Never actually used a circular one except for aircraft navigation. In college I used a Deitzen (sp) Log Log Duplex Decitrig which was more or less the standard and in it's brown leather case hung at the side of almost all Engineering students. After college I used mostly a 6" Post or Pickett (can't remember as that was a LOOONG time ago) that was Aluminum and If memory serves was Yellow. Most carried it in their pencil protector in their shirt pocket. As far as global warming goes for every expert you show The other view can show an equal number with equal qualifications. Seems like I remember that all the hoopla about faking data came from British Universities, but that too was probably exaggerated here in the colonies. From some studies I have read all the pollution since the beginning of time attributed to mankind is surpassed by even the eruption of Mt St Helen much less Krakatoa in the 1800's which left the skys changed around the world for several years. Now wheather these are facts or opinions I will certainly leave up to your superior intellect as I am reluctant to make such positive statements of knowledge my own self. I actually once had a liberal thought but on further introspection realized I was incorrect.
