Ron Mijcan suggested that I get involved in this group. My name is Dale Bletso and I have been active in the past on both the Dolphin smartgroups forum and the nwdesigns group, both of which have been real quiet for some time now.
I was one of the early coverters of a dolphin to an MCCR unit, (see
www.airheadsscuba.com/bletsop.html and
www.airheadsscuba.com/rbrsprt.html )
I have over 200 hours on the the unit CCR which I call a DOCCR or dual orifice closed circuit rebreather) I elected to use a high IP for greater depth capability and have had the unit to 67MSW and back 1200 m into a cave.
I absoluetly detest diving OC.
I am also currently working on my own design MCCR unit which would offer a better profile (more like a set of doubles) to allow me to get back into some of the caves I like to dive.
Unfortunately, I live in Kentucky, USA and most of what I see is cold, limited visibilty diving. (yes, even under the ice.)
I am a TDI IT and my bigest bitch is I can't use my "unsanctioned" unit to teach any courses. The upest is that I therefor teach less. You can see where my priorities lie.
