The professional laser is made with three modes including cross line, horizontal and vertical modes which either project two lines together or each one on its own. This laser is also made with the manual mode which allowing you to lock the cross line when you are not using it and at the same time gives you to use the tool at any angle that you feel most appropriate. When put next to a wall this, laser delivers a very long vertical line which extends visibility almost to 360degrees while all the other lines remain brilliantly visible all the way to 50ft.

It features a light indicator which helps you to know whether the laser is locked or unlocked so you won’t have to worry about anything moving around with your tool when it is this well kept.

What we don’t like:

  • Limited visibility range; if you compared the Bosch’s GLL 55 self leveling laser to some other lasers of the same type you will find that it is among those with limited visibility range. And much as it is very efficient at covering up an entire room layout, its visibility range can only go up to 50ft. this makes it quite tiring for those working in bigger spaces.


Overall I would clearly say the Bosch GLL 55 Self-Leveling Cross-Line Laser is a really great laser reason being even after going through lots and lots of reviews about the tool I barely came across any complaints about it. Infused with advanced VisiMax technology, this laser offers exceptional visibility in all site conditions while preventing the tool’s diodes from overheating to ensure added durability. Its smart pendulum system eliminates guess work and inaccuracy for both novices as well as professionals as it alerts you whenever you make there are any lines that are not accurate. The GLL 55 is extremely to use thanks to its magnetic L mount with free standing mode that makes it super easy to set up the tool for use while its user friendly key pad enables you to set the laser to any layout mode with ease. It also offers really efficient job layout with different modes to perfectly cover up a whole room as its super sturdy construction makes it more than ready for absolutely any job site conditions including the tough ones.
