Rob, are you talking about shooting a bag?

Nope. Easier. Think teamwork and guess again.

And think back to the A-B-C-D's of managing task loading. Keeping your depth without a reference *is* a task. Don't treat it like it isn't. How would you deal with that if you had to fit it in your A-B-C-D's?

Mike, I didn't mean to imply that instrument flying and instrument diving are identical --they are not (and for some of the reasons you said). But I do believe the techniques taught in instrument flying are what is needed for "instrument diving" -- that is, not fixating on one thing (task, instrument, etc.) and letting your mind absorb the information from all of the various sources while still doing some other task.

Question regarding not having an "attitude" indicator while diving -- my compass (Suunto) IS an attitude indicator to some extent in that if it is level it is an "artificial horizon" and if it is not level, I can tell. And of course we always have our bubbles to tell us where "up" is (unlike sitting in a plane -- at least I hope you don't have bubbles!).

I agree and if I don't have to read I can use hunter eyes...not focusing on anything specific. For instance, You can do a fine job of shooting a bag or clipping off a bottle whout ever taking your "gaze" off your surroundings.
 
Regarding the sampling rate of depth gauges- I don' think it's too relevant. Even if there is a lag, you can still compensate for it, you just have to correlate your depth and breathing cycle so that you don't overcompensate. You might notice you are 1' too high, then exhale, do part of your task, then check the gauge again. If you are still high, then you are probably positively buoyant. If you are at target or slightly below it, you're probably fine. Think of it like riding a see-saw or teeter-totter and make sure you are breathing in on the way down and exhaling on the way up. A little flucuation is fine, as long as you are in control overall. If you are trying for 20', and your gauge is bouncing around between 22' and 18' it's fine, you can fine tune your depth with the floaties. If it's 20' one minute and you exhale and it's 18', that's probably not going to work.

At YOUR age?



Well.... that part I can believe..... :D

It's nice to see you too Rob. 39 is not old.
 
That's what I thought until I turned 40 and the mid-life crisis grabbed me by the throat and squeezed until I had hunter-eyes and couldn't focus on anything specific.

LOL (nice to see you too...) :)

P.S. I get what you're talking about. I think it's the same message I'm trying to give to Lynne. She's signed off now and I have to go to bed so I'll lift the curtain a bit so she doesn't spend all weekend wondering what I'm on about.....

The "hunter eyes" is sort of the key. It's splitting your attention between two tasks. On the one hand, you're performing the steps of launching your blob and on the other hand you're watching your buddy.

You're going to say "yeah but the horizontal/vertical thing and watching Kirk only works during the day".....

No.

That means that you and Kirk need to talk. If you're performing a task and Kirk has the "task" of watching depth then his job is give you the visual cues you need to keep your depth. I needed to let it sink in what you meant about horizontal/vertical separation but now that I can visualize it then I realize that Kirk is watching YOU!

<raspberry>

He should be watching depth and orientation and giving you the cues you need. If *he* is anchored in the water like the unmovable object he should be emulating then all you need for visual reference is to keep an eye on the edge of his mask out of the corner of your eye.

Either you're not really *looking* at him or he's watching you and moving around when he should be showing you what "still" looks like.

For Mike that's second nature and he's calling it "hunter eyes".... watching for slight movement without focusing on anything specific. In your case, Lynne, I know that you get a little dizzy in the dark so I'd suggest looking at the contours of the mask (clear straight lines).... but you have to tell your buddy to remain *absolutely still* even if you don't.... that's the part you're missing. Maybe he even needs to shine his light on himself instead of on you while you're busy.

That's part one. Part two is that you're seeing bouancy control as a given but it isn't. In zero reference situations it's a task. Treat it like that. Spend time on it. Slow down the execution of other tasks so you have the time to look at your buddy, so you can adjust your buoyancy (A-B-C-D). You're busy with D (launch the blob) when you haven't go your B's in a line (buoyancy control). Switch back and forth. Unclip the blob....check bouancy.... unfold it....check buoyancy...get it aligned in front of you ...check buoyancy...bring it up...check buoyancy...breathe into it ...check buoyancy... and so on....

That's the A-B-C-D's.... get coordinated and don't be afraid to take a couple of minutes to launch your blob. Doing things too quickly will bite you every time....

That's a start.... does it make any sense?

I said 39 isn't old. I didn't say that I'm 39.

I'd sure like to figure out how to know where I am without something to look at, though. Maybe it's not possible.

It's possible only in the sense of knowing your position before the task and knowing that your buoyancy is solid and therefore shouldn't change while you are doing the task.

Once you move and lose all visual reference points you can't figure it out without instruments or reference points. That much we can learn from flying.
 
This might be the ideal situation where a heads up display like the Oceanic one will prove it's worth. With the procedures discussed in this thread of rotating through tasks coming back through and checking gauges, having the gauges always visible may make it easier. It brings in the flight corollary as well, as that is the solution they have for the heavy task loading of combat pilots.
