DKM1-.02MIL

258514 THEODOLITE - DKM1-.02MIL refers to the Kern DKM1 Gyrotheodolite, a high-precision, compact surveying instrument from the mid-20th century, known for its accuracy (down to 0.0001 gon with its micrometer) and use in demanding geographic expeditions before GPS, relying on brass and glass construction for determining true north (azimuth) via a gyroscope - Manufacturer: Kern (Aarau, Switzerland).
Type: Gyrotheodolite (Gyro-Theodolite).
Function: Determines geographic azimuth (true north) using a gyroscope, essential for precise surveying.
Accuracy: Micrometer allows readings to 0.0001 gon (gradian), or 0.000035 degrees, highlighting its precision.
Design: Small, heavy for its size (due to brass), olive drab color, used in expeditions where weight mattered.
Era: Mid-1950s design, popular before Global Navigation Satellite Systems (GNSS) - USED 1978
