After seeing how the post I wrote about the reverse block resonated with people, I would like to make another post today, namely about the most frightening moments I've ever had.

It's easy, particularly for novice divers, to think that people like myself, with decades of experience, thousands of dives and a deck of c-cards have everything under control and nothing bad ever happens.

I wrote about the reverse block because of that. I wanted to show that I am still human and I can still make mistakes. On the internet there is a strong tendency for (technical) divers and instructors with a lot of experience to project an image of themselves as always solving problems correctly, always making the best decisions, and in the case of instructors in particular, having a monopoly on good ideas that lead to perfect students diving perfectly.

None of that, of course, reflects reality at all.

So I will start. I urge experienced divers to share their own stories.

-------
First
-------
1985. I was certified as AOW and we were making a deep dive along a wall. The bottom, for all intents and purposes, at the bottom of the wall was unsurvivable. A diver who diving with a group slightly ahead of us got caught in a large ball of discarded fishing line that he didn't see. He started sinking. The incident started at 42 meters. My buddy and I had just started our dive and we saw this happening. Nobody in his group did. We went after him. This was the first time I had dived deeper than 42 meters. I couldn't tell how deep we were when we caught him because the (analogue) depth gauge I was using was pinned at its maximum depth. This was also my first deco dive or at least my first dive where I was "off the tables" and unable to to know how to ascend. I was, at that time, unaware of oxygen toxicity, gas management and ascent protocols. We returned (at a rapid pace) to 30ft. (10m) and waited there until our tanks were empty on the assumption that any damage done by our deep incursion would be fixed by that. Upon surfacing we didn't know if we were going to get the bends or not. I was, frankly, scared. It still gives me the heebiejeebies to think about this incident more than 30 years later. We did something there that was completely out of control (also the rescue) and we got off easy.

Second

2002, I think. I was working as a DM. We temporarily lost a diver during a dive. The situation was that we were on a platform at 25m and doing some exercises for the AOW (deep) dive. A group of divers (maybe 6) descending LANDED on us and kicked up so much silt in their attempts to slow down before impacting the bottom that the visibility went from 5m to black-out in a matter of seconds. I grabbed the two divers right in front of me and dragged them out of the silt cloud. One of them turned out to be our diver and the other one turned out to be one of the idiots who landed on us. We were missing a diver. We surfaced. Naturally our divers were told to surface if they became separated but this diver did not. He remained where he was and waited to be rescued. On the surface we decided that I would search for the missing diver because I had the most experience of everyone (including the instructor). At that point I was a DM but I was already technically trained. I had very limited time. I went back down and eventually found him but it was luck. He survived and my beard got grayer overnight. If I couldn't have found him in the next 5 min his death would have been on my conscience until I died. This was so frightening to me that I nearly abandoned all plans I had to become an instructor.

-----------
Third
-----------
The accident. My team saved the life of a diver who ran out of air during an AOW training dive (by another group, not mine) and was left for dead on the bottom at 18m. We acted quickly and professionally and got him into the hands of paramedics within about 10 min. As an aside, the fact that the Dutch paramedics were able to be on scene so quickly was no small part of this! He looked dead when we retrieved him. He lay in coma for several weeks after the incident. Doctors had basically written him off when -- unexpectedly to all -- he woke up and subsequently made a reasonable (albeit not full) recovery.

The impact on myself and on the members of my team was substantial, particularly because of what we viewed as our 'mistakes'. One diver (the DM) stopped diving. He started hyperventilating during the descent to find the "body" and after that he started to hyperventilate on EVERY dive. He stopped diving.

To me it changed EVERYTHING about how I view training and my role as an instructor. I didn't organize things on the surface as well as I could have, if I had had a second run at it. Yes, I had the EMS on site in 10 min. Police, paramedics, trauma doctor, helicopter, fire department with a boat, a private boat.... all of that I had..... but I was overwhelmed and not communicating as well as I could.

Someone tried to chase my (uncertified) OW students into the water to go search. He didn't know that they were uncertified and I ripped him a new one in a way that I regret, giving in to the emotion. An NOB (CMAS) instructor showed me by example how to control the dive site in a way I had never learned, I missed seeing a diver (the DM who caused the accident) displaying passive panic. It only became apparent to me when they had to take him away by ambulance when he collapsed.... it was MUCH more messy scene than I had ever imagined and I was not in control as well as I would expect from myself. At one point, once the EMS had control of the surface situation I grabbed another diver (a DM) and went searching myself. This was a mistake. I can't get over the mind set that drove me to ACT when I SHOULD have been coordinating! I'm like the guy who charges into a burning building because I can't fight the urge to DO SOMETHING! I HATE that about myself.

Since that time (it's been years) I've been replaying that event in my mind and thinking, "if I had only done XXXX then YYYY". It drives me CRAZY to think that if we were sharper we could have found him 30 seconds or a minute earlier and his recovery could have been better. The fact that he survived is utterly astounding. These things never end like that.... but I feel responsible for the fact that it took so long.

This was a formative moment in my diving. I considered stopping as well but eventually decided not not to. To this day I cannot -- and will not -- teach or participate in the Rescue course, even though I may be the one instructor in my circle who is most qualified to talk about the differences between theory and practice. It's just too intimidating.

Some of those OW classes with everyone bunched up and people "Swimming with their arms", it is not that unusual to see a regulator hose get caught and the reg ripped out, and most of the time, the offender has no clue they were even involved. LOL
Mask kicked off, with same, that the offender had no idea
 
Experienced my first "incident" yesterday. I was quite pleased with how I handled it, and I did another dive an hour later, but it's been on my mind all day today.
I went diving with an inexperienced instabuddy. We planned a shore dive to a wreck I'm familiar with, swim around it a bit and come back. The base of the wreck is nearly 40 meters down but the interesting parts are at around 25 and that's what we were planning to look at.
Before we even got to the wreck, I realized that my buddy was swimming way deeper than he should have been. I tried to get his attention and failed. After a minute I swam down to his depth and tapped his leg to get his attention and made him ascend a little - he was at 35 meters at that point. We ascended together to 27 and swam a little further, and I realized he had once again sunk without noticing. I gestured him upwards again - this time he noticed - and he ascended a little. Then all of a sudden he started swimming in circles in a superman pose.
Oh sh*t, I thought, he's narced.
(As a side note, I genuinely don't know if I was narced too - I've never gone below 30 meters before. All I felt was a little dizzy, but that's all I feel when I drink, too.)
I grabbed his arms and got him to stop spinning. I pulled him upwards to 25 meters, slowly. Then he tried to keep ascending way too fast - I think he thought I was trying to do a CESA, inasmuch as he was thinking at all. I stopped him and held him at that depth for about three minutes, just breathing. Then I signalled to ask if he was ok and he said he was. I asked about his air and he was on 100 bar, which was just under our planned turn pressure. We hadn't even made it to the wreck but I guess that's what happens when you go that deep. So we turned and headed back to shore.
As we neared shore he tried to ascend without a safety stop. At this point I admit I thought he was kind of an idiot and forgot so I just signalled safety stop, emphatically, two or three times. Then he remembered to tell me he was low on air. I don't know how he used his air so fast. So I shared air with him, the first time I've ever done that outside drills. I know safety stops are technically skippable in rec diving, but after we went deeper than we should have I didn't think it was a good idea. I had enough air, anyways.

So, all in all: losing buddy roulette like that was frustrating and scary. At my level of experience, ~50 dives, it's good to discover that I can put theory into practice. It's also kind of startling to see the difference between his ~25 dives and my ~50; I wasn't much better when I was at his experience level (though I only did guided dives). And it's weird that I'm more scared today of what almost happened than I was yesterday.

Good thing one of you kept your head about you. Good job. :)

Did you do a recap with your new buddy? 🤔 It would be interesting to see what your buddy thought was happening.

I did. I had to explain the difference between nitrogen narcosis and the bends, which is worrying. He was confused and disoriented about the whole thing - he didn't seem to remember the spinning in circles part. He said he was looking for me, but that doesn't fit with his behavior. He was just really blasè about the LOA and too-fast ascent.
I tried to convince him that he should do some guided dives with a DM but he didn't want to because those dives are usually shallower which apparently is bad. I then told him that he needs to rent a wrist computer so he can watch his depth the whole time, and he agreed.
Maybe I should have been harder on him, but I'm just some rando who did one dive with him, how much influence do I really have?
 
It's too bad that he couldn't turn out to be a buddy fot you. Perhaps some day but it does seem that now is not the time.

He was making a shore dive to 25m (planned depth) without a computer? That would have been a huge red flag. I can seen not having a DC and doing a shore dive with a hard bottom at, say, 15 or 20m, but that he could get down to 30 or 40m without a measure of time, depth or deco is pretty scary.

He had a computer, but the very basic kind that's integrated with the depth gage and air gage. He was going to rely on my computer for NDL limits and add extra surface time for safety. In retrospect, you're right, that's a red flag and I should have noticed in advance.

Even a basic DC will provide the user with NDL. He shouldn’t have needed to rely on your computer. Perhaps he was using a rental computer and had no idea how to use it.
 
Man, those are some seriously frightening moments! I got chills reading about the diver caught in the fishing line at 42m. Thanks for sharing your experiences and being so open about the mistakes made - it's a great learning opportunity for all of us. The fact that you saved multiple lives despite the chaos just shows how skilled and level-headed you are under pressure. I can understand beating yourself up over the "what ifs", but try to focus on the positives - you prevented multiple deaths through quick action. That's incredible.
