Bosch GRL 300 HV Professional Rotary Laser Set

The Bosch GRL 300 HV Professional Rotary Laser Set is a rotating laser level for horizontal and vertical alignment and levelling in construction, renovation, and installation work. It self-levels within ±5° at an accuracy of 0.1 mm/m, providing a reliable reference for layout and transfer tasks. The red laser beam reaches 60 m on its own and 300 m with the included LR1 receiver. Rotation at 600 RPM produces continuous reference lines in both horizontal and vertical orientations across the work area. This working range and rotation speed make the set suitable for establishing reference lines in large indoor spaces or outdoor sites.

An IP54-rated housing resists dust and water splashes for consistent operation on construction sites. A rechargeable battery provides up to 30 hours of operating time per charge. One-button operation with an intuitive display keeps the interface straightforward, and an automatic shock-warning function alerts the user if the instrument is disturbed during levelling. A 5/8-inch tripod mount allows attachment to standard surveying tripods. The set includes the rotary laser, an LR1 receiver, an RC1 remote control, a BT 300 HD elevator tripod, a GR 240 levelling rod, and carrying accessories.
