GTS-220 series

TOPCON proudly announces the debut GTS-220 Series as the innovative successor to the best selling GTS-210 Series Total Stations.

The GTS-210 Series with "Waterproof" design brought revolution to the surveying industry with features and durability.

Now the new GTS-220 Series has up-graded its basic functions for distance and angle measurement in addition to maintaining superb durability against the environment.

The GTS-220 Series is also provided with a longer life battery of 10 hours, and various kinds of application programs makes surveying work quick and simple in the field.

The features included with the "All Weather" highly productive GTS-220 Series Total Stations are setting a new standard for surveying!
