Rotary laser level

BOSCH Professional GRL 300 HV Rotary Laser Level – Set with LR 1 Receiver, RC 1 Remote and Carrying Case

Level a whole site horizontally and vertically with ± 1 mm accuracy at 10 m.

The BOSCH Professional GRL 300 HV rotary laser level handles large-scale levelling work: foundations, formwork, suspended ceilings, screeds and partitions. The set arrives with the LR 1 receiver, RC 1 remote control and WM 4 mount, so one person can run the whole job alone. Working range reaches 60 m without the receiver and up to 300 m diameter with LR 1.

Horizontal and vertical levelling in one tool

The GRL 300 HV works in both planes, covering floor screeds and partition wall layout alike. Automatic self-levelling within ± 5° (8%) sets the plane for you once the tool is placed. No manual fiddling every time you reposition.

LR 1 receiver extends the range to 300 m diameter

The LR 1 receiver picks up the beam far beyond what the eye can see, extending the GRL 300 HV to a 300 m diameter working area – enough for an entire building plot. The RC 1 remote switches modes from the far side of the site, with no walk back to the tool.

Three rotation speeds plus line mode

Rotation at 150, 300 and 600 rpm gives a brighter line indoors and steadier detection outdoors with the receiver. Line mode concentrates the beam into a sector when you focus on one wall. The shock-warning function halts operation if the level is knocked, so an error never carries into the work.

IP 54 protection and 50 h of battery runtime

An IP 54 housing shrugs off dust and splashing water, so the level stays on site when conditions turn. Alkaline batteries deliver around 50 h of runtime, covering a long run of shifts without power worries. The supplied case stores the tool together with receiver and accessories.

Compatible with Bosch tripods and levelling rods

The 5/8" dual thread of the GRL 300 HV fits Bosch professional tripods BT 160, BT 170 HD and BT 300 HD in both horizontal and vertical setups. Height readings are taken with GR 240 and GR 500 levelling rods, while the supplied WM 4 mount clamps the level to a profile or wall edge.
