Topcon Digital Theodolite DT-205 & DT 209
The DT-200 series integrates the same high-quality advanced absolute circle reading technology found in Topcons 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 sereies 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.
