Topcon GTS-900A


 Smaller-Lighter-Faster-Longer. The Topcon GTS 900 series of robotic total stations is the latest and most advanced system on the market today that boasts a completely new modern design, faster motors, wireless technology and X TRAC prism tracking technology.

The one touch quick locking X TRAC system set the standard for remote target acquisition in the robotics industry. Now this feature has been further refined to assure longer ranges, and faster target acquisition. The wireless RC-3 that is at the heart of the system increases range, utilizes the same batteries as the FC-200 field controller.

Available in 1, 3, and 5 second angle accuracies, gives you the option to select the accuracy that best fits your requirements. The 900 series offers flexibility, performance and industry leading technology all in one package. Take one for a test drive today.

The X-TRAC 7 robotic system upgrade is now available for the IS instrument. This enhancement to firmware and software affects the robotic tracking, quick-lock, radios, and data collector performance.

Contact your local Topcon dealer for details on where to obtain this X-TRAC 7 enhancement.
