DIR lesson 2

[Dominic]

I'm right handed, I wind with the right - why would anybody right-handed use their left to do something? Hold left, wind right is the natural way to do it.

I have my stuff on the right because I can't see it when I'm dumping from the wing if it's on the left..

[Lou]

I'm right-handed too....surely you do the most complicated thing with your dominant hand - in this case the winding?  Seeing as I use my drysuit for bouyancy on a single & pony (which is all I dive at the moment) I never dump from the wing/BC except to start my descent, hence having it on the left wrist (where your watch goes!) seemed natural.

Oh, well, maybe I'm a mutant!

Added:
Actually, I also have to use my right hand to adjust my autodump so holding onto the reel with the left makes even more sense!

<font color='#0000FF'>You have obviously never picked up a fishing rod in anger.

Right handed fishermen hold the rod/reel in the right hand and wind with the left hand.

The other way round seems very kack handed to me.

Mark.

But that must be because casting and &quot;feeling the bite&quot; is the most comlicated actionin that case?

Well, I use my wing for buoyancy, hold my spool in my right hand, have my guage on my right arm and wind my line in using a double-ender with my left hand (and I'm right handed) I also hold a fishing rod in my right hand and wind with my left. I am not alone, or a mutant &nbsp;

Mark.

The only time I would use my left hand for holding a reel is when laying line (I would be holding my light in the same hand at the same time).

OK, here is the difference. &nbsp;We were taught that you don't use drysuit for bouyancy. &nbsp;You only put in enough air to elimnate the sqeeze so that you can still move around. &nbsp;All bouyancy is done with the wings. &nbsp;So, you need to use your left hand to dump air from your bc and see your bottom timer on your right wrist.

Also, Mike Kane stresses never using your bc inflator to dump air, all air is released using the dump valve on the lower left bottom of your wing. &nbsp;This is because you are always in a horizontal position, even while ascending or descending, so the bc inflator is never at the highest point.

I also wind with my right hand, hold reel with left. I do this both fishing and diving! My mate, who doesn't dive but would be the first DIR fisherman if such a thing ever came about winds with his left!

[Lou]

So is the dump valve on the &quot;lower left bottom&quot; on the tank side of your wing then? &nbsp;

I guess I'm veering away from DIR here, as I don't really care about how DIR does it, just on folks reasoning. &nbsp;

Most wings I looked at didn't have the dump on the tankside, which I found odd, but seemed widespread.

[Dominic]

Buddy wings do - on the left.

I'm skeptical about that really being the DIR way of doing it tho - DIR twinset wings aren't linked at the bottom, they DO trap air at the sides - if you use the bottom dump, it'll only dump the air on one side. Going slightly upright and using the central corrugated hose makes a lot more sense..

If you go to http://www.fifthd.com/classinfo/video/ascents.htm and watch, you'll see that the first thing the guy on the right does is use his corrugated hose to dump air.
He does eventually use the bum dump, but it's a bloody awkward contortion he has to do to use it - I'll stick with the hose.

I have my Vytec computer on my left wrist and my VR3 on my right wrist

I love the comment about DIR divers prefer to understand the concept of the deco an would rather not rely on a computer. Do they understand the concept of time? If so why bother using a watch. Do they understand the concept of depth? then why bother using a depth gauge.

You must understand deco before any dive to see if your within no decompresion limits or to plan your tables for the dive even if they are only bail out tables.

The computer adds a redundant brain. If the computer starts screaming at you that you are doing somthing wrong at least you can stop asses the situation and decide to folow your tables or the computer. I often ignore the computer and add my own stops in line with the planned tables but invairably the tables and the computer will be within a couple of mins at the end of the dive. If the computer said NO do another 15mins of stops when my table had cleared I would trust the computer then re check my tables on the surface. It only takes some twit to play with your lap top on a livaboard to alter all your settings and give you bum info. &nbsp;If the tables were corect I would send the computer off for repair.

On non trimix dives I will run the two computers in Nitrox mode and only have very basic geniric tables as back up. But I do have back up and thats the key. If the computers start disagreeing with one another I will revert to tables to confirm which is correct.

I prefer to understand deco and have a computer but I will never be accepted by DIR
