Topcon AT-G2 Auto Level 32X for Surveying in Great Working C

Topcon AT-G2 Auto Level 32X for Surveying
In great working comdition!!!

 Features:
Waterproof
2 Speed Focusing
Clampless Fine Horizontal Adjustments
Fast Instrument Set-Up


Topcon's AT-G2 level has a completely waterproof telescope and is , therefore, ideal for all kinds of wet-surveying operations, in light rain or tunnels.

2 speed focusing. Fine and course focusing is provided by a coaxial focusing knob, wich permits rapid setting and accurate focusing for perfect image at the same time.

Very fast instrument set-up is possile because the base plate can be usen for fixing on top of dome head tripods.

The circular level is checked very easily with a slight shift of the eye, with a clear, distinct view observed via reflecting pentagonal mirror.

Atime-proven magnetically-dampend compensator is incorporated for automatic leveling action. It is not affected by fine vibrations and has been proven to have very stable precision, thus speeding up automatic leveling operations and producing accurate results.

The Topcon-exclusive automatic leveling system utilizes four special mylar ribbons for hanging the magnetic damper compensator, wich is , therefore, not influenced by the magnetic field, as well as having superior resistance to cold, heat and shock.
