Good stuff, I'm glad to see this progressing along as planned.

Thanks for the update.

Geeze Jeff, that'd be the first pics of an Eagle that I've seen without it firmly attached to your back!!!

Thanks for the writeup and the news Steve, looking forward to hearing more as it happens!

90 min a chamber with Pearson - and you all survived amazing

Nice looking unit.

Looks a nice compact unit. Nice pics too. Good post and greened.

Are scientific results going to be published, or just the impression people get from user trials?

Things like hydrostatic pressure, WOB under pressure and CO2 breakthrough have well established tests for. If it is to be sold, imported or used commercially in Europe, then the tests are in EN14143. These use breathing machines under reasonably well defined conditions, and set minimum levels for safe performance. It would be good to see the figures from Cochran rather than figures from somewhere else after the first units are sold. What are the plans on this?

Just looking at the 10mbar, and 6mbar, please could you clarify if this is in air or heliox. EN14143 would have the hydrostatic in the prone position added to that but I can't see the CLs in the pics. How big are the CLs?

Alex,

At this stage I dont believe that Colkan are looking to get a CE rating - but that may change in the future -

We will share results as much as we can there is really nothing to hide - but I guess above all else the feel and useability of the unit are the key issues - in the end if it breathes like a dog then it breathes like a dog etc - and that is often a thing you can onlyreally find out by getting wet.

Before they are released into the wild we will be doing alot of in water testing and I (we ) will keep the board fully informed of our observations. Actual measurments will be taken wherever possible.

As for further testing you would have to ask Colin. Im sure that super dooper testing comes at a significant premium and I cant speak for Col but I think that it is important to get units in the market at a reasonable cost - it is based around a Biopack 240 which does have testing.

The breathing resistance results are just a quick snapshot - it was done on air.

We did tests at 10m, 20m, 30, 40m and 50m - stopping at each depth for a few minutes and at 50m for about 10 minutes. We kept records and a table of the results - this needs to be dumped in a spreadsheet as yet.

Got it all captured on the VR3 as well -

The counterlung is under the centre section aka MK15.x series.

The chamber is at a constant pressure from top to bottom so position in this instance doesnt make much difference. However for the record the counter lung and chest hight were the same - see the picture of the 3 of us in the chamber.

Thanks for the questions,

Will keep you all posted as we generate the info.

By the way, is the last picture inverted or is that clock an Ozzie downunder thing ... ?

Well spotted Stefan - it actually takes a bit to read it quickly -

Great to see the testing is comming on well. Thanks to Steve for his effort in keeping us all informed. I can't wait till I get some units here in Melbourne.
