No. The CO is not fine. There should be zero. None. While the values are within the crappy limits that CGA allows, the values also indicate there is a problem with the supplied air. I worked in a lab that dealt with this sort of thing and I've run thousands of samples of breathing air and other...

No. There should be zero CO. Also the CO2 levels are higher than what I would expect to see especially in the 50% bailout. That number should be around 200-250ppm, not almost 600.

Canada's west coast problem- USAT Brigadier General M. G. Zalinski - Wikipedia We dove it in 2008, '10 and '12 (if my memory is correct) and I had video of oil seeping from missing rivets. The Canadian gov't did a cleanup in 2013. Whether or not it was a success, who knows? I would sure like to...

This is a Scuba forum. If you want to talk about skydiving then find another place. C'mon mods. Do better.

The picture of the gear in the original news report seems to show some CCRs on the ice and a couple sets of doubles.

I have experienced it and it's a farm animal stupid way to go about teaching civilians to tech dive. This idiot instructor should be reported and kicked out as soon as possible.

Is this guy local to you? Doesn't matter really. Run.

The Alberta Underwater Council puts on the Divescapes show every two years. This year's edition is in Calgary in October. www.divescapes.ca

When I worked at an air analysis lab we would use air to calibrate daily (yes, air is a recognized standard gas for calibration for O2 analyzers) for air and stuff and a certified 95% mix for doing pure O2. Just for fun on a slow day we did a run on nitrox mixtures of 50% and 80% using air as...

I had some of the older steel HP100s that I doubled up. There were of different heights but it worked out. I have never had a problem with aluminum cylinders from the same maker.

I'm not tracking what used Divesofts are going for, however the above statement and the fact they want yearly servicing would put me off buying one unless it was a smoking good deal. That would be my guess.

If someone is on the island and needs a chamber ride they will helicopter evac to Vancouver.

To try and get this back on track after the troll with poor reading comprehension skills decided to weigh in- Yearly besides consumables? Not so much yearly but there are things that need to be replaced. Low pressure hoses as needed. 1st stage service on your O2 and dil 1st stages (how often is...

The 1970s are calling and want their doubles back.

Anywhere but the manifold.

Sad. I was thinking a few days ago about going back.

I agree but the cost of helium makes advanced trimix OC unaffordable.

At $900 I'm going to assume that includes the hooker and blow.

No. You want to talk to as many different people and shops as possible. Sticking with one shop is not a good idea. Earlier someone suggested to get in touch with Dave Caldwell/ Heather Knowles. That is who you should be talking to.

Way, way too early. Stop taking so many courses ( well except the drysuit thing. Thats important in Mass,) Just dive more within your current training limits Look at the fish. Look at stuff. Enjoy where you are now. Revisit the tech goals in 2 years.
