The Bosch GRL4000-90CHVK-S is engineered for the most demanding infrastructure and heavy civil construction environments. Its core strength lies in a massive 4000-foot operational range when paired with its included laser detector, allowing a single unit to control grade and alignment across multi-acre job sites, road projects, and extensive excavation work. This capability is complemented by dual-axis slope control, enabling precise compound grade setting for continuous drainage planning and complex earthworks. Durability is paramount, with an IP68 rating guaranteeing operation and survival in torrential rain, dust storms, and routine washdowns. The system is sold as a complete kit, which is a critical advantage for professional crews.
It includes a rugged tripod, a grade rod, a remote control for convenient adjustments, and a high-sensitivity receiver, ensuring teams have everything needed for immediate deployment without chasing additional equipment. Accuracy is maintained at a professional standard of ±1/8 inch at 100 feet, which is essential for projects where minor errors lead to costly rework. This laser is the definitive choice for municipal public works departments, heavy civil contractors, and large-scale site survey teams. It represents a significant capital investment but is justified by its ability to enhance productivity, ensure precision, and provide unwavering reliability on projects where downtime or inaccuracy is not an option.
