An age-old question: ways to 60m.

[rx7diver]

This is why when I do one of my favorite drops into 170fsw it takes nearly 5 min. Breathing good at the buoy before going under. Nice and easy down the line into the abyss. Trigger the scoot to adjust for current if needed or just a few kicks. Hit the brakes at 100, 130, 150, and 165. OK with buddy to move down or when solo verify time, depth, and air.

One more thing. Important thing: Before we began diving in the 200+ ffw range, we had made several dives in the 155 -165 ffw range over several dive outings, followed by several dives in the 180 ffw range over several dive outings. All of these dives were in the Great Lakes Huron and Superior. Some of us chose to not dive deeper than 160 ffw or so, and some chose to not dive deeper than 180 ffw or so. No shame or recrimination. (No one was pressured to do any of this.) Simply, a group of friends learning--being taught--together to do these types of dives. A couple of us went on to become tri-mix certified. Alas, I had moved away from the area (SE Michigan) by that time, and I ceased doing extended-range diving altogether shortly thereafter.

I’ll belittle people who ride motorcycles DRIVE drunk, and I’ll belittle the people who say it’s ok.

Diving deep air endangers no one other than the one breathing it. Any attempted recovery would be on a working gas and even that is only after locating via sonar.

Drunk driving often hurts and kills people other than the drunk. You insinuated an apples to orangutans correlation.

That sounds so cruel. What are you talking about here?

There is a myth that if you place a frog in boiling water it will jump out instantly because it's hot, but if you place it in cool water than then boil it, the frog will perish before noticing that it's too hot. It's an urban legend--i.e., a myth, but a useful metaphor in some contexts.

So you believe recovery dives entail no risk? Sorry, but I disagree.

“The body recovery will be done on the gas I should have been breathing anyways”

I’m really enjoying this.

I love how you changed what I wrote to fit your narrative.

Whatever you have to tell yourself to justify your irresponsibleness to yourself.

I've never said that. Don't see how you can read that into what I said. My choice to dive deep air after working into the depths and durations is my own risk. The dive itself endangers no one beyond me. Since I'm often solo my body wouldn't likely be found until it floats.

So let me reiterate, I dive in open water and don't go into places that would grab me. I'm not going into caves or sunken airplanes. You can't possibly conflate these types of dives and their risk with what I do.

My risk assessment is my own. Dive trimix, that's fantastic, I'll keep diving air until I reach the limits with which I can safely do so and want to proceed with paying exorbitant amounts to dive deeper, longer, or under greater exertion. You all get so bent out of shape when people do things under less than ideal (subjective) conditions.

There is a risk to rescuers and public safety divers. There was a car that went off the road into a river in King County. It was so sketchy one of the members of the King County sheriff's department quit after one look (source: king county deputy that's a friend of mine. He was also the first responder to the two mountain bikers who were attacked by the mountain lion). When I was a ski patroller, I would refuse to follow tracks out of bounds. There's enough signage saying you shouldn't leave the boundary and I'd rather have a retrieval occur in the summer instead of attempting a rescue and have 2 bodies to be retrieved in the spring after being buried.

Rescuers/body retrievers do die on occasion to give family closure.

If you dive air, dive solo, and don't tell anyone so that no one looks for you. I've got no issue if anyone dives air in such condition. A friend of mine in Europe has a group of friends who won't switch to trimix until 100 meters. But the group is shrinking as they slowly died off. A few years ago, 3 of them did a dive on air to 70 meters. One got separated from the other two and they found him dead on the surface.

One Facebook clown I spoke to about diving deep on air looked down upon Dr. Simon Mitchell because he wasn't diving deep daily but his Italian buddies who frequently dive deep on air are better sources for risk assessment and diving to 100 meters on air is no big deal. Yes, one of the top experts in dive medicine should be ignored and instead embrace the normalization of deviance.

Sure JYC and company were diving air on the Britannic the first time. That doesn't make it a good idea. Heck, JYC taught his oldest grandson to dive when he was 4. But what knowledge was there back then regarding the dangers to children from diving?

No, it's more like a year from now. We have to rediscuss using snorkels while scuba diving and masks on the forehead prior..

I've never had anyone question my use of a snorkel on any dive. I would feel something is missing if my snorkel is not there with me. It's only on forums that people mention it.

Good on you mate. If you are irresponsible then the following world class organisations must also be irresponsible in relation to max air diving depth:
BSAC 50 m
IANTD 57 m
TDI 55 m
IEG 56 m
RAID 56 m

USN 57-66 m
RN 50-60 m
RAN 50-60 m

In stark contrast:
GUE 30 m, although I have dived with GUE guys who have set their equivalent narcotic depth at 20 m with Trimix.
UTD 39 m
