Subject: RE:Lift Bag Deployment
Eric

Lift bag deployment is a very basic skill that will be different in all
areas of diving.  I am assuming that when you are reffering to lift bag
deployment you are reffering to using it as a stafey of decompression stop
platform.

I wont deal with specifics of lift bag deployment other than what you wrote
in your original email because knowing this list, well you understand....

When it comes to running out line before you deploy the bag will really need
a clear water environment.  In Canada we use lift bags on every  dive for
everything from a decompression platfrom to let the surface support know
were we are in decompression. One of our problems is that we are in current
and minimal visibility.  If you allow 50 feet of line to drop below you,
that means you will have 40 feet of line that you cant see where it is going
or what it's doing, you only have to be ten feet off the bottom not to see
it... When you choose the lift bag system that you want to use, make sure it
applies directly to your local area conditions ie: visibility, current and
of course, is it really needed ect....

If you want give me an email at rcreight@di*.ca* and I can send you some
more articles and information on lift bags and deployment techniques.
