Reliable and Bright
Bosch’s GRL 300 HV self-leveling rotating laser projects 90-degree plumb and layout lines for squaring, with the laser plumb line continually available for the 90 degree layout of walls. Both horizontal and vertical beams are also conveniently self-leveling. The bright, highly visible, laser lines use smart laser technology to adjust laser luminosity while the rotating is occurring to promote maximum visibility and, at the same time, maintain safety class 2. It has a full array of beam enhancements, including variable speed selection and variable scan angles for maximum visibility in a range of light conditions. Also, the Bosch GRL 300HV has a very solid top housing assembly, which provides housing protection and access to the rotating head. The overall combination is robust, simple, and reliable.

Sturdy and User Friendly
Bosch’s GRL 300 HV self-leveling rotating laser is IP54 rated, which means that it’s protected against dust and water, providing a longer product life. The battery tray is conveniently located to provide easy access to batteries and changing. There is a tactically oriented keypad that’s recessed and features a variety of functions, such as a single on/off button, variable speed rotation (there are four preset speeds), variable scan angle (there are four preset scan angles), a battery level indicator, and a disturbance monitor. These functions can also be replicated on the included pocket-sized remote, which comes in handy especially when the laser is mounted within hard-to-reach areas.

Multiple Applications
Thanks to its self-leveling rotation, bright lines, sturdy construction, and helpful features, the GRL 300 HV self-leveling rotating laser is an asset with a range of applications, including helping with projects having to do with ceiling installation, computer and access flooring, concrete interior, demountable walls, electrical and lighting installation and work, fire sprinkler leveling and layout, general leveling and layout, HVAC ducting and vents, partitions, wall stud installing, and others.
