Nikon's unique automatic compensator employs a wire-suspended pendulum and an air damper to prevent magnetic interference. And the wide compensation range (±12' for AS-2C) makes it quick and easy to set up. Rugged construction provides excellent resistance to shocks. Highly accurate 1km double run leveling- AS-2C ±0.8mm w/o micrometer, ±0.4mm w/micrometer AS-2C features horizontal circle. Direct readings are graduated to 10' and can be estimated to 1'. The model AS-2C employs a 34x high-magnification, high-resolution telescope to assure sharp images even in poor light. Optional high- and low-power eyepiece lenses- AS-2C High-power 43x, Low-power 22x Improved minimum focusing distance, down to 1m/3.28 ft., for better performance in tight spots. Endless horizontal fine drive ensures smooth, precise pointing and angular measurement. To ensure rapid rotation, a new friction break does away with the need for clamps. Standard optical sight lets you find your target with precision and ease. A mirror with a pentaprism lets you view the circular bubble as an erect image while setting up and sighting. Attaches to both flat- and spherical-head tripods. Specifications for AS-2C Automatic Level Magnification: 34x Minimum focusing distance: 1.0m/3.28 ft.
