Topcon offers a wide range of automatic levels for the land surveyor, civil engineer
and contractors. All AT-G series levels feature a magnetically-dampened compensator
hung by four special mylar ribbons having superior resistance to cold, heat and shock.
They meet or exceed our rigid waterproof/dustproof standards. The AT-G4 and AT-G6
have been newly redesigned and are now available at even lower prices! The AT-G1
model features a 360° glass horizontal circle using a 25x magnification microscope
to read the circle
