Every bucketon grade.
2.5D and 3D machine control for excavators and dozers — millimetre-accurate CHCNAV guidance, retrofitted to your machine. Supported locally by Green Grade.
Run your own numbers
Machine control pays for itself faster than you think. Almost zero reworks, no stakeouts and access to a bigger pool of project opportunities. Crunch the savings — or build your own quote in a minute.
Illustrative estimate — tune with your own numbers. Actual savings depend on project mix, soil and crew.
Projected annual saving

Across 3 machines at 40 h/week with a 15% efficiency gain.
Stop paying for rework
Precision
The TX73 computes bucket-tip position in real time against the design model — 10 mm horizontal, 15 mm vertical. No guesswork, no over-excavation, no paying twice for the same dirt.
Digging the same morning
Speed
Mount in under two hours. Calibrate in thirty minutes. First cut the same day. Less time setting up means more time digging — and every operator sees live cut/fill on the display. Our EasyNAV system can be installed in under 2 hours.
Fits the machines you already run
Compatibility
Swing boom, triple boom, tilt bucket, offset boom — the EMG100 fits them all. The TX73 adds automated tilt control for Engcon and Steelwrist tiltrotators. If it digs, we can guide it.
One screen for the whole fleet
Control
iSite cloud keeps every machine current with over-the-air updates, remote troubleshooting and data sync — while as-built views make progress visible to the office, not just the cab.
