One dead, one missing (since found), 300 foot dive - Lake Michigan

[broncobowsher]

The thing is, there is of course a higher incident rate with CCR than with OC, that's pretty easy math to do. What is hard to do is to say for any GIVEN dive if the risk is higher with CCR than with OC.

The reason why that's hard is that it's not clear how you would compare cohorts of OC and CCR dives, and see if the injury or fatality rate is higher with CCR for a cohort that is matched for profile. Since the average CCR diver is doing bigger dives than the average OC diver, you can't just compare the raw numbers.

Going forward, it's gong to be harder and harder to do that analysis, since fewer and fewer people doing VERY big dives are doing them on OC at all. So if you tell me that there was an accident on a 300 FSW dive in 2019, I'm also going to assume that it's a rebreather, but mainly because so many more people doing those dives are doing them on CCR. At some point, the amount of gas you need to carry with you becomes prohibitive.

I do agree with you about the need for surface support for "recreational" dives of this magnitude.

Along these same lines, what percentage of 300' dives are on OC compared to CC these days? Add in some filters for training dives and remove the commercial/military.

I recently scrubbed a 200' dive due to lack of surface support.

no

"no" what?

The wife’s rebreather is not available to be examined. Chris apparently has some info on the incident.

Exactly and I literally GROAN every time someone inevitably says "was it a rebreather"... it's exactly as productive as reading a thread about a 250kph motorbike crash and asking if it was a 1000cc sports bike, before telling everyone how much more dangerous those things are than scooters.

I would pick my Fireblade over ANY scooter at 250kph. At nearly 100m - the limit of OC Advanced Trimix - this was a 250kph dive.

Wouldn't it be nice if his response wasn't so obscure.

I just hope if they had children they will be ok. I can’t imagine how kids would deal with losing both parents so suddenly.

Very very sad situation.

wouldn't it be nice if there was reading comprehension? I posted the units weren't found to be examined, someone posted they assumed the unit of Sue was as she was recovered, I posted no.

Simple, sorry you found it obscure, it was neither uncertain nor hidden as far as a reply goes. It was direct.

I heard from someone familiar with the couple and the dive operator that they had 6 children some of them still teenagers. I've not independently verified that as I don't personally know either diver. If true, this accident is that much more tragic and horribly sad.

Very sad!
My condolences.
