Which do you think is less dangerous at 160ft? Open-circuit air or CCR trimix?

[justinthedeeps]

People should have a look at some videos of Buford Spring a straight in and out free diving cavern that some need a CCR+trimix. Plenty on YouTube

Few of us are going to do that probably, but I think you can embed videos here using the 'media' tag if you want

what is your point anyways? your location says ireland so i assume you never plan to dive at buford but i would imagine those who frequent north florida would like it to remain open. unnecessary deaths put that at risk

My point is while I understand people love their rebreathers and want to get as much use out of them as possible ( so would I if I spent that much money) but it’s overkill in a 50m cavern. I would do the dive on a twin set of air. I’d cycle to the supermarket, I wouldn’t bring a 3ltr four wheel drive, yes I’d be safer in four wheel drive. It’s a mind set.

The trouble with cycling to the market is that it would take 4 trips to get everything home. When the market is miles away it would turn a 45 minute chore into a full day. Ice cream would melt before I get home in the summer as well.

There is also the simplicity of not owning a separate vehicle for every task. The 4-wheel drive V6 SUV may not be the perfect grocery store vehicle, nor the perfect commuter to work, but a pretty good choice for hauling the dive gear to the beach entry site. Just having a single vehicle that does it all instead of a fleet of single task vehicles.

I understand you may look on this as blasphemy, but why use a V6 SUV on the occasion that you can walk or cycle.

I don't want to spend a day making the 4 trips I would need.
I don't live within a reasonable walking distance to a store.
Weather conditions (severe heat) would make walking or cycling a dangerous activity.

You are lucky that you are close enough to a store that you can walk/cycle. Your buying habits appear to be small enough that you can carry what you buy that distance. You don't live, work, shop where I do.

I imagine most ccr divers with a decent amount of open circuit tech diving experience would agree that the ccr is not the right choice for every dive. I still think 160 on air at Buford is a poor choice tho

Yep, when multiple options are "safe enough", that decision should consider other aspects: cost, logistics (gas availability, fills for tomorrow's dives, etc.), and of course, whether any beers will be left after teardown!

I haven’t heard of a single case of someone dying at 60m or less because of narcosis.

Has Rebreather Diving Gotten Safer?

The view among many industry insiders, Pre-RF4, was that rebreather diving has gotten safer—an improvement from the estimate that CCR divers were 5-10x more likely to die than their open circuit counterparts, which was put forth at RF3 (2012). Afterall, aren’t most people doing their pre-dive...

It has been a while since I watched this, bust as an engineer, I remember disagreeing what the the conclusion from the statistics as presented.

Yeah, similar # of fatalities, but the number of divers (and therefore, # of dives) has vastly increased. Using their numbers, I'd ballpark a 30% reduction in the fatality rate on CCR.
