The second word is 3 Te 2 Ka Pe. I used Windows Character Map to get the names of the characters (and to write Cyrillic in the earlier message). Not being a Russian speaker, I may have made some mistakes. E.g., Cyrillic has a letter which resembles digit 3. > Not suprsising that they are out of business. > How many years ago did it > cost $1200 new? About 6 years ago, I think. The market for non-electronic theodolites has decreased. Most professional surveyors use "total stations" which combine a precision distance meter with a digital readout theodolite. The instrument can dump its data into a computer. This is much faster than delicately bringing an optical micrometer into coincidence, reading the angle, and recording the observation in a notebook. To a professional, time is money, and the expensive instrument soon pays for itself. -- I block messages that contain attachments or HTML. --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to NavList@fer3.com To , send email to NavList-@fer3.com -~----------~----~----~----~------~----~------~--~---
