Ohio diver dead after diving Lake Erie shipwreck

[Jared0425]

Capt. Mike C. no longer runs the boat for a couple years now. Capt. John P. runs it now.

John is good company also. I met him too.

Tragic.

Any other news on this? Looks like he dove a Hollis Prism2.

Any other news on this? Looks like he dove a Hollis Prism2.

Searching on FB brought up a photo of his 2020 Tec 40 CCR class on a Prism.

No other news. His obit mentioned he “died doing what he loved.” The dive shop he frequented posted on FB that he died in an “unexpected accident.” Accidents are always unexpected. Some guy who said he was on the same charter was doing the usual “don’t speculate. The family is reading these posts. Info may come out in time. Under investigation.”

Boatloads of rumors, but that’s the way it always goes.

Not looking to spread rumors as wasn’t there. But do dive the Great Lakes frequently on a CCR. So would be nice to get any relevant info if something could be learned or prevent something in the future. If not, as sometimes accidents happen outside of anybody’s control, a simple “nothing new to learn here” would be helpful.

Nothing at this point. Funeral is Saturday. Autopsy was done Monday. I expect we won’t hear anything ever.

The original article I posted which was also posted on many other news sites said "According to Erie County Coroner Lyell Cook, Cullivan signaled that he was in distress to the other divers and then became unconscious."

Updated versions today like this one Ohio man dies after scuba diving in Lake Erie near North East
include...

"Cullinan signaled to the other divers that he was in distress and kept taking his mouthpiece out," Cook said. "The others went over to help him and one diver offered his mouthpiece — but by then Cullinan was unconscious. So, they brought him to the surface."

Heard second hand that it may have been a training dive…..possibly CCR normoxic trimix. Not that it has anything to do with the accident. But sounds like he was in good hands with other experienced divers nearby. Which makes it so strange…..

One possibility based on updated news report might be a caustic cocktail event. Very sad if it was one, as not much can be done underwater if severe enough.

Not familiar with the Hollis Prisim2 so don’t know how flood tolerant it is. Very sad if it was a caustic cocktail…..

Originally the Prism2 shipped with over the shoulder counterlungs, and it's pretty darn flood tolerant. On the original setup the mouth piece is plumbed into the counterlungs independent of the hoses going to the canister in the back. It's got a good work-of-breathing and is fairly flood tolerant assuming you aren't rolling around in lots of ways with a bunch of water in the loop. Getting it from the canister to the mouthpeice with some water would require rolling it into the inhale counterlung, then rolling it into the mouthpeice by going head down first maybe. The downside to the front mounted counterlungs is the chest area is pretty crowded with the counterlungs and stuff.

There is an upgrade kit to change the unit over to back mounted counterlungs. This setup moves to the conventional T part above the counter lungs and I assume would be less flood tolerant, but is similar to a lot of other CCRs.

If the canister was leaking though you might not know when the sorb starts to get wet.

I always thought CCRs could benefit from active water detection in the canister, and "fiber" optic light loops through the tank valves to detect if the valves are on or not.

It was not a training dive.
He was diving with his trimix instructor, but it wasn't part of his course. He was finished with his normoxic course.
