I beat it, I did it, I got through Stress Time!

I've told my local buddies about how our Scuba Instructor here uses the last pool time of the scuba course as a sort of review of certain basic skills - mask remove/replace, reg recover (two methods), checking that your tank first-stage valve is fully open, etc. He has the students kneel in a circle on the bottom of the pool then he and the DM swim around the students, removing a mask here, removing a reg there, and watching to see the students "fix the problem". He calls this session "Stress Time".

Some of you may have seen another of my posts relating the last time I went through the Stress Time. I made it about halfway through, then on one particular drill, with both mask and reg removed, I replaced the reg and kept getting mouthfuls of water, which kicked me into a panic and I headed for the surface with the DM right beside me. "Emergency panicked ascent" was NOT one of the drills.

Well, last night's pool session started out about the same as I recalled my original last pool session - a few diver rescue drills, both "panicked diver on surface" and "unconscious diver underwater". Then we practiced turning our air on (first stage valve) then went to the deep end of the pool. The instructor said just to "play around" for a while until he got our attention and put us in the kneeling-on-the-bottom circle.

Stress Time also started out as I remembered it from last time - with the instructor and his DM starting with the basics - removing the mask and watching the students put them back on. Most of the time they didn't remove the mask completely, left it on the student's head so they could find it. Despite wearing my new low-volume mask, it still takes me two breaths to clear it - I know I have to work on it, but for the class it was all right, as long as I could clear it. Then they moved to removing regulators, and from there to removing regulators AND masks, sometimes at once, sometimes in close timing. At one point someone had just removed my mask, I had just found it and started clearing it, and they stole my reg (and tucked it behind my first stage). I abandoned clearing the mask (left it half-on) and got my reg back first, then calmly proceeded to finish clearing my mask. Just as I was getting done that my reg stopped giving me air. (and someone stole my mask again too). I reached back to turn on my air, but for some reason I spit out the reg to do so, turned on the air, recovered my reg, purged it, and started to try breathing it. Déja vu - the reg seemed to be delivering me equal portions of water and air. I tried taking low and slow breaths like I had practiced with the snorkel (to get accustomed to "breathing wet"), but it didn't seem to help. I was starting to choke when I signalled the DM "out of air" (nice big clear signal, too!). He reached forward, depressed and held the purge button, and we headed slowly to the surface.

About halfway up I had an epiphany - or as I like to say, "the light suddenly went on."

I had been inhaling through both my mouth and my nose!! Without my mask on! No wonder I was taking on water!!!

So I surfaced, nice and slow, with the DM, and started cussing a blue streak. At that point I thought I had "blown it" again. He told me, "Relax, you did just fine. Ready to go back down?"

Sweeter words were never spoken.

I went back down. This time I held my nose with my right hand to prevent me from using it, (since when I had done so before I hadn't even realized it, or felt the water gushing through). When I figured I was getting close to the bottom I reached for it with my clasped hands and came to a gentle touch down. I resumed my former position in the circle beside the diver in pink fins (thank goodness everyone wasn't wearing all black). I couldn't find my mask, but someone (instructor or DM, not sure) pointed it out to me and by sweeping the bottom I eventually found it, replaced it, and cleared it, taking only 1-1/2 breaths this time.

The DM was going around shaking everyone's hand - he shook mine too - followed by the instructor. When he got to me, he gave me another of his patented scrutinizing looks, then pointed back and forth between us - saying "you and me". Then he promptly stole my mask and reg. I recovered and replaced both, half anticipating him shutting off my air next, but instead he just put out his hand and shook mine!

I felt like laughing! If I hadn't had a reg in my mouth I would've been wearing an ear-to-ear grin (except then I definitely would've had to clear my mask again).

Outside the pool, during the debrief, the instructor told us how impressed he was with all of us, and that he would be happy to take each and every one of us to Open Water (scheduled for this weekend).

As an aside to me, he also said that he can't recall the last time he saw someone so determined!

Yahoo! I can hardly wait!!!!!

Just curious, what is the training agency of your course? ie PADI NAUI etc.

Sounds as though you had your share of challenges but you seem to have overcome them. Well done. Hope your open waters go well and that you have a long and happy "career" diving. Have fun. Stay safe.

Is it just me or is Freefloat stating that the instructor and/or divemaster shut off the student's air. I know that PADI and PDIC forbid this.

Although the instructor is also TDI certified I believe.

Yes, the instructor shut off the students' air - but not the DM nor any student, EVER, even if they wanted to do drills with each other (ie practice mask clearing, etc). As well there are certain drills (buoyant ascents being one) that hte instructor insists can only be performed when he is "within arm's length" of a student. Also any air-shutting-off is done with the utmost in control and preparation before getting to the "stress time" phase.

That's an interesting point. Far be it from me to get anyone in any kind of trouble. I'm starting to feel a little concerned about posting my story here now.

Besides the point, I feel it was very valuable if nothing else but a confidence-builder, for the student to know that he/she can reach their first stage and find their hoses and valve handles. Even Vertically Challenged students like me (short torso length doesn't BEGIN to describe me) wearing AL80s.

Freefloat,
You sound very well prepared for your open water and those stories bring back fond memories in the Queen's pool going through the same stress tests with Lloyd Shales and crew who taught through NAUI. I think Lloyd was one of the first NAUI instructors in Canada. How many of you remember Lloyd Shale's Hobby Shop where you could buy a model airplane or a set of Jetfins?

I recall our open waters were done in November during snow squalls in front of the Kingston Marine museum. All those drills which you practiced came in very handy for my first dive right off the museum in three foot vis as I swam into the guy in front of me and had my mask promptly kicked off. Other than the shock of the cold water, the memory circuits kicked in and I just cleared the mask as we learned in the pool. My air kept flowing this time though :)

Where do you do your open water dives now?

Have fun doing your open dives this weekend and welcome to the sport.

First off congratulations!!!

Don't feel concerned.......No trouble!! Every one teaches differently.
Anyone here in Kingston knows who your instructor is anyhow....
The professional dive community is small :D
I can tell by your story it gave you great confidence and your very proud of your accomplishment. That ='s a good course.

As for being "Vertically Challenged" try a AL63 my wife is small too, and she will only use 63's and being a freediver your likely very good on air, so a 63 will last you as long as most on a 80

That's why I use steel HP 80s: they are the same size as an AL 63, but have air to spare AND are always negative.

It's my firm belief that you can NEVER have "too much air". :thumb:

Well, I did air shutoff/EBA drills during my OW pool sessions (summer 2002), too - lots of them (many self-inflicted ones for practice followed by one with the instructor shutting of the valves. I can't remember if we did one in the OW portion too. These weren't "sneaky" shutoffs by any means. Then again, this wasn't PADI or PDIC - it was SSI.

Free-Float: glad to hear you will be staying down a bit longer on our future dives, now that you've seen the benefits of taking an air supply with you :D

Hmmm.... Wonder if you could wear that '63 for ballast when
sailing. Afterall, it's not like it'd contribute to drowning if /when
you did bail :)

And 40 extra pounds out on the trapeeze has to be a good
thing.

Although, on the whole air-shut-off, and surprise-mask-removals,
and all that, wow am I ever starting to feel like my training was
on the easy side.

In the log pages I had to complete for the OW course, there was a formula at the bottom that we could use to get a rough idea of our SAC rate. My best dive (the deepest! to the Aloha) had me at about 25.5 psi/min. Is that good?

I was never the student to turn any dives based on pressure. (since we were doing it as a group, whoever ran out first turned the whole dive)

My tanks were almost always turned in with 1200-1500 psi still in them.

That's the whole idea however - when was the last time you scheduled with your buddy or a perfect stranger to have him kick your mask off? Or deliberately swam too close to something and had that reg snagged right out of your mouth and hung up where you couldn't sweep for it? (I'm imagining here, I don't know if such things really do happen or not)

As pufferfish mentioned, sometimes "stuff happens". That's the reason that army recruits spend soooooooo much time on the parade square going over drill movements - after a while it gets to be so routine they can receive the command and carry it out by reflex, without thinking about it. I think that's what my instructor has been trying to accomplish with us. He talks of "building muscle memory" - he wants us to go through the motions automatically without thinking about each little detail.

He mentioned to me that sometimes if he's on a dive with his DM or safety diver (outside the classroom of course) sometimes they'll just remove their masks and swim around for a while without. For fun.

Your doing great and it will just get better! :)

I'll bet that if you use a 63 you'll feel a lot more comfortable. If you want to try one, and Adam doesn't have one available, You can try one of mine.

Just wondering:

How does someone manage 175 posts on the Scubaboard without being a scuba diver?

I also 'freedive'...... the unofficial description of freediving is "a foot on a breath" - although I much prefer 20 feet for 40 seconds or so. Long enough for some sightseeing before one has to surface. It's admittedly a COMPLETELY different experience than scuba.

Yes, Tom R is correct: you wouldn't believe how much I've learned here! (inasmuch as you can trust ANYTHING you find on the Internet) Especially when you find the same ol' arguments dredged up, cleaned off, and re-posted and re-argued. After a while you get a feel for what is common practice and what is taboo.

Stuff does happen. I've had my masked kicked a couple of times in low vis (didn't see the foot/fin coming). Had a zip tie break and the reg come out of the mouthpiece (is that why we carry an octo?). On the Connie at the 1st OFWF get together, my wife had a bubble of air in her hood and when she pushed on the top of her hood with her hand to get rid of it, her mask rode up and off (fortunately with the strap around her arm, so no searching for it). She then (it looked calmly to me, she says not) put it back on and cleared as we continued our drift along the hull.
Practice and keeping calm will sort most issues out without harm.
