Horizontal Obsession

[Blackwood]

In addition, the horizontal trim provides vertical drag, helping divers maintain a constant depth."

That's wrong.

If you are creating vertical drag, you are not maintaining a constant depth.

probably my english is poor....

IT'S A QUOTE OF A MANUAL.

by the way I think it means you are less hydrodynamic in vertical shift and so it helps....
but that's not the core of my post...

wait,
7 pages of replays and none says "Hey man what are you talking about?"

If I am descending I swim mostly vertical head down.
beeeeep.
wrong 1. in that position your bood flow go to increase pressure in your head, so' it's bad for ears equalization and dangerous.
wrong 2. why you swim? you consume more air. deflate the jaket and be horizontal, don't move.

If I am ascending I swim mostly vertical head up.
beeep
wrong 1. why the **** you swim vertical? deflate the jaket and just some kiks in diagonal. use your breathing to correct your bojancy.
wrong 2 if you are vertical you have a difference of pressure on your body, about 0.2 bar from your head to your feet, no good in hard diving

If I am swimming horizontal to the bottom I swim horizontally.
OK, 1 right

If I need to look up I assume a position that allows me to do it comfortably.
yes horizontal with your neck torwards back.

Always horizontal is for dead people.
Talking without knowing is for idiots.

"The horizontal position is often called prone, superman, or skydiver position. For a scuba diver, the horizontal trim is the most efficient way to move through the water. In addition, the horizontal trim provides vertical drag, helping divers maintain a constant depth."

See what I mean.

I'm not sure I do see what you mean or what the intent of your post is... the above reply is right on the money and he says it very eloquently and without derision.

Perhaps you just don't want to hear the truth about your diving skills and approach?

Don't worry too much about your english... I could understand your post (though the last bit was clearly a quote from something ).

I'm just being picky. If you are maintaining position vertically, there is no drag in the vertical direction.

My horizontal trim, no BC or other help needed.

sorry, but definetly:
bad trim (fins are too low)
bad technique (in a cave use frog kiks!)
bad equipment (if you know someting about phisics you know the the double corrugate is ****)

by the way, now you are my personal myth ;-)
I will go on a hunters forum to sustain vegetarian rights!

Seems ironic doesn't it.

I am swimming into a large rocky cavern with no chance of silting so the type of kick is irrelevant.
I know physics, on the other hand you do not know double hose regulators to make such a statement.

wrong - Head first descents are not dangerous. Head first descents are not recommended for beginners because they may descend faster than they can equalize, but for experiended divers who have no trouble equalizing, they are fine.

Maybe he uses less air than you and can afford to waste a pint or two. It's his air, it's his choice.

beeeeep.
wrong - His buoyancy doesn't need correcting.

The pressure difference between head and feet in a vertical ascent is irrelevent. That dog won't hunt.

If I need to look up I assume a position that allows me to do it comfortably.
yes horizontal with your neck torwards back.

beeeeep.
wrong - That's fine for you, but you have no idea what is comfortable for other people.

Always horizontal is for dead people.

We are all guilty of talking without knowing from time, but we aren't all idiots. I'm sure you are not an idiot, but here you are talking about things you do not understand.

"The horizontal position is often called prone, superman, or skydiver position. For a scuba diver, the horizontal trim is the most efficient way to move through the water. In addition, the horizontal trim provides vertical drag, helping divers maintain a constant depth."

Horizontal is the most efficient way to move through the water horizontally. It is not the most efficient way to move through the water in other directions. If you need vertical drag to slow an out of control ascent or descent, you have a bigger problem than trim.

bad trim (fins are too low)
bad technique (in a cave use frog kiks!)
bad equipment (if you know someting about phisics you know the the double corrugate is ****)

beeeeep.
wrong - His trim is fine. A frog kick is often the correct kick in a cave, but not always. Double hose regulators are excellent equipment. No comment about not using a BC?
