FFMDiver:Just started diving dry. I find that a tiny bit of air does wonders in keeping my feet above my knees. This feat was nearly impossible in a wetsuit. Do others use a small bit of air here to help with horizontal positioning? Thank you.
vodolaz:Dan has it right. As you ascend, the gas will expand and your finning will become sloppy. You'll have to go vertical to clear it out and Murphy's Law says that spot will be above the siltiest area in the cave.
Tollie:If the problem is positioning of your feet and legs I think you should work on proper positioning rather than looking to a solution that will ultimately become a source of dynamic instability for you as you move up in the water column. Why do you have problems with foot and leg placement does it affect your trim? With legs out your trim may be thrown off. Where do you carry your weight on a belt and BP or just a belt how about trim weights on the BP? How about the position of your tank on your back to far down your back. How about more land drills to get the leg positioning spot on?
At any rate work on the fundamentals and dont look to a work around.
