Holding on to a jon line can cut circulation off. Not benificial for

The bubbles business has occurred to me. But luckily I have two hands, so I
switch hands periodically. Most of the time, it is not necessary to grip
the line tightly -- I have a loop in the end I can just slip my fingers
through so the line doesn't just float out of my hand.
If or when a swell pass's over head, would it matter if your depth
changes with the swell.
It's not the swell passing over my head that I see as a problem, it's the
jerking up and down of the anchor line with the boat.
But, if you didn't, there would only be a
slightly higher degree of pressure, not directly related to just the
water overhead but around you as well. Though bouncing your O2 is NOT a
good idea, it is unlikely that a hyperoxic siezure would accure from a
quick pull to 40 fsw.
That's true, but I'd rather maintain a constant depth. After all, one of
the classic reasons for using stroke mix is in case you are too stupid to
be able to maintain neutral buoyancy at 20 feet. Wouldn't it stand to
reason that I would not want to rig my gear in such a way that maintaining
neutral buoyancy -- and a constant depth of 20 feet should be a problem.
Anyhow, if a siezure where to accure I would
rather be tied in.
Well that is a good point, however your best bet if you are trying to live
through a seizure would be to wear a full-face mask.
The only time I've had a problem with clipping in was when I dove
with five strokes whom didn't equilize their bouyancy (drysuits) and
lifted the anchor off the bottom. Everyone was pulled to the surface.
That must have been fun!
I can gaurantee you that letting go of a jon line in heavy current
is a bad thing. You can not return.
If I had to choose between letting go of the line or breaking all of my
fingers or getting smashed into the hull of the boat as it comes crashing
down while I am jerked up, I would rather let go of the jon line and then
figure out what to do. Obviously, letting go of the jon line in a heavy
current would be my last resort. In fact, I have never had to let go of the
jon line, but I would like to retain the option of doing so on an instant's
notice. Murphy applies. The day I attach the thing to myself would be the
day I needed to let go of it in a hurry.
