110' ? bah ... 220' now you're talking.

220'? Not without a buddy I am VERY confident in, dual tanks, a pony
bottle, three dive computers (two-fault tolerance!) and a couple of
decompression stages with tanks, thankyouverymuch! Oh, yeah - and a
fully-staffed chamber within a mile of the dock, just in case.
