* Laser Colour: Green * Visibility range: 650m with receiver * Accuracy ± 1.5 mm/m at 30m horizontal, ± 3.0 mm/m at 30m vertical * Tripod thread: 2 x 5/8" * Laser class: 2 * IP rating: 68 * Batteries: 4 x AA & 1 x 4.0Ah The robust Bosch Professional GRL 650 CHVG rotary laser with Bluetooth® connectivity takes construction site levelling to new heights of precision and efficiency. Green beam technology delivers higher visibility in different lighting conditions. The rotary laser is sturdily built to operate in rough site conditions and bad weather, withstanding up to 2m tripod tip-over and meeting IP68 dust and water protection standards. Using the Levelling Remote App for settings overview and remote control saves time and allows total focus on the job. The versatile GRL 650 CHVG Professional is best used on outdoor levelling and grading jobs as well as interior wall, ceiling, and HVAC installation. Long runtime convenience is provided by a dual-power option that uses Bosch rechargeable 18 V Li-ion or alkaline D-Cell batteries. Optimal convenience thanks to high-tech features such as display, dual slope, slope memory, and high-quality receiver LR 65 G receiver.
