MikeFerrara:A real dummy can survive getting gear from a LDS and diving it. If you take the LDS out of it you have to replace it with something. Whether you get some one else to do it or you just get smarter yourself something has to be done. However if a diver stays a dummy and jus gets their stuff from LP they're missing the boat.
That is not necessarily true.
I've seen a very high percentage of dummies in LDSs.
Folks who are too dumb to use a calculator, as an example. What are the odds they understand a negative pressure test?
