halcyon rebreathers

No comment on that particular SCRB. They are all a much of a muchness, just a controlled nitrox leak and and a scrubber to help extend the gas. You need some extra way of measuring the PPO2 to be safe, and if your doing that you might as well get the machine to control the O2 inject and go CCRB

You can get a cheap SCR by exhaling and rebreathing your breath 3 times from your BC via the mouthpiece. Thats a 3x extension of your gas (and its works, I've done several 20m dives this way, 4 breaths gave me a headache due to the CO2), Tip some Sofnolime in the bottom of your BC and you might even get a 5x extension (only kidding). SCR gives you about 10x

CCR not only gives you the 30x plus saving on gas, but the controlled environment gives you a much better deco window

Here in Europe we have little choice unless we import from the US. To be legal to sell in Europe a unit must meet CE testing and standards and only the Dreager SCR's and the Inspiration have this approval currently. Others are undergoing this testing, but most units wont pass as it without major mods as it has some very stringent inhalation and exhalation resistance criteria

I can't seem to find them anywhere on that page.

That is besides the point though.

I know the pros and cons of SCR vs CCR, I would like comments on that specific rebreather though. The only thing in this thread that someone says even regarding that rebreather is they have heard nothing good about them, or that they are only for the DIR boys because they have no choice.

If WKPP wanted to use all Inspiration rebreathers, they could. They have reasons that they choose not to, it is simply not because they are not sponsored by them. They do use other gear they are not sponsored by.

I don't want to hear, that someone has heard nothing good about them, I want to hear what people know to be bad about them. Again, aside from the fact that they are SCR.

Youre right, they are no longer on there I could have sworn they were last week, cos I actually went there to check before writing the first post. Must be going senile or all that diving has done me brain cells in (Didn't have many to start with)

I agree that nobody here seems to have specifics on that unit. I certainly have never handled or seen one in the flesh to pass comment. I've have dived the Ray and Dolphin however (like many) so can make general SCR comments

One of the problems is that several of the more esoteric rebreathers out there only have10 or so units in existance so unless you e-mail GI ("we're not worthy, we're not worthy")directly for his feedback you'll probably be out of luck. Try mailing the manufacturers directly as they may be able to point you to someone who has hands on

It would be interesting to poll the folks on this forumn as to what RB's thay actually have. Reletive sales numbers are very scarce

Maybe I am going to have to join the tech list and ask about them. I wish someone here had some experience with the unit.

Looks like they are using a KISS valve system.

I just did emailed him and asked him.

GentleGiant,

Dive Rite is in the process of building a rebreather. I have heard many things about it being put on hold for a little while. I have not heard if it is CCR or SCR as a definite though. I seem to recall it being an SCR, but again, I am not sure.

Didn't the WKPP team use Cis-Lunar rebreathers at some point. I seem to recall seeing that Cis-Lunar had at least done some testing with some of the WKPP folks. I might be wrong though.

On another matter I had heard somewhere that Dive Rite was working on a CCR unit. Does anyone have any more info on this?

During the Wakulla 3d mapping project Redundant loop equipped Cis lunars were used

The WKPP has never used Cis-Lunars. The Wakulla2 project, Bill Stone's project, used Cis-Lunars.

Accomplishments of that project include:

1 Bent Diver
1 Toxed Diver
1 Dead Diver

You'll find it all on the Wakulla2 project page: http://www.wakulla2.org/

Thank you for correcting my error Roakey, I appologize for getting WKPP and the Wakulla2 project mixed up. I do want to point out a couple things about your final statements though:
1. The DCS case occured near the start of the mapping project when the team was still refining procedures and did not have the chamber in place yet. Given the number, depth and length of dives though 1 DCS case is actually a pretty good feat. The diver recovered after the chamber runs and I believe he was diving again within a couple weeks.
2. The CNS Tox hit happened to a National Geographic photographer who was not part of the actual Wakulla2 team and was not using a rebreather.
3. The death occurred from natural causes as stated in the medical examiner's report, not diving related injury.

I gleaned the above from the Wakulla2 website daily reports
