AGA EDM (Geodimeter Model 8)

Description
The Geodimeter Model 8, introduced in 1967, is a long-distance geodetic instrument with a helium-neon laser and transistorized circuitry. It used a 12-volt battery, weighed 51 lb., and cost about $16,000. It was assembled in Paramus, N.J., but the components were made in Sweden. This example is marked "AGA CORPORATION GEODIMETER MODULATION SYSTEM BJERHAMMER Model 8 no. 81008 MADE IN U.S.A." It belonged to the United States Coast and Geodetic Survey, and was probably used on the trans-continental traverse, a precise measurement of the length and width of the United States.
