Let me start this by saying The following account of my experience was in no part the fault of anyone but myself. As you read this if you take the time to you will discover every wrong move I made as I did after repeatedly going over the dive for the last couple days. There are still some holes to fill for me but here is what I remember and how it all went down.

I was to do my final two dives for my AOW on the Spiegel Grove in Key Largo 12/7. I decided to just make the 3+hour drive down, do the dives then drive back home again. I have been coming off a chest cold for the last week and woke up feeling pretty good at 4:30am. I checked all my gear again as I had the night before, grabbed something to munch on and hit the road around 6:30am. About half way there I stopped at McDonalds and grabbed a sausage mc muffin and a milk. Spent the rest of the trip drinking grape juice (I hate plain water) and enjoyed the rest of the ride. I pulled in almost 2 hours early for the 1pm trip.

After checking in and filling out all the required paperwork I decided to get my gear set up and ready to load. an hour passes and the boat is back early so we load up. The only thing we need are the two guys who decided to go to divers direct instead of show up early. Everyone loaded the boat pulls out and the Captain says its going to be sporty out there, 4-6' seas. I was excited, I like big water and had yet to dive in anything more than a foot or so. About half way out I realized I had forgotten my snack. I tried to fill the void with my fruit drink.

Once on site we were geared up in what seamed like 30 seconds flat. Here is where my trip started to go sideways. I donned my wetsuit and threw on the nice new hooded vest I had never even worn. Yeah its a little tight but not bad I said to myself. I openned my air valve and gave my regs a couple puffs each before stowing the octo in its mount. I jumped into my BCD strapped it all up and all the sudden it was my turn to get in. I slapped my fins on and headed for the swim deck, put my mask on, reg in mouth rope in hand and off we go. I hit the water signaled I was good to go and headed down the rope to the buoy.

At the buoy there was an old man 74 years of age just hangin out. he had done this dive before but was unsure this time. I hung out with him for a minute or two just to make sure he was gonna be ok. He decided to call it and went back to the boat. I emptied my BCD......um wait, I never filled it up! Interesting, I'm still floating. No big deal I told myself, I probably just forgot to put the two pounds I took out for fresh water back in. I can work with that. Face under and down the rope I practically ran with no issue or so I thought. SG7 lands you on the upper deck at 70'. I got to the deck and that's when I discovered that that two pounds was way more important than I had thought. I could not get settled down to my knees without exhaling fully and holding it out.

My normal routine as a solo diver is to thoroughly go over my gear once on the bottom and make sure it all checks out including my head. Oh, the group is taking off for the dive. Of course I was a little flustered but got over it and immediately followed the wrong instructor with another diver. Once alerted to the fact we were going the wrong direction we turned around and made a dash to the group we were supposed to be with. I was still fine but noticed I was having a hell of a time staying trim and felt like my left side was pulling down.

About 5 minutes in I started to feel the effects of Narcosis. I happen to enjoy the effect and was relishing the moment as we went down to the 90' mark. Once down I was struggling to stay down and really working hard to stay on task. This when I realized something more was going on, something insidious and just plain not right. I rose slowly back up to 80' and started to feel better but was told to come back down and follow the group. I did as I was told, big mistake. We went deeper. 100' is where things really just went way beyond wrong for me. Yes I was narcd but that was the last of my worries at this point. My face was tingling and I had started to develop a metallic taste in my mouth. This was no longer just narcd I told myself. I immediately swam up to the instructor and let him know something was not right. I wanted to go up to the 70' level and relax. No go, he told me to follow the group and stay close to him. I remember that being very troublesome for me and having to fight the urge to ascend a little as my vision was starting to fail. I do not remember from that point until we got to the flag. That is when the fog cleared a bit. I was down to 1100 PSI. Time to go up. Now you notice one thing I have been without this whole venture? My dive buddy. Never saw him until it was time to ascend. Good ol insta buddy. He went up the rope, blew through the half stop and was not at the mandatory stop when I finally got there. At the 15 foot mark I was feeling completely down on myself. I wanted to go back down and see what I missed. totally bummed, I made my way to the back of the boat and climbed aboard. I sat down and removed my gear. Oh my, I lost a weight pouch. yep 7lbs light on the right side the whole dive. I got out of my wetsuit and called my second dive. I was completely physically exhausted Which being on 32% nitrox should not have been the case. I sat for the rest of the trip and played the dive out over and over and over.

Back at shore I tipped the first mate, loaded my gear in the car and hit the road, I was famished. 3+ hours later I was home.

Now anyone with half a brain is going to spot every bad step I made through this whole mess of a dive. It turns out I was right when I felt there was more going on than Narcosis. I had a pretty good case of hypercapnia getting after me. What I felt and went through matches C02 poisoning pretty well.


All of that being said, this was a huge learning experience for me and it taught me to follow my judgment over anyone else's. I will never be rushed again. Period. As a solo diver I am very meticulous about my gear and checking it topside and bottom side. I allowed both of those checks to fall to the wayside by the rush to get everyone going. I will never again let anyone tell me I can not ascend to a level I know will clear my head. I may not have earned my AOW but I have learned some valuable lessons and feel lucky to be here to practice them. There is so much more I can say but I am going to leave it alone now and move on. If you made it to this point, thank you for taking the time to read this and I hope if nothing else you find something useful in it.

Just for sake of info. My previous two dives were to 115' with only mild narc. I attribute the above situation to the following missteps on my part. About the only thing I did right the whole trip was call the second dive.

1. Just coming off a chest cold.
2. Not fully rested.
3. Diving on an empty stomach.
4. Not following my usual gear check routine.
5. Over exerting myself at depth.
6. Using a new untested piece of gear on a non typical dive for me.

Good analysis. I'll add that solo diving with less than 50 dives, and on deep sites known for current, is not a good strategy. (Yes, I realize you had some kind of instabuddy, but it's clear from the account that you didn't talk to one another as you were getting ready to jump, didn't descend together, and didn't dive together -- that's not any kind of buddy in my book.)

I do think, to your credit, that it is difficult to gainsay an instructor when you are doing a class dive. I've been guilty of this myself. It takes "diver maturity" to be able to say, "No, I am NOT going to do that!" to someone you have hired to INSTRUCT you.
 
I would like to applaud you for recognizing what occurred and sharing it openly in this forum. I'm truly sorry you had to experience anything like this, but I'm glad to know that you have survived to dive another day. Hopefully others may learn from what you have shared with us today!
 
I want to know why the instructor did not allow you to call the dive or ascend to where you felt ok. Or thought you would. At that point the dive should have been over and everyone go to the requested depth. And if this was indeed a class it was very poorly run in that the instructor did not insist on proper buddy procedures. Sound like the whole thing was a cluster F from the get go.
 
I'd highlight #5 more than anything else. Very shallow for any serious narcosis issues, and provides an excellent lesson in just how badly CO2 can :censored: you. We all have bad days, though, and as dives go this sounds like a relatively good one to learn about things going bad.

Falling back to Stop. Breathe. Think. Breathe. Act. when something feels off is important on any dive, and the ability to keep calm only gets more important as you go deeper. Doesn't matter if it's a class or a more experienced buddy or whomever: don't let anyone rush you underwater if you're feeling flustered. Relax, ignore them, figure out the problem, calmly solve it, and then communicate with the other diver(s) what your status is (ready to continue, aborting, whatever). I'd say it's part of the independent, self-reliant mentality necessary to solo dive.
 
The instructor f'ed up just as bad as you did...and although I have no doubt the you had SOME narcosis, I don't think this was a DarkNarc, sounds more like the result of CO buildup due to overworking during the dive, which isn't abnormal considering you were 7+ lbs light, dealing with rough seas and most likely moderate current.

Put this lesson in your gear bag and learn from it. Dive safe.
 
I am curious about the fitness level of the OP?

Losing 7 lbs should not be that big of a deal at depth. Reading the account of the dive, I am unsure where the high level of exertion came into play- enough to cause a cO2 build up?


If you were getting really dizzy and feeling bad, you should have aborted the dive, not come up to 80 feet. I would be concerned that I had bad air or a bad mix or something. I don't really feel any narcosis at 100 feet, although if I work really hard, it does tend to reduce my ability to focus on a lot of different things.

Also, if you are a solo diver going to 100 feet and felt bad on what you were breathing, why didn't you switch to your redundant system and see how that felt?

I don't recall ever being so out of it, that I have forgotten considerable portions of a dive. It sounds like the OP (somehow) got himself in a very dangerous situation.

Also, if it is rough and you are diving on mooring balls and there is a current, ascending a bunch into the water column may make it harder or impossible to swim back tot he correct mooring, so I can see where the divemaster would want to keep people on the deck, sheltered from the current and in some kind of manageable configuration... Going straight up could put you on the surface, in rough water, behind the boat, so I can see where someone would be hesitant to just go up.
 
When I first cleared off at 70', I couldn't remember 3/4 of the dive. That bothered me. I asked the instructor what my behavior was like and he replied I appeared to be under control of the situation and not freaking out. So now I ask myself why I allowed him to control my destiny for a moment in time. My only answer is I trusted his experience and judgement. That will probably never happen again. This has taught me that I am the only one with me at all times.

The ista buddy was the same guy I had for my previous two dives. I had to stop him by grabbing his fin for the mandatory on both dives. I kind figured he would bug out and never really counted on him for this dive.

Dumpster, I was taking your post seriously until the last paragraph. Are you serious??? You are siding with the cattle herder when a student is signaling that he doesn't feel right and wants to ascend? I would have went up if I were the OP, and would have pulled no punches with the incompetent instructor probably before he finished climbing the ladder. That is BS, and everyone here knows it. When one member of the team thumbs it, the dive is freaking over!
