The MILWAUKEE® M18™ Horizontal Rotary Laser 610m (2000') is ideally suited for exterior layout projects. Getting started with this laser is easy thanks to its simple, one-button setup, and it has been designed for harsh jobsite conditions, withstanding up to a 1.5m drop. Featuring built-in manual masking shutters, users are able to block the laser in any desired direction, preventing interference with other lasers on site. The Rotary Laser also features our ONE-KEY™ technology, for tool tracking and easy inventory management. The accompanying detector will detect the laser at a range up to 610m (diameter) and has built-in strobe light protection, reducing interference and downtime on the jobsite. With a high level of accuracy, this laser makes long-distance measuring easier.
