As you did not send e-mail, I have attached a zip file to this post with the 2 files in it.
I'm a self taught RB diver & have been using my IDA71 for the last 4 years. I use a neat little needle valve that I found after months of searching. It goes down to around .5lpm & up to a max of approx 5lpm. Costs about a tenner which is pretty good in comparison to the real KISS valve.
The problem with the hard shell RB's is they are a pain to transport out of the UK, hence the reason for moving to the Ray & making it CCR. Its just a big stab really. it's also good for remote shore dives away from established dive centres, just need a couple of cylinders to decant from. This is going to be one of the smallest lightest CCR RB's around. The one thing I don't like about the Ray in SCR mode is a very light unit that has 8-10kg of lead strapped to it to sink it !
I have added a Dolphin ADV core to the Ray ADV, which does not have an SCR drilling, so you can use the Ray ADV purely for dilutant addition on demand. I have added another P-connector below the ADV in the right rear inhale counterlung, the O2 sensors fit in there. I have built a PPO2.com 3 sensor O2 monitor. I have modified a P-connector plug to carry the O2 feed from my KISS valve to the bottom of the scrubber, where an Oxygauge would normally go. Thus I get O2 diffusion through the scrubber bed.
The Ray scrubber holds 1.25kg sofnolime & I have run this for 2hrs+ in SCR mode & estimate that it should be good for 2hrs in CCR mode for shallower dives & 1hr for deeper dives. I haven't finished the O2 addition parts yet, but should have them done this weekend. I'll take some pics then & throw up a website.
Later
