I am not trimixed certified, but at 100 feet does 30/30 gove your more bottom time than ean 32? it I am 30 he can I stay longer at 100 feet vs nitrox 32? thanks!

However, there are numerous other benefits to using 30/30 vs 32%, such as reduced breathing effort and an associated reduction in CO2 production & retention, a lower narcotic level, and in my opinion you just feel better. The latter may just be a result of doing a proper ascent. As an aside my wife and I currently dive 30/30 the same as 32% (single tank) and have not had any problems.

I love helium but I can't see divers who cry over a $5 tank of air ever paying for trimix for the same dive.
Even mixing it yourself it gets expensive not to mention time consuming.
The question as stated makes no sense, or seems to be based on a flawed assumption. You can stay on the bottom as long as you want with either gas. Then you'll have to do the correct deco. For a short bottom time it would be about the same deco with either gas. 100ft is a little deep for nitrox anyway.wolfpack once bubbled...
at 100 feet does 30/30 give you more bottom time than ean 32?

Helium is pretty expensive here in the Lower Keys. For me to fill a set of doubles (200 FT3) costs me about $30 in helium alone.
