Bosch LR 1, Black, Blue

The Bosch LR 1 Professional laser receiver is a highly reliable tool designed to detect the red laser beams of rotary lasers, fully optimized for the Bosch GRL 400 H Professional and GRL 300 HV Professional construction lasers. This handy tool is ideal for both indoor and outdoor use, where it extends the measurement range to an impressive 200 meters. It thus helps to precisely locate the plane even at long distances or in bright lighting conditions, when the red beam is no longer visible to the naked eye.
The alignment of the laser beam is indicated both visually on a clear, dual-sided display and audibly via an acoustic signal, allowing the user to aim comfortably without having to constantly watch the screen. The receiver offers two selectable measurement accuracy levels—fine (±1 mm) for precise finishing work and coarse (±3 mm) for quick, rough leveling. The robust and compact chassis, weighing just 250 grams, features an IP65 rating, which guarantees complete protection against dust and safely withstands water splashes on the construction site. Power is supplied by a single 9V block battery.
