Topcon Theodolites Digital DT-309

The Topcon DT-309 you’ll be up and working fast, thanks to its simple interface and large, easy-to-see backlit LCD. There’s an optical plummet that makes set up over a control point easy, and a tilt sensor that provides ±3 minute angle correction. The DT-300 Series features a magnification of 30x, a super-short 0.9m minimum focus distance for those tight areas, and angle accuracies of 9 arc seconds.

The DT-309 Digital Theodolite features a lightweight, compact alignment and angular measurement device which boasts up to 30 workdays of power through an Alkaline or Li-ion , the highest water and dust protection in its category (IP66) paired with expert convenience.
