Laser Systems EDM

The AutoRanger is a lightweight infrared EDM with a range of about two miles. It cost about $9,000 and was introduced in 1977. It was produced by Laser Systems & Electronics for its parent company, Keuffel & Esser. Together with K&E’s Vectron digital theodolite and handheld field computer, it formed a modular electronic surveying system. It was well received but soon displaced by more efficient and less expensive systems. The signature on this example reads "AutoRanger-S / Serial No. 06E6327 / AutoRanger Mfg. by Laser Systems & Electronics Inc. Tullahoma, Tennessee USA 118 / K&E Keuffel & Esser Co. Morristown, N.J. Made in U.S.A."
