    Nice starting point for a HomeBuild Sidemount unit...

    Just spotted this on e-bay... http://cgi.ebay.co.uk/Frog-rebreathe...QQcmdZViewItem

    Could be a nice starting point for a sidemount/bailout unit, due to the design with internal counterlung, and a small scrubber size.

    You know me too well!!

    I reckon John should get 2 of these, and strap them to his Poo-Bin to give him the triple redundancy that he seems to be striving for!

    CCR2000, Megalodon, Homebuilt

    Norge, FGT, mk15, KISS, Inspo

    everything about this one says to me that it is a fraud. This auction has been up before, the location is in London germany and finally the price, its too cheap.

    Arrr the Frog - it was with difficuly I maintained a straight face @ DEMA whilst being told that their scrubber got a guaranteed 2 horus per pound of scrubber(4 hours form their 2 pound scrubber) regardless of depth and they had tested that to Navy protocols!

    I'm not disagreeing that that does sould like rather far fetched figures. It's still quite a tidy design.

    I did have a thought about the design though... Is it effectively a pendulim rebreather? Do you breathe out, through the scrubber, into the counterlung, then breathe in the gas from the c-lung, back through the scrubber a second time?

    If this was the case, I could see how a such a tiny scrubber would work, as it can work on the gas twice - any CO2 that passed through the first time (due to short dwell time perhaps) would get a second chance at being scrubbed?

    Maybe I'm talking bollocks...

    I am not sure about that. I was told that the penudulim design was very inefficient, so inefficent that it was taken off the market, I am supprised that there is still a manufacture using it.

    The Pendulum design I have been told is very very efficient - in fact Gordan Smith, used it as the inspiration for the way he designed the Sport Kiss scrubber.

    I have talked to Gordon about how that works and it is most effecient when it comes to a persons normal use even whilst working, at a constant high flow rate with high gas velocity is becomes slightly less efficient (basically the corners done get used).

    Question

    According to Jeff Bozanic "Mastering Rebreathers" Cp 7 p. 172 par. 2

    Pendulum axil flow canisters pass the gas back and fourth thru the canister allowing the absorbant at both ends to effectively scrub the gas. However, this design had a large dead space in the breathing hose, and its use has been discontinued in modern rebreather designs.
