I just returned from 4 days of Tek'95 in San Francisco. I was very impressed
with the caliber of participation. Teckies are not dumb, just a little crazy!
I heard some impressive papers on cave diving, rebreathers, physics of bubble
formation, legal aspects, archaeology, etc. My first impression of the tech
diving community is that there are some very bright, intense, dedicated people
of both sexes who do this kind of thing. Having built my first rebreather in
1954, I really can appreciate the changes that have occurred with rebreathers,
especially, with the advent of electrochemical o2 sensors and microprocessor
controlled gas valves, dive computers,etc. This has inspired me to build
another rebreather....for my own use. If anyone is interested in plans for a
rebreather, try to locate "Shallow Water Diving" by Schenk and Kendall (1950).
This is where I learned to build my own equipment. But please be careful and
understand thoroughly what you are doing.
Another note. I just bought an unused military Russian rebreather for $50.
Quite a deal, but the throw-away cannister is irreplaceble. It's good for 3
hours underwater. (Stormin) Norman Thomas
