New RedLine family of tracking devices from Leica includes GNSS sensors for on-machine, vehicle and pole rover applications, a ground-based robotic tracker, and new software applications to speed construction measurement and layout tasks in every project phase. RedLine sensors are designed for construction use – light for measurement and layout, and tough enough for 3D machine control – and all sensors can be used for multiple construction tasks at every phase, including on-board machine control applications. The RedLine controller and software applications complete the family offering.
