Accuracy on the jobsite has always mattered. What’s changed is how much margin there is for error.

With tighter schedules and fewer hands on site, contractors are looking for ways to get grading right the first time—without slowing crews down or relying on constant manual checks. That shift is driving interest in machine control systems that use GPS-based positioning to provide real-time guidance directly in the cab.

Advanced 3D machine control solutions for modern jobsites

Benchmark Tool & Supply has partnered with CHCNAV to make advanced machine control systems easier to adopt and easier to support on real jobsites. CHCNAV provides 3D machine control solutions for excavators, graders, and dozers, while Benchmark Tool & Supply handles sales guidance, installation, training, and ongoing support (remote support plus on-site help).

For contractors looking to modernize earthmoving operations or move beyond traditional grade checking methods, this partnership improves access to machine control.

Machine control solutions for excavators

Excavation work often involves changing depths, evolving designs, and variable site conditions. CHCNav offers two excavator-focused solutions that support different levels of complexity.

EasyNav EMG100 is typically the entry point for contractors who want immediate grading guidance without adding complexity. The system allows operators to make in-field design adjustments directly from the cab, eliminating the need for pre-built models. Network-based corrections remove the need for base station setup or localization routines, and the multi-constellation GNSS antennas improve performance in areas with tree cover or partial obstruction.

For contractors running higher-production excavation work, CHCNAV's TX73 adds more advanced workflow support while keeping usability front and center. Operators can customize screen layouts, access shortcuts, and see live 3D updates as designs are adjusted. Changes can be sent directly to the machine without stopping work.

Machine control solutions for graders

Grading requires consistency over long runs, not just point-to-point accuracy. CHCNav’s TG63 grader system is designed to support automated blade control using GNSS positioning, helping operators maintain grade and slope with minimal manual intervention.

The system uses GR-Tech technology combined with GNSS and IMU positioning at a 100 Hz update rate to deliver reliable 3D accuracy during fine and rough grading. Operators can import and edit template designs easily, reducing dependence on manual staking and allowing work to continue without repeated grade checks. TG63 is designed for fast deployment, with calibration typically completed in about 15 minutes and full installation in under five hours, helping crews get back to production quickly.

Machine control solutions for dozers

Bulk earthmoving with dozers demands repeatability and smooth control, especially when working across uneven terrain. CHCNav’s TD63 dozer system combines GNSS positioning with a high-frequency IMU sensor to support automated blade control during both rough and finish grading operations.

The system tracks all major satellite constellations and operates at a 100 Hz update rate, providing centimeter-level precision and stable blade guidance. TD63 supports multiple file formats and cloud-based synchronization, allowing design data to move easily between the office and the machine. Operators can switch smoothly between 2D and 3D operation modes depending on job requirements, and the system is designed to grow with the operation through upgradable guidance capabilities. Typical installations can be completed in approximately two hours, with calibration taking about 15 minutes.

Next Steps

CHCNAV 3D machine control systems are cost effective, reliable and easy to use, backed by Benchmark’s reputation for hands-on service and field integration.
