Waterproof sealed telescope construction. The AT-G series have a completely waterproof telescope and are therefore ideal for all kinds of levelling work, even in wet conditions, in rain or in tunnels.

Only test-approved telescopes are used and dry nitrogen gas is sealed in the telescope tube. This effectively prevents lens clouding and moisture condensation.

The AT-G series automatic levels are all water sealed to IPX-7, offering the maximum water protection.
Angular reading to 10 minutes (AT-G1) The model AT-G1 has a glass horizontal circle which is graduated in 10 minute divisions (10c divisions) and numbered every degree (one grade) with calibrations from 0° to 360° (0g to 400g). Furthermore, readings are possible through a 25x reading microscope, with only a slight shift of the eye, from the telescope eyepiece.

The horizontal circle freely rotates
for zero alignment. 2 speed focussing (AT-G1) Fine and coarse focussing is provided by a coaxial focussing knob, which permits both rapid setting and accurate focussing for a perfect image.

New ergonomic design Redesigned for smoother, easier operation all around, Topcon’s AT-G series offers
a larger knob for faster, accurate adjustments and new materials for lightweight when on the move.

Clampless fine horizontal adjustments Fine horizontal adjustments are possible at any point through 360° (400g), without clamping action. This means that
target alignments are greatly speeded up. Furthermore, fine
horizontal knobs are available on both sides for very easy and
speedy adjustments.

Rubber eyepiece cap
Sighting through Topcon's AT-G7 is safe for anyone who wears eyeglasses. With their protective rubber eyepiece caps, scratches and abrasions are reduced or eliminated completely.
