Topcon DT-209

The DT-200 series integrates the same high-quality advanced absolute circle reading technology found in Topcon' s high-performance total station products for more accurate field calculations; and they continue to deliver the highest quality optics and electronics you expect to find in Topcon theodolites. Available in three affordable models delivering 5 " , 7 " , or 9 " angle accuracy, there is a DT-200 theodolite perfect for any job. Like the DT-100 series, the DT-200 series weathers any wet or dust conditions in the field, allowing for a more productive day during inclement weather. All models are also compact and lightweight for easy portability; and their simple operation provides precise measurement in a functional, hassle-free package.
