Rotary laser level

BOSCH Professional GRL 300 HV Rotary Laser Level — Set with Tripod, Receiver and Case

Horizontal and vertical levelling across a 300 m diameter with the receiver — built for construction sites and layout work.

The BOSCH Professional GRL 300 HV rotary laser level projects horizontal and vertical reference planes across the whole site — 60 m diameter with the visible beam and up to 300 m diameter when used with the laser receiver. A red class 3R beam and ±3 mm at 30 m accuracy suit formwork, excavation, screeding and partition installation. The set arrives with receiver, remote control, tripod, measuring rod and carrying case, ready for the first job.

Horizontal and vertical planes from one tool

The GRL 300 HV works in both planes, so one setup covers screed and ceiling heights as well as vertical references for partitions and façade details. With the receiver the working range reaches a 300 m diameter, covering most of a site from a single position.

Automatic self-levelling within ±5° for a fast start

The laser levels itself within ±5° (8%), removing fiddly manual adjustment on uneven ground. A shock-warning function reacts to knocks and vibration so you never work from a shifted reference line.

IP54 protection for outdoor use

IP54 protection shields the GRL 300 HV from dust and splashing water, so it can stay in position through site dust, wind and light rain. An operating range of -10 to 50 °C covers both winter and summer jobs.

Remote operation with the RC 1 handset

The included remote control switches modes and rotation speed without walking back to the tripod — handy when the laser sits high up or in another room. The laser receiver shows which way to correct wherever the beam is not visible to the eye.
