[wilderydude83]

hahaha awesome.

 

[tomboyy]

ouch !!

 

[wilderydude83]

thats completely insane... glad to hear you pulled through!

Im still a new diver and was at Mammoth Lake scuba park with my dive group. The vis was pretty bad. Something like a murky 4' range. We came up to one of the sunken ship and I somehow missed seeing a nav line ran from this boat to another POI. As Im following my buddy, I notice it gets really difficult to move forward. As I realize Im somehow entangled, I attempt to get my buddy's attention but miss and she continues on. I look up and notice 2 other divers hovering about 5 feet over me exploring the boat. I attempt to signal the pair waving my arms, and pointing at my tank. They must not of realized my distress and waved and swam away. When they left and I was there, entangled in the murky water with nobody in sight I was a bit freaked lol! My thought was just to swim hard to see if I could break free and when that didn't happen, and I let the moment of panic pass, I remembered that panic does no good in those situations and I had to remain calm to think my way out of the situation. I knew I had almost a full tank of air, and was only about 25' down. As I calmed down, I was able to reach around and remove the nav line which had entangled on my tank. After that, I took a few moments to calm my breathing and see if my buddy was near. After not seeing her, I decided to surface and wait for her there.


Think it was a good lesson to learn this early in my dive career. Hopefully not something I ever have to go through again, but good to reinforce the need to stay calm and THINK.

Here's one I posted back in 2005: -


A story with a few lessons I’d like to share.

Someone commented on another thread how mischance tends to snowball and I believe this is a good example of that.

I was diving in the Philippines on a ‘fast’ drift dive at maximum depth of 34-36m. Called ‘The Canyons’, it’s a must drift-dive for anyone diving Puerto Galera and is great on Nitrox. By this time I had probably already dived it 10-15 times over the years.

My buddy for the dive was an guy in his mid-to-late forties and a good friend, and I was in my mid-twenties. He and I had buddied up a few times before, and made a good partnership. I knew he could use up his air quite fast (a bit overweight and a smoker, as I am in fact, but I’m younger&#8230, but then again, when you are aware of something you take it into consideration on a dive. For his part, he knew that I generally like to dawdle and investigate small things and was prepared to put up with me. Like I say, we were friends.

Anyway this was not intended to be a ‘dawdling’ dive, the tide was truly ripping through when we arrived by boat at the site, and you could see massive turbulence just from the surface. Our DM (an instructor & tech specialist) had dived with us 15-20 times, knew our styles and levels of competence very well. He took a look at the surface and told us that with this sort of current, there was a serious chance of becoming separated just on the descent.

We discussed it amongst the group (me, my buddy, the DM and the other guy, who was also quite an experienced diver. The conclusion was that we would go ahead with a quick swimming descent, and try as a minimum to maintain the buddy teams – any diver on his own would do the usual minute’s search before aborting. Intact buddy teams would continue with the planned dive.

Basically, we were after a fast drift and this was too good to miss as long as we accepted the basic buddy safety system – just as well we did.

To cut a long story short, my buddy & I got cut-off, but carried on with what was a spectacular dive (think Superman zooming through the Grand Canyon…well not quite, but you get the idea). All went to plan right up to the end when we had to do a blue water ascent with safety stop.

At the end of the dive, the bottom is sandy and & slopes downwards quite rapidly, you’re still being carried by the current, but now away from land into the main channel, and within minutes, you lose all points of reference.

After only a minute or two of blue water, I realized my buddy seemed a bit disorientated and was holding his gauge console and tapping it. He did not look distressed, so I swam over to him slowly and turned the gauge to face me.

We had planned to start ascent when either of us hit 70 bar / 1000 PSI, and knowing that it was likely to be him rather than me, this was what I expected to see, all I couldn’t figure out was why he hadn’t just signalled me. BTW we would have been perfectly safe waiting for 50 bar, but a little caution is a good thing.

His pressure gauge showed about 30 bar - not good, but overall we’re still in OK shape, I’m still on 95-100 bar, is what goes through my mind. For a minute, I was actually pretty happy with the situation – I had trained for emergencies and problems, and I was actually going to get a chance to put training and planning into action, a shared air ascent would be almost inevitable.

His console was one of the combined computer / pressure / compass designs, so while I’m looking at the pressure, I glanced down at the depth gauge and did a double take. We were at 53m / 175ft and sinking fast.

Not a lot of planning went into what followed immediately. I grabbed him and inflated my BC while swimming, not in order to surface, but to get to shallower water. This was not a situation I’d expected to happen.

Normally very careful about depth, how the hell could I have dropped like a stone?

The answer was twofold: -
a) nobody expected us to be carried as far as we had been by the current, certainly not as far as the down-draft that exists at the end of the ledge, so nobody had ever mentioned that it existed, and
b) We were narked. Simple as that. My buddy couldn’t figure out what his gauge was telling him, and I had got to the detached phase where I couldn’t see that any problem existed. We lost a couple of minutes that could have been fatal because we were stoned.

After the initial burst to about 20m / 66 ft his tank ran dry and he switched to my spare. At this point, I can’t remember exactly how much air I had left.

It had cost me a lot to pump into the BC, not to mention dragging my buddy up to about 35m / 120m where he seemed to click back to normal, kicking fast, and against the down draft.

We managed to maintain eye contact all the way up, not so difficult when you’re buddy is facing you and holding on to your BC’s shoulders so tight you feel they might tear! Not quite sure what our best course was, we went with my buddy’s suggestion to stay at 5m until the tank was next to empty, the ascend slowly to the surface until it actually ran out.

We must have stayed at 5m for 15 minutes or more – long enough for us both to calm down and have a look around. And to look up…

We had gone down in sunshine on a lovely blue-sky day, when we finally surfaced, it was grey, raining, we were about a kilometre from where we should have been and we couldn’t see the boat.

As the wind was already quite strong, the waves were going straight in our faces and we were kicking to stay up. There was just enough air to inflate my BC about half way before the trusty tank was finally exhausted, but we tried to use it on my buddy’s air horn to attract attention, which managed a plaintive fart that you’d not have been able to hear in church.

All told, we were actually in almost as much danger as we had been underwater, this storm was just starting to kick in, we were both tired, scared and as completely invisible to the boat as the boat was to us.

We managed to manually inflate our BC’s, so at least we could float. Taking stock, I couldn’t believe that so much could go wrong – bad weather, dive plan completely out the window, worried about DCS, no air left, no whistle, no sausage….HANG ON A MINUTE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

By pure chance, I had found a sausage on the bottom during the previous day’s dive. No-one had claimed it, so I’d stashed it in the BC pocket and it was still there! WOOHOO!!!

Using the last dregs from the tank plus a couple of breaths from both of us, we got the thing inflated and within 5-10 mins, we were on a boat with an oxygen tank taking turns, shivering and shaky, but safe and heading back to the bar for a hot chocolate with just a little brandy in it – don’t knock it ‘till you’ve tried it…

Anyway, through luck and a bit of level-headedness we both made it alright. I still dive regularly and will be taking my diving to Trimix next month. My buddy and I haven’t seen each other for a while, and I get the feeling that he doesn’t dive much anymore.

Funny thing is that I still think he’s a great buddy – one of the best I’ve dived with. What’s more is that we were together when everything seemed to go wrong and he never panicked, not for a moment. I’d dive with him again tomorrow.

Damn smokers, they scare me.

Damn smokers, they scare me.

Dude, after reading your litany of screw-ups. I'll stick to smoking.

I suggest you stick to knitting. Fancy a bet on who goes first?

 

[xjeslesx]

I've had a few of the same mistakes others have had. Forget to tighten tank strap, have it come loose mid-dive. Forgot to connect dry suit hose. Had a dry glove pop off the zip seal and completely flood my suit. Had reel line tangled around my legs (just cut it off and refilled the spool after the dive). I'm sure there were a few other foolish things in there.


The almost deadly accident was at the end of a shore dive. I had been spear fishing (hand spear), trying to make it back to shore with 2 to 3' rollers coming in. I got knocked down, the spear jammed against the bottom and nearly went into my stomach. If I had fallen on it, I would have been impailed, in surf, still with a hard exit to finish.

Needless to say I don't carry my spear in anything other that glass calm water now.

 

[seaducer]

Run out of air while shooting a zebra shark i know it was stupid it was to wards the end of the dive i just could not resist getting a few shots stung by jelly fish a few times, once really bad on the face and around the neck

Can't believe I forgot this...it just happened this past May and I am still looking at the scar every day in the mirror :shocked2:

I was in Bonaire for my now annual trip. I was seriously never cold the entire time so I was diving with only a rashguard, and that only for UV protection. My mother was on the trip this year and I talked her into a night snorkel trip. Since I was using the guard for UV, I left it in the room. Big mistake as I soon ran into a Bonairian Box Jelly, which I am ashamed to say I never knew existed.

It nailed me right on top of my left shoulder with more pain than I have ever flet in a sting before. Soon enough I started to feel cramping in my stomach and chest area but before I could signal to my mom that went away. We stayed in another 15-20 minutes until I saw another one just as the tentacles brushed up against my mask...because you know I just can't take a hint the first time.

At least that one did not sting me and all in all it was a good snorkel, and a very painful reminder that even if you try very hard not to touch anything, wildlife does not always read the same warnings we do...

BUT on the bright side, this box jelly was huge, not like the little ones that kill people in Oz, and it just hurt me a little bit. I am one of the toughest people in the World apparently:mooner:

If you are breathing from the regulator, you are removing gas from the hose. The pressure in the system will fall, unless it is replaced by gas coming out of the tank. If the valve is only partially opened, gas may leave the tank, but not at the rate at which you are breathing it -- thus the pressure in the system falls briefly and then returns to normal.

Thanks....must have misunderstood the situation. I thought valve was closed. Why would anyone ever partially open the valve?
