Subject: Re: Fw: Nitrox Stick
As far as I know, you are correct. Garbage In - Garbage Out.

It is similar to the system sold by MasterLine that blends air and oxygen prior
to the compressor or the IANTD Quick Gas continuous flow system that also mixes
before the compressor.

IANTD, for example, states in its literature that the system " Safely blends all
EANx mixtures with any oil free or oxygen compatible scuba compressor".

Perhaps, that's why I use a RIX compressor for my continuous blending system.
Just broke down a set of twins over the weekend that had seen heavy duty use
since the compressor and continuous blending mixer was installed in June -
spotless.

I thought the stick was Canadian but could be wrong. Again, the problem isn't
with the stick or any other system. Its with the compressor.
