As has been stated, why is a Al tank better for staging when it floats
when it is empty, but back mounts should be negative when empty?
Did I miss a post? What is the big deal?
When I wreck dive, the stage/travel tanks is on me all the time as are
my back mounts. If I take floaters on my back and as deco, I'm
floating at the end and need weight. If I take all steels, I'm putting
extra gas in my wings. My solution is to mix, i.e. one set of tanks
(either mounts or decos) are negative and the other set positive
empty. They balance out and I keep my drysuit inflated only enough to
provide comfort. Little if any weight is needed this way.
So, I could dive double Al 80s or Gen. 120s on my back and 72s for
deco/travel or 104s/ OMS 120s for back mount and Al for deco. Most
shops won't overfill and neither will the majority of truely portable
compressors so you get 104 cf or whatever the tank is rated to once
you're away from home and your source of gas. So what's the big deal
with the boat anchor back mounts? I have a temperamental back. The
less I strain it, the longer I dive. 104s hanging off me in high seas
whilst I breast feed and grab onto the pitching boat ladder with a
wing and a prayer is not my idea of being safe, fun or nice to my
back. I'd rather hand up the 72s or OMS 40s (loosing the extra
weight) and get in with the lighter Gen 120s or Al 80s and DR
manifold.
How bout it G-man or anyone else. What makes the floaters better for
stages and the anchors better for back mounts? Why shouldn't they be
reversed when wreck diving as in above when you can't get overfills or
don't want to lug your own compressor along or be carrying two anchors
onto the boat while trying to get up and in during the high seas?????
I know a studly answer is to work out and strengthen everything so the
heavy tanks aren't an issue. However, that will not change the fact
that the more massive tank will require more effort to support and
move quickly. This creates a safety issue on getting into the boat
after a deco. Do you or do you not want to add 30+ lbs hanging off
your back pitching as the furthest point out on the boat while you're
trying to get up the ladder? Think it might contribute to your work
load and the chance of bubble formation as well as the ladder failing
as it takes you and your tank's weight from the 10+ ft fall from the
last crest and tries to send you back skyward for a repeat?
Do you want to be nailed when a wave pushes the boat back on your head
'cause you couldn't move fast enough with the double anchors on your
back??? If you're an air-sucking hog and need the extra gas, start the
workouts and breathing exercises. If not and the gas supply isn't the
issue, then why the anchors? Got anyone to haul 'em up for you like the
hands do the anchors?
For those who want to breast feed off me, SMD. Sorry if any ladies are
offended. Offended men should have already unsubscribed per George.
Women who are offended that they should be treated differently, this
SMDs for you, lighten up.
Humor and trash asside, what's the scoop? Obi one, how 'bout you, you
may not be as cave blind as others.
