Unique modular construction of the Leica Redline product family allows the same automatic grade control sensors to be used across the entire construction site. The Leica Site Foreman application software provides a single, construction-oriented application on the Leica RedLine PowerController to handle all RedLine sensors for all construction site positioning needs. The RedLine is ready for every application from initial site surveys, through earthworks including 3D machine control, all the way through final as-built checks. Users have a single construction workflow-oriented application for all RedLine sensors for complete freedom to use the best technology (GLONASS, terrestrial-positioning-system satellite constellations, or both) for the job. Estimated list price: $15,000 to $45,000.
