So what's your point? That you are infatuated with air testing in Canada? As I mentioned early on in this thread and was actually on topic, in the years I was at Aircheklab I never once saw a Rix over thousands of tests. Lots of Jordairs, some Bauers (that may or may not have been Jordairs at...

I really didn't care who wrote the standards or what their bias was. I just know I made a shlit ton of money off it running a lab that did the analysis. It may be hard for you to accept that Rix is a non-entity in the world I lived in but that's what it was. Maybe get better at marketing and...

The oil field guys seemed to use mostly the same as the fire departments as the end user was pretty much on the same gear; Scott air paks or the equivalent. Maybe I didn't see any Rix's because they aren't readily available up there. Going by this thread I get the impression that a lot of the...

I don't work there anymore so I don't have access to that info.. We didn't test boosters. As I said we tested the air from breathing air compressors.

Oil mist is never a concern unless someone is running a real junker of a compressor. The reason for testing is that It's a mandate from the various provincial Occupational Health authorities and their big worry is CO. If I ran my compressor in an urban environment that would be something I would...

Air testing for scuba shops, fire departments, oil field safety companies. I saw around 1000 tests per year from high pressure breathing air compressors. Not a Rix amongst them.

99% of the people that buy compressors do just that. They "Buy something else". Outside of Scubaboard with its' local Rix shill, I've never ever heard of Rix compressors and I've been in a business where I dealt with hundreds of compressor owners every year. Never ran across a Rix. Rix is a...

I've only had support divers on a couple of occasions. One was in Halifax NS around 20 years ago and we were on OC doing 230-310' dives. The support diver was advanced nitrox trained. I recall he dove with doubles with 32% and had a cylinder of 50% in case we needed it. He may have had O2 as...

The owner of a dive shop I worked at many years ago called the AOW course "Pay me to take you diving". He loved when people would sign up. Big bucks, no whammies.

None.

i thought that European tanks didn't have burst disks?

Get a decent compressor and maintenance is minimal. Filters. Maybe oil once in a while, depending on how conservative you want to be regarding hours between oil changes. I've heard anywhere from 50 hours to 500 hours (from a compressor tech I worked with).

2 x 150-200' dives per day is pretty standard in the Great Lakes and Bikini. Bikini was 2 hour-ish run times. 4 hour surface interval is mandatory with Dirty Dozen on their Bikini and Truk trips. I think we did 90 minute run times (because of the cold) with 90 minute surface intervals in the...

The sorb or the wife?

So George was wrong? They may not be designed to rotate but they can, to a certain extent without failure, as I found out many years ago when I impacted a ceiling in a wreck while scootering. I dive OC doubles maybe once or twice a year. If the current thinking is to lock them, then I will go...

I'm in the camp that the more time you can spend on tech OC, the better your CCR skills will be. Unfortunately the cost of helium makes it prohibitively expensive to get those OC hours in with trimix. OC dives that involve deco don't necessarily need to be trimix dives. So don't jump to CCR...

They don't. You are doing a 45 minute deco stop.

I was on sertraline (Zoloft) which is also an SSRI, for a few years while still doing deep technical dives with continuous PO2s of 1.3 to 1.6. No problems for me. I suppose that is only a data point but it's a positive data point. There is no way any doc or DAN will say that what you want...

I do the prebreathe for about 3-5 minutes. To get the scrubber working, especially in cold weather, and as a final check to make sure my solenoids are working and O2 is on.

Thats is just so messed up. When I have to use Balloon grade I always analyze it first (I know a lab that does it for me for free). But I always trusted anything above Balloon grade. Looks like I better start checking every single T I get.
