Jason,
What's the dry travel weight for the rebreather with the stainless steel ring included?
Bathroom scale says 19.0 lbs, empty scrubber. This does not include onboard O2 tanks (which is not shown in the pic anyway). Actually, with the scubber full, and the counterlung half full, it is neutrally bouyant- I can deflate it and it sinks, or inflate and it floats above the surface. Perfect for donning and doffing in cave. The ring does not come off- it is integral to the function of the unit. (I would have to completely strip the center section to take it off, and it retains the counterlung spring.)

With the K1d sensors can you use a Shearwater- or does it require R22’s for sensors. I have found that most computers want the R22 style another reason Jetsam went over to the R22 sensors on the sport units.
I do not know the answer to this, but it matters little- there is room for a triple R22 sensor block in the same place that the K1Ds are mounted- as soon as they die, I will make the block and replace them with R22s anyway.

In respect to the single counterlung which way did you run it compared to the scrubber (counterlung before or after?) I believe the standard is through the scrubber and then into the counterlung (or after the scrubber.)
Counterlung is before- this is more for the mechanics of the center section than for any other reason- The counterlung is mounted below in almost all conditions- in addition, there are ledges that prevent water from flowing upward towards the scrubber inlets if you go vertical- almost as if it was designed to run that way in the water. In addition, any possible water dumping will happen in the counterlung- though due to the shape of the OP valve, this is not really possible either- but if the unit is run the other direction, water (lung scum) from the the loop is sent directly onto the scrubber and soaks it right away. Not acceptable. Excess water in the counterlung is still a slight problem- so far it is never gotten into the scrubber, but I can definately hear it sloshing around after 4+ hours. I suppose that I should leave well enough alone in the fact that water has not yet made it to the scrubber, but on the other hand I have been tossing around the possibility of adding a water dump at the base of the counterlung. I just hate to make another penetration into the cannister.

With your current dives, how much do you estimate you are using of the scrubber as a percentage?
I would say almost 95%. I have had a number of dives where i have split the scrubber into two dives with anywhere between hours and a day in between- and always about hour 4 I seem to start getting CO2 effects, such as increased rate of breathing, but never headaches that approach what I can get OC. This may very well be attributed to using scrubber that expired in 1992. Since all that is gone now, I will revise my numbers when I get some new sofnolime next month. I have not experienced effects on a single dive, even as long as 4.5 hours. So all that is not very scientific, or even very smart, but hey.

I was curious if you were analysis what you are using of the bed.
Nothing beyond diving it and seeing what happens.

Great system and very interesting use of the push piping.
Thanks, I cant begin to impress on folks how awesome this tubing is. It just never leaks. I have regular scuba stuff that leaks more often than this tubing. Great stuff.
