I'm equally happy with either.

Also before it gets asked I know what my instructors thoughts were on the subject and my own, but I also don't really do too much "deep" diving (below about 120ft) or currently multi stop deco requiring more than short stops on back/side gas then O2 at 20ft and up.

One of the main reasons for it was (and still is) is simply logistics. O2 comes in K bottles filles to ~2200 psi. Its much more difficult to get 2000 psi fill of O2 even with a cascade of bottles.

With 80% one can fill what they can and then top a bit with air to get the pressure higher.


The arguments for 100% over 80% have been long rehashed though. Much more effecient to just read through some past threads on Deco Stop if one is interested. ]]> KMD http://www.divematrix.com/showthread.php?10178-1.6-MOD-vs-1.4-MOD-for-Labeling-Deco-bottle
