01 · The pitch

For too long, machine control has been overly expensive and complicated to use. If you're a single machine operator or a civil firm looking to scale — we solve that problem. Pegs, lasers and someone in the trench? Forget about it. Millimetre accuracy, installation in hours, and full training and support so we're with you every step of the way. We will save you tonnes while you move every tonne to grade.

02 · The business case

Run your own numbers

Machine control pays for itself in saved passes, less rework and no stakeouts. Crunch the savings — or build your own quote in a minute.

01

Stop paying for rework

Precision

The TX73 computes bucket-tip position in real time against the design model — 1 cm horizontal, 1.5 cm 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 fifteen 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.

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.

Feel the crosshair

Drag the bucket below grade and watch the HUD react — the same cut/fill logic our displays show operators in the cab. Switch between 2.5D depth guidance and full 3D model view.
