Very short 0.5 meter focussing (AT-G3/G4/G7N) AT-G3/G4/G7N have a short range setting position of 0.5 meter that is especially suitable for close range work carried out by builders and contractors. Easy-to-see circular level observation The circular level is checked very easily with a slight shift of the eye. There is a clear distinct view observed via reflecting pentagonal mirror (AT-G1/G2/G3) or a hinged mirror (AT-G4/G7N). Rapid, stable automatic levelling A time-proven magnetically damped compensator is incorporated for automatic levellingaction. It is not affected by fine vibrations and has been proven to have very stable precision,thus speeding up automatic levelling operations and producing accurate results. The Topcon- exclusive automatic levelling system utilises four special mylar ribbons for hanging the magnetic damper compensator. The compensator is therefore not influenced by the magnetic field, aswell as having superior resistance to cold, heat and shock. Rubber eyepiece cap Sighting through Topcon’s AT-G series is safe for anyone who wears eyeglasses. With theirprotective rubber eyepiece caps, scratches and abrasions are reduced or eliminated completely. Fast instrument set-up Very fast instrument set-up is possible using a dome head tripod. The base plate is specially shaped for fixing on top of dome head tripods.

Diagonal eyepieces (AT-G1/G2/G3) By using the diagonal eyepiece in place of the standard telescope eyepiece, easier viewing is possible with low set-up positions or in confined spaces. 40x eyepiece (AT-G1/G2) Increases magnification of the telescope of the AT-G series from 32x to 40x for even more precise levelling. Illuminator-5 (AT-G1/G2/G3) Provides light to the telescope reticle when available light is insufficient, for example in tunnels or at night. Optical micrometer (AT-G1/G2/G3) Get greater accuracy from AT-G series auto levels using the optical micrometer. In one kilometre of double runlevelling, accuracy is improved to ±0.4mm. The optical micrometer attaches to front of objective lens with acounter weight attached to the eyepiece. Centering platform When used on top of a tripod the centering platform provides quick and simple centering on reference points. Parallel shifts of 100mm vertically and 30mmlaterally.
