    These theodolites were used by USN meteorologists to track weather balloons, also known as pilot balloons, to measure high altitude winds.  This type of theodolite is often referred to as a Pibal (from Pilot Balloon).   As best as I can tell, this type of instrument was not used for navigation, though it does work on the same principles as a sextant.   I would appreciate further information from other members of this group.

    Subject: [NavList] K & E Marine Theodolite (ebay)

    A K & E Marine Theodolite is listed on ebay under the title "USGI WW2 Keuffel & Esser Co. Air Navigation Sextant". Is anyone familiar with this device? I am not a potential bidder, just curious if anyone has used one. Brenner's Pilot Balloon webpage names it K & E Marine Theodolite.
