The Bosch 18V REVOLVE4000 Connected Self-Leveling Horizontal Rotary Laser with uCAL user-calibration delivers a comprehensive solution for precise outdoor and indoor leveling. It has a Dual Dial-In Slope feature that allows slope angle adjustment on both the X and Y axes, for grading applications. This laser is powered by a Bosch CORE18V 4.0 Ah battery, providing extended runtime. The rotary laser is compatible with 4.0 Ah and 8.0 Ah Bosch CORE18V Li-ion batteries. It also features an alkaline adapter to use four (D) cells. The REVOLVE4000 is engineered with a cage overmold and an innovative handle design, and it is built to IP68 dust- and water-protection standards. It features Bluetooth® connectivity to a connected device, linking to the Bosch Leveling Remote App. This app controls on/off, Dual Dial-In Slope, and more. The rotary laser features uCAL, for user-calibration, taking the user step by step through the calibration process. This avoids tool down time and provides confidence that the laser is accurate. It delivers accuracy of ±1/16 In. at 100 Ft., and a range of up to 4,000 Ft. with laser receiver.
