If you are a contractor or consultant wanting to use survey-grade RTK for other things when not in use for Ditch Assist then the Hemisphere S321 should be on your short-list. Extremely rugged, and offering excellent performance for both Ditch Assist and surveying. The S321 receivers feature built-in Bluetooth for wireless NMEA out when surveying, and also include a built-in cellular modem and internal software for use on VRS or CORS networks. Simple to configure via any web browser, and can be powered by removable batteries (2x batteries included which should get you through a 4-6 hour day). The S321 has built-in 430-470MHz radios for long transmission ranges.

Fully automated machine control for scrapers, ditchers, pulldozers, land levelers, and non-pitch tile plows. Create best-fit slope drainage ditches, fixed or variable slope land leveling planes, or implement advanced 3D land forming designs from programs such as OptiSurface, AgForm3D, or WM Form.
