Bosch GRL rotary lasers project a 360° level plane across large indoor and outdoor areas. With a receiver, they are used for foundations, slab and formwork levels, grading, drainage slopes and ceiling installation over long distances.
How to choose a Bosch rotary laser
- Horizontal and vertical (HV): HV models level horizontally and can be laid on their side for vertical alignment and plumb work.
- Range: with a receiver, these models work across a site diameter of up to 300m to 350m.
- Green or red laser: the green GRL 300 HVG is easier to see indoors without a receiver.

Rotary or line laser?
Rotary lasers are made for large areas and outdoor work. For interior fit-out, a Bosch line laser is quicker to set up. Mount your laser on a Bosch tripod for accurate height settings.
