Subject: Fw: Dr. Bennett's Nitrox article
Date: Thu, 3 Feb 2000 17:01:53 -0800
I have copied a post that I have sent to rec. scuba, I have been going back
and forth over the last 2 weeks with Dr. Demento  A.K.A. as Dr. MJB.

It seems Dr. Demento believes that it is acceptable to use a P02 of 1.9, at
depth, in his * pony * bottle.  As I have been unsuccessful in getting this
idiot to see the light of way I thought maybe some on this list may want to
take a shot at showing our dear doctor the error of his ways.
