Topcon Auto Level


The AT-G4 and AT-G6 are water and dust proof and feature magnetically dampened compensators that level quickly and are resistant to ground vibrations, a must on active jobsites. And Topcon's exclusive mylar compensator suspension system resists temperature induced errors for consistent, accurate readings throughout the day.

Set-ups are a snap using the pop-up mirror for effortless viewing of the level vial without moving from the eyepiece, and fine horizontal adjustment knobs, conveniently located on both sides of the instrument, will get you on target in record time. The base circle is clearly marked in 1° divisions with numerical degrees marked every ten degrees.

The 26X magnification of the AT-G4 and 24X magni­fication of the AT-G6 offers clear, precise shots over distance, and both provide a super-short 1.6' (.5m) minimum focus.
