Smaller tanks? WHAT?! :D I'm a big tank junkie, I like the workout aspect of carrying them around. I was drooling over Duane's double 130's...they are SO not practical for me but I'm into lifting heavy things :dork2: Besides, one of these days heavy is going to cease to be fun THEN I can consider smaller tanks :D
Ber :lilbunny:

Hmmm, I'll find you a couple of Heiser 190s if I can pet your ears! :D

And I missed this to go to DM class????

A couple buddies and I contacted Duane Johnson from Precision Diving (ppo2 diver on the board) for an Intro to Tech class. I wanted to learn to dive my doubles and improve my skills, the guys are interested in pursuing technical diving. I was the experienced one in doubles with 19 dives, Steve had used my doubles once and Jim had never tried doubles and hadn’t been in the water in nearly 7 months. Duane had his work cut out for him with this crew. Duane has a complete bp/w doubles set up available for students and Jim rented that; Steve has most of his own gear and only needed to rent tanks from Duane.

Steve and I went up to Gilboa Quarry Friday night to get my favorite spot and set up camp for the weekend. Saturday morning I wander up to the bath house and a woman comes out of the ladies room and says, “There’s a MAN in there!” I asked if he was cleaning, I was just trotting in to brush my teeth and freshen up after all. She said, “No he’s using the bathroom, he said he didn’t realize it was the ladies.” She says she really has to pee and I indicate I’m going on in and there are two stalls in there, she didn’t know that. We wander in as I yell “Are you naked?” the guy is doing his business and apologizes through the curtain but says he isn’t naked…darn. She darts into the other stall and I proceed to freshen up. The poor guy is really apologetic as he comes out from behind the curtain. I tell him it’s no big deal, mistakes happen. He just has to remember he’s on our turf, I did leave out the “and if you’re not packing we’re laughing” comment. That’s how my day started, meeting new people is always fun!

Duane arrived much earlier than expected and Jim was a little late so Steve and I had Duane to ourselves for awhile. He’s a really nice guy and as Jim later pointed out he’s much younger than he looks…I mean he’s much younger than we were expecting him to be :eyebrow:. Jim arrives and we get down to business and complete the requisite paperwork.

The first part of Saturday consisted of lecture on gas management, dive planning, equipment and skills. I was rather terrified of the lecture stuff; this bunny is horrible at math and physics. I did manage to divide 500 by 2 when one of the guys was struggling with the problem. He had been whipping out answers to questions involving fractions while I was still asking if fractions were decimals but for some reason 500/2 was eluding him. I think I proved beyond the shadow of a doubt that math is not my strong point. Duane presented some really great stuff on dive planning and doing running dive plans in your head that I think anyone would enjoy learning, even newer divers. He kept things simple enough that I could follow along and that’s really saying something.

We spent some time going over gear and getting everything set up and checked for fit. I noticed the guys’ plates didn’t touch their butts while my plate was gently brushing mine. I also noticed I could lift my plate with my butt by arching my back. Duane told us we should be able to reach back and touch our plate but I wasn’t sure if that was with or without butt assistance so I asked. I could touch the plate without lifting it too but I wasn’t sure if “cheating” while fitting was going to screw something up.

The gear was fitted and we had done some propulsion technique review so it was time to head for the water. I had the orange flip fins along for this dive since it’s so much easier for me to get out of the water with them using the doubles. I get to the water and notice my power inflator isn’t connected. Steve is roasting in his 7mm and so intent on getting in the water he doesn’t hear me ask for help. Jim is donning his fins so I have him fix the problem…the problem that wasn’t there when I set up my gear….Duane…

I opted to enter with the fins in the locked position instead of repeating the “doubles with no fins” experience that happened the last time since I lack a reliable kick to lock them in place. I chose a standing backroll instead of a giant stride to keep the fins locked on entry. That didn’t work, I hit the water on my back but the right fin came unlocked. I did manage to get it locked on the second kick while holding the stair railing.

Jim, Steve and I did our version of a buddy check then Duane showed us a better way and we tried that. I’m not sure when Steve’s isolater got closed but we still managed to miss it with the pre-dive buddy check verification…is that what y’all call the “s-drill”? I’m still a little foggy on terms. I don’t remember exactly when he figured out it was closed either but he did mention it on the surface after the dive. Personally I have a hard time determining which way stuff should be turning when working behind my head…ok it’s not just when working behind my head but that makes it even more confusing than it normally is.

We were using 32% and I’m still kind of foggy on remembering the dives. I know we did propulsion and the basic 5 on the first dive but I don’t exactly remember which came first, I believe it was propulsion. Duane demonstrated a frog kick then had each of us use the kick while taking a lap around the platform as he filmed us. I ended up assigned to go first. The doubles were shifting on my back a bit and I could feel the fear of tipping over forward as I tried the kick around the platform. I was about three kicks from him when the right fin came unlocked $#%*(%(_@. I tried a flutter kick to lock it, no luck…crap I’m on video…I dropped my right hip and tried the kick lock again with my body at an angle…success! Back to the frog kick I went. I could feel the fin threatening to unlock with every stroke. It was only one fin though, the other was fine but it was seriously affecting my confidence in my kick. Overall with the tanks wobbling and my legs not cooperating combined with fear of doing a front flip and a distinct awareness of being filmed while questioning whether I would have a functional right fin I simply couldn’t relax and follow the “how to” instructions Duane had so carefully explained and beautifully demonstrated.

The modified frog kick was next; Duane again demonstrated then sent us out one at a time to perform. I get two kicks into the exercise when I realize I’m doing the exact same kick I was doing the first time…crap. Ok, so I discovered I only have one frog kick and it’s kind of a cross between a regular frog kick and a modified frog with a little flutter thrown in for good measure. The fin is still threatening to come unlocked and it’s causing me to come unglued in the focus department.

Back kick was next. I was so rattled I completely couldn’t get my legs to cooperate; it was so bad Duane turned the camera off very early in the exercise. I tried grabbing the upline as a cheater to manage my buoyancy while trying to talk myself through the mechanics of the kick; it did zero good.

Now it was time to try a helicopter kick…um yeah two legs going two different directions and I have no back kick…this is going to be ugly…and it was.

Duane didn’t film our basic 5 since that should have been pretty straightforward and it was. Remove and replace the mask, ok maybe he should have filmed it so everyone could see the extra steps required to do this exercise with ears; yes I wore the hood. The reg remove/replace/clear/retrieve was pretty standard. I like the fact that while I’m doing the retrieval of the long hose I get to put my back-up reg in my mouth while I find the primary…I like that a lot. I’m comfortable without my mask; I’m not comfortable going without my regulator for very long and I realize I need to work on that. I really enjoyed the long hose donation practice and stowing it, maybe it was just because Duane’s movements were so clean and crisp when he demonstrated it making it look uber cool.

We spent a few minutes touring, trying out our new kicks and trying to stay together as a three man team. I was pretty frustrated with our performance in that arena, it’s hard to see someone when they get behind you and I felt I constantly had to roll over to see one buddy or another. We needed to work on staying shoulder to shoulder and at the same depth though at least we were all going the same general direction. I don’t mind diving in a three man team but it’s too much task loading when you’re all trying to learn something new, practice and keep tabs on each other. I suck as a competent buddy when I’m learning because I have to focus so hard to learn new things. I prefer to be the only one training in a threesome so they can take care of each other while keeping a close eye on me leaving me free to focus on what I need to learn.

The good news was everyone came back from the dive unharmed. The rest of it needed some work and Duane used the video to show us what we needed to do to improve.

More later.....
 
Ber, I have a great recommendation for your back kick: Do a bunch of dives with a photographer. One of those photographers who sticks his head in a hole and stays there for five minutes at a time. All you have to do during that time is hang out, hover, and back kick. NW Grateful Diver was my photo buddy -- a dozen dives with him and the back kick was solid!
 
Getting quiet and focused is where I struggle the most. Once I can chill out I generally do pretty well, I have generated backward propulsion before in open water and in the pool. It may not have been a pretty back kick but whatever I was doing was sending me backward.

If your instructor isn't paying too much attention, just point your backup regulator away from you and purge until you start moving backwards :D

Seriously though, I think the best advice I heard to practice back kicking is to try to stay still and stare at a rock. Without a functional back kick, I find myself naturally moving forward and overshooting the rock despite all effort. Once you can gently back kick (I kind of have to do fractional back kicks to stay in one place), it becomes much easier.
 
Hmmm, I'll find you a couple of Heiser 190s if I can pet your ears! :D
It's a deal! We can make some extra cash on the side too. You bet unsuspecting people that little bunny can't pick those tanks up :wink:

And I missed this to go to DM class????

Sure did! We need you as a DM though so it was worth it :D A foursome would have made life a TON easier though.

Unfortunately if a photographer around here has his head in a hole for five minutes he probably needs rescued :rofl3: Hubby dives with a camera and I'm used to hanging around. We dove with Ken and Chica on a night dive at Catalina and I could stay in place...ok the time I did the best job of staying in place I discovered I was tangled in kelp but the rest of the time I could hold and be out of the way.

When we did our final dive and I led us through the trees I did go straight into the wall as we came around to the safety stop and forced myself to back away from it. I didn't go head first into the wall but I wasn't doing a very good back kick for sure.

Hmmmm, what are the jets on the sides of ships they use for docking them? :D

Ber, this was a great post. I appreciate you and Steve posting your reports about the class because it sounds like something that I would really like to consider (perhaps next year if I can not take a third trip). I would want it not because I plan to go Tech (maybe but it is not in the plan right now) but because it sounds like a great expansion on what I already know.
 
I think the biggest utility of these classes is exactly that: Expanding your knowledge, and your capabilities!

The unfortunate thing about the Intro to Tech classes is that, as far as I know, they MUST be taken in doubles (which makes sense; most people tech dive in double tanks). For the recreational diver who doesn't WANT to dive doubles, either because they don't need the extra gas or because they don't want to spend the considerable money involved in acquiring double tanks, it's hard to find a class that teaches the same kind of material. Cavern classes will do it, if you are near a place where there are caverns, but for general consumption, still the only classes I know of that teach this kind of buoyancy and trim, non-silting propulsion, gas management, basic decompression, and emergency procedures are Fundies and Essentials.

TDI's Intro to Tech does not have to be in doubles. It can be taken in a single by a recreational diver to focus on improving gas management, team awareness, buoyancy, trim and SMB deployment.

DARN! DARN! DARN! I almost had an excuse to spend the money. "But honey, I can't take the course unless I have doubles...." :rofl3:
