  • Two cross line projection; the Bosch GLL 2-15 is ideal for a really wide variety of jobs and applications. This is more than just a typical point level laser reason being it projects cross lines and at the same time it can project two lines either jointly or independently.

Whether it is for the free standing mode and or ceiling grid application setting up this laser will not give you any difficulties. You can also quickly adjust the BM3’s working height and lock it all thanks to the micro fine height adjustment system it is designed with.

What we don’t like;

  • Not that bright outdoors; the Bosch GLL 2-15 self leveling laser is a greatly efficient tool but just like anything else I discovered one minor con about the device. The laser is super bright when being used indoors but when it comes to outdoor usage it is actually not that bright more so under the bright sun. For people who are acquiring the laser for only indoor projects, this is absolutely no issue of concern but for those who want to also use it for outdoor projects the issue of it not being bright outside is a bother.
  • 50 feet visibility range; we have seen so many high quality lasers offering up to about 100 feet visibility range unfortunately the Bosch GLL 2-15 is only able to offer a range of 50feet and this is quite short. The only good thing is that its lines are very bright and visible in the short range that it offers.


The Bosch GLL 2-15 Self-Leveling Cross-Line Laser Kit includes the GLL-2-15 laser, BM3 positioning device, hard carrying case and finally a laser target. This cross line laser projects both the vertical and horizontal up to a range of 50 feet and it gives you the chance to choose whether to use each line on its own or use both of them at the same time using its user friendly key pad. The Bosch GLL 2-15 also features the smart pendulum system which helps you to work with only accurate measurements as it lets you whenever you level out of range. It combination of highly visible and a very sturdy construction makes this laser perfect for so many different layout and leveling applications.
