I started green, as a rodman in Grand Junction, Colo. surveying 36" natural gas pipeline in 1978. I quickly advanced to insrumentman in 6 months. My first instrument was a Paragon A & E transit. We got our distance w a chain. (at that time we didn't have anything to "roll it up" w and learned to lay it out and collect in a loop and twist it into a smaller loop!)! That was great! Hell, it was snowing a ton! The first distance meter we got in 1979 was a Hewlitt Packard distance meter w about 10 knobs across it that each one had to be "fine tuned" for it to get the distance! The rodman had to hold it still a long time for a distance!! We advanced to a theotolite that was still read w a magnifying glass (the eye) like the Paragon!! Well, all for now.
