Only Topcon provides a 3D grade control system featuring GPS+ technology to make stakeless grading more productive than ever. Topcon's 3D-GPS+ system has the ability to track both GPS and GLONASS satellites to ensure you won't have equipment downtime from too few satellites, a problem found in ordinary GPS-only systems.

• Fully Automatic control
• GPS+ technology for increased productivity
• Multiple machine capability
• Seamless addition to System Five control
• World's easiest-to-use operator interface - the System Five 3D control box

Topcon brings the future of machine control to you today with the revolutionary automatic 3D-GPS+ system for motorgraders and dozers.

Why upgrade?
3D-GPS+ is not only accurate to plus or minus one tenth of a foot, but it's also an incredible time saver! Because it uses System Five's valve control, it's fully automatic without installing extra components. There's virtually no staking or re-staking required because 3D-GPS+ works right from site plans and satellite positioning data. And unlike laser control, 3D-GPS+ allows the use of multiple machines even on hills, with just a single base station. Plus, you're free to move thousands of feet from the base station and still receive grade corrections via the radio. No headaches! Just fast, automatic grade control!
