Steve-

Thanks for the complements on the website, I appreciate it. You need to =
read it a  bit more carefully, however, as the answers to your questions =
are contained within the web site.

I am also concerned at your self-imposed 150' air limit, I think that an =
EAD of 100 is a bit more appropriate. From the general tone of your post I =
think that perhaps you may need a few more dives under your belt and =
perhaps some training and/or tutelage on the practice of Deco diving.

You don't really "learn" helium, all He does is make your dive safer. What =
you really need to be very good at before you do serious Deco diving is =
gas management, Deco bottle preparation and utilization. You really need =
to be perfectly comfortable under water in all conditions and not have any =
tendencies to stress out when problem arise, and indeed problems *will* =
arise sooner or later.

You also need to make sure your gear is squared away, no stupid bullshit =
like OMS stuporwings, steel stages, suicide clips, convoluted hose routing =
etc. Use DIR guidelines (www.gue.com) and don't listen to the "old school" =
techdivers, there are currently better ways to do things which are make =
techdiving more survivable, particularly to the newbie.

Then dive your gear. Dive rec profiles with full doubles and stages and =
practice, practice, practice. Helium is your friend, Oxygen is the thing =
to worry about, it's the O2 that will kill you.

On the tables, it is insane to think that you can do gradient calculations =
in your head, as one rocket scientist claimed he could do. After you do a =
whole bunch of dives using a tables calculation program you begin to see =
trends on how your particular Deco profile shapes up.

Deco is not an exact science by any stretch of the imagination. A Deco =
program takes mathematical theories, various fudge factors and applies =
them to all physiological types in all underwater situations. Wish things =
were that simple.

Every individual is damaging his or her body to a certain extent when Deco =
diving. You try to manage the damage, and the body repairs itself quite =
well in most cases. As it is your body only you can tell when your profile =
is not quite right and you need adjust appropriately. And you gain this =
knowledge through experience and research. It is your ass.

So go back to the drawing board, Steve, and read my website, the books I =
mention, Techdiver archives and anything else you can get your hands on =
concerning Deco theory and practice, practice, practice.
