most people go OC - SCR - CCR, so I am thinking to myself. WHY? If a SCR will do Rec Depths for 4 hours with little to worry about managing a dilutant or Oxygen Partial pressure.. Why would someone who is doing Rec Diving move from a SCR to a CCR? If the Progression is to move to a CCR, why not just go straight there?
Also my Dive shop who does not sell CCR's, tells me that they are dangerous, twice as expensive to purchase and maintain, and are more complicated. (Ok, I know their agenda.. they want to sell me an SCR)
Forget about the dangerous aspect, that has been beat to death on this board and others.. Twice as expensive (6k vs 8-10k.. Ehh.. Whatever.), but more complicated seems to be true, even for the KISS.
What is the general take, Why is the SCR the Proverbial "Red Headed Step Child" of the Rebreather world?
