Its also important to note that the standars were a bit diferant than other testing. (75 RMV, 25bpm) so comparissions are not easy to make.
Question: doesnt EN specify RMV and BMM? Why each manufacturer is testing at diferant specs???

the worst CE test is exactly that: 75 RVM, tidal 3l, so 25 bpm

clear that in the wob test they all fail!! :-)

not only the WOB must be below 2.75 j/liter, but also the inhale pressure and exhale pressure must be less then 25 mbar (and they all exceed that value)

and what we surele miss it the CO2 test of the MEG scrubbers according to CE specs!

Results: The Juergensen Hammerhead CCR system failed the Electrostatic Discharge. Test. Unit lost dive data, calibration of the PO2, and millivolt output of the primary display. The primary hand set will not turn off unless the battery is removed. The unit failed to display proper PO2 and millivolt output after EMI/ESD testing and post pressure pot testing. It did not display the proper PO2 at corresponding depths. See pre and post

I told him but he wouldent listen

I am curious to know if my Primary was being knocked out by my HID

Cirtainly the end result was the same but I am asming from this test it totaly fried the hand set.

I like the old Tesco trick as well. Where they tell you the price per Lb on a pack of five and the price per Kg on the single item so the comparison is not obvious

The Radial scrubber "only" lasts 2hours 25mins where as the meg lasts 110mins.

So thats 35mins or 30% longer then using apx 30% more lime

Oh and good use of the derogatory word "only" to manage expectations

Where as they use words like "Efficient" and "Impressive" when discussing the Meg can

Still I am nit picking. I am glad someone went to the trouble of doing the tests and publishing the results. I shouldn't be surprised that a bit of gratuitous marketing was thrown in for good measure. I just wish they would credit us with enough intelegance to draw our own conclusions.

My goodness Mark, be very careful! You wouldn't want to be labeled as a traitor now, would you?

Remember, if you're not with them, you're against them ...

These results do answer one thing for me. I have always wonder how easy a prism scrubber breathed in a Meg. From the test it looks like it did very well.

That's what I was thinking. I also wonder how it would do in the meg for duration. To bad they didn't test it. Or didn't post the numbers.

Now, I don't think the Prism scrubber is as durable. But, It might be more efficient. I'd really like to see an actual comparison.

why not test the cartridges on the deeper dive-might it prove embarrasing?

Same here for me Mike. Sanity breath, then to OC.

Guys, why just sanity breath? The OC components on the Golem are interspiro and Apeks and should perform the pretty much the same as (in my case anyway) a P-port Apeks reg surely?

I can understand using the goo 'ol paragon as a sanity breath only (although even then it's pretty marginal), but the Golem?

I briefly read the tests (the higgeldy piggeldy mixture of metric and imperialism is just too confusing - they should use one or the other) but if you or Dr Mike can help out with a bit of clarity on the exact issue re the OC bailout side of things I'd appreciate it..
