See Exactly Where the Bucket Is. Dig to Grade on Your Own.

E2 is a guidance system, not an automatic control system. It does not move the bucket or control the hydraulics. It continuously shows the operator the real-time gap between the bucket's position and the design target, and the operator makes every cut manually based on that information.

E2 delivers ±1.5 cm horizontal and ±3 cm elevation accuracy under normal RTK operating conditions, with a bucket dynamic attitude accuracy of 0.2°. Actual results depend on correct reference-point setup, satellite visibility, and site conditions.

E2 is designed to mount on most mainstream excavators, including CAT, Komatsu, and Hyundai models, in both large and compact size classes.

E2 has built-in dual-SIM 4G and an adjustable-power UHF radio (0.5 W / 1 W / 2 W, 410–470 MHz), so it can receive RTK corrections via cellular network or a local base station without extra external modules.

Yes. The hardware is IP67-rated and rated for operation from -30°C to +75°C, and storage from -40°C to +85°C.

No. E2 (and Machine Guidance more broadly, as PRECISE currently offers it) senses and displays position information. It does not replace the operator's hands on the controls. If your project needs fully automated grading, that is a different category of system than what E2 provides.
