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.

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.

Story number two, and I expect to get flamed for this. My buddy and I were diving a very remote cave. We had planned this for weeks, even had a member of the local caving club, (not diving) who were interested in what we might find in there had taken the time to clear the bush and make the road passable for my truck to get near the entrance. The cave entrance looks like a mud puddle with a creek spilling out of it and I didn't think there was room to get in. My buddy puts on his drysuit and grabs a 40cuft bottle under his arm and goes for a quick look. Five minutes later he come out shouting, "that thing goes!". So we suit up and head in. Aaron goes first laying line from an exploration reel as he proceeds. At one point the cave floor goes up and around a giant column and Aaron had decided to go on the high (far) side of the column rather than what I felt was the easier passage being the low side. He made it through the restricted passage around the column and signalled for me to follow. I started in and soon got stuck. There is no worse feeling than being stuck in a head down position in my books. I tried to wiggle and shift to different angles but could not make it through. I signalled to Aaron that I couldn't get through and to go ahead without me. So away he went and I started back feeling a little ashamed of myself. About that time I thought I will have another go at it so I tried again and after a couple of minutes got through feet first. Now I'm swimming like crazy to catch up with Aaron. After about 20 minutes and no Aaron in sight I get to an even worst restriction and knew I would never get through. I head back knowing Aaron was not expecting to see me although I did consider leaving a note on his line. As I got back to the column I decide I would leave the line for short time in order to take the high side which I was convinced was bigger passage. Well it wasn't I got royally stuck. My arms above my head not able to touch anything, my hips and rebreather forming the perfect wedge. I started to feel panic coming on but gained control, telling myself I have about 6 hrs worth of oxygen likely more if I relax and Aaron will see me when he comes back anyway. It was a long 6-7 minutes before I felt a tug on my fin. He quickly assessed the situation and was able to pull me out.
This incident had an impact on me and I knew if I did not go back and dive that cave again I would never forgive myself. My next dive went much better and I discovered the trick to getting through that first restriction although I never did get past the further restriction I at least felt good about overcoming the fear of getting stuck in a cave.
I think it is very valuable to read about such incidents from the standpoint of the diver in trouble. What do you feel you erred on, other than the result of getting helplessly stuck with no buddy in sight? That is very clearly not a desirable place to be. No flamming - any incidents that one can walk away from are learning opportunities.

Failure to follow guideline. What I did was essentially a visual jump. Although that didn't cause me to get stuck per se if I had silted out the cave while struggling to free myself my buddy may have not seen me and exited the cave, wondering where I had got to.
 
I'll add my scariest self inflicted moment. (buddies and others in the water gave me a different kind of scare occasionally)

A few words of synopsis: Inadequate planning, lack of training, unexpected conditions and poor decisions making all added up to a bad situation I placed myself in. In hind sight: pivotal moment in my diving where I began dedicating funds to quality specialized instruction. It was when I realized being comfortable underwater and having good mentors in one environment doesn't translate to safely diving in unfamiliar situations. Being experienced underwater doesn't mean trained for all conditions.

First off, it's years ago and my worst experience in untrained cave diving.

Discovered an unlined passage of a cave, belly bottles / slung tanks tight passage. Had a ball of string with me. Laid it until I ran out of line. Decided to continue exploring a passage a little further. No obvious side chambers or forks.

Or so I thought.

I reach my 1/2 and turn the dive heading back out. To my horror I didn't realize the ceiling was heavily silting as result of my bubbles (and probably sloppy finning) and I was in less than 1ft viz. (Couldn't see my hand at 1/2 arms length.) No line. I'm now feeling my way along the wall by memory. Expecting a turn in the passage.

Not feeling it.

I continue to a dead end. Now retrace in 0 viz. Find the passage which was lower than I remembered. Viz improves. Enough particulate in the water to reassure me I'm retracing my path. Narrow section. Tanks off, continue to wiggle.

Jammed. Wedged in a restriction that I didn't remember being so tight. Continue. Stuck worse. Realize I've jammed myself into a dead end. Back out eventually.

Air a concern.

Discover another narrow passage. Looks familiar. Wiggle through. Back on track. Continue to my line.

Pull my line as I go. Bad co2 headache from forced conservative breathing expecting to run out of air before the exit. (dead calm and iron will counting to maintain a slow full breathing pattern that stretches each breath)

Exit uneventfully, continued swimming subsurface in open water. 14 breaths later the reg breathed heavy and I was out of air. Marveled at why I bothered to waste time removing the line as I went.

I hope the take away lessons learned are obvious. Any questions welcome. I realize I was nearly a statistic.

Humbly,
Cameron

P.s. My other significant scare was buddy separation (3ft viz) from a special needs diver who needed assistance. I found him unharmed. But it was horrifying for the 2-3 minutes it was ongoing.
 
“Exited uneventfully” right

You sir have something inside you that is of great value. You think well under stress and don’t panic. That’s pretty important stuff. Add caution and knowledge and it’s even better.

I’m glad you are still with us. Thanks for the story.
 
This is exactly why I will not go dive with another DM until I feel confident to make these kinds of decisions on my own. As you can see by my number of dives, I am new to diving but I have people I trust around me. All my dives have been with the same DI who knows me, my skills and my history. I want to go dive other places but if I ever end up diving with a DM like the one in your story, I want to know enough to make decisions. I know it will be a while before I get there though.

So I have my own story - not anywhere near as scary as yours - and some on this board may laugh at my silly newbie experience. But it was my first real lesson in safety.

I was on my 4th dive for my OW. I was the only person in the group who wasn't at least AOW. That was my husband. Everybody else on the boat was rescue, DM or DI. My husband and I were the only ones on the boat with less than hundreds of dives - a very seasoned group who all had their eyes on us.

My husband/buddy was having problems with his regs during the dive - occasional wet breath. He wasn't phased by it. Towards the end of the dive, we were at about 20 feet just coming up for our safety stop when his regs started failing intermittently. He was only a few feet from me and I pointed to my octo. He reached for it and tried to pull it towards him but couldn't.

There is this thing some people/dive ops do where they bend the octo hose and put it in a D ring on a BC. I'm not fond of the practice but there was no keeper on my rental BC so that's the way I set up my gear. The group descended to the sandy patch, and as people started to swim away for our dive, my husband approached me and gave me a carabiner as a tank banger - at a point when nobody else in the group could possibly have noticed. I clipped it in the first spot I found. Turns out it was in the loop in the octo hose. This is why my husband couldn't grab it later when his regs were failing. He ended up doing a CESA and was fine.

But I have huge guilt about that. Should I have know better than to clip it where I did? Should my husband have know better than to give a newbie a carabiner? We talk about this a lot. Our last dive trip (my second) didn't give us the opportunity to buddy - he got sick and we had only one dive together. But this next trip, we will be working with our DI on things like buddy breathing (I'm better on air than he is :wink: ) and other things we should be able to do as buddies. I am also doing my AOW on our next trip.

I would appreciate any advice from you and the other seasoned divers on this board about things we should be working on together on our next trip.

What I have done since that dive (lessons learned)
- bought a dozen octo keepers to make sure I will have a supply just in case the one on my BC is missing
- realized that underwater is not the best place to add something to my gear
- bought my own BC so I will be super familiar with it
- bought my husband his own regs :wink: mostly because he will never trust rental regs again


Has your husband tried to use his own octopus? I once got a "wet" second stage - due to misfolded exhaust diafragm - and went on to use my own octopus without any problem .

For me, that was drummed into me as the first thing to try. I fluffed reg recovery during my first OW dive (I was turning too much and it was following therefore hiding itself from me). Instructor said simply "why didn't you just switch to the octo? It was right there in front of you." I had the proverbial lightbulb moment.

Dropped primary - do one sweep, if that fails, switch to octo and work the problem.
Issue breathing on primary, switch to octo and work through the problem.

Only if my octo fails as well (such as OOG or first stage failure) should I end up going for my buddies octo.
 
Interesting that I rarely heard an instructor mention using the octo if a sweep to get the primary fails.
 
When I'm at 1000 psi that quickly goes down to 700 while I'm still at 70ft. I still made my safety stop and got out just fine tho. But scary, that last little bit will go fast. Never again will I do that.

Also, I was in a drift diving trip to go see some wrecks for my advanced open water. The dive site is pretty close to the shore... So you have to gear up on the way out. And since it's a drift dive, and you just jump right in without sitting on the surface then going down.. Well when I got down there I realized my pressure inflator hose wasn't connected!!!! There want enough time to gear up on the boat. My dive instructor hooked it up for me down there at the wreck. And the current was STRONG. Just imagine if it was time to surface and I wouldn't have been able to because it wasn't connected! The next day I geared up BEFORE the boat left. And it was a much smoother trip. Because when you get out there they will rush you off that boat (because it's a drift dive and you'll get left if you don't jump in with your group /buddy). And actually there was no current until we hit 55ft. You're just dropping down and all of a sudden you get pushed so fast you'll even miss the wreck. Boy can those tiny fish swim against the current though!!!!
 
there is no need for a safety stop if you believe that you will be OOA. FYI, 700 PSI goes a long way (15/20 minutes) @ 10 feet with an average SAC rate.

But there is an obvious need for a buddy check before every single dive. :cheers:
