Rated 4 out of 5 by from Great laser for the price! I work in a hospital and do alot of work in offices or patient rooms no bigger than 20x20 and this laser is more visible than my red 360 laser! Great for an interior professional or DIY'ER! Is this model compatible with a detector to increase the range? Thanks!

Rated 2 out of 5 by from Alright but... I've had this laser level for about 2 months. There are good thing about this and some bad things about it. Good: easy set up and clear green line. Negative: it uses batteries quickly. And due this the battery ports don't connect well after a couple of changes. I can't get the laser work unless I have the batteries just right. Not working right now with new batteries. Also the switch has to be toggled several times in order to get the laser on Maybe I have a faulty one because Bosch usually has excellent tools. Kinda disappointed with the whole tool.

Is this laser suitable for outdoor use?

Asked by: Alex
No, the GLL40-20G can only be used indoors. For outdoor applications, we recommend using the GCL 2-160 or GLL3-330C/CG. For further assistance, contact us at 1-877-BOSCH99 (1-877-267-2499) from Mon-Fri 7A-7P CST.

Can this be tilted back to have a line across the ceiling or will it shut off like if it's tilted sideways? Thanks in advance!

Asked by: AlphaCo
The GLL40-20G Green Laser Tool does not feature manual mode. Therefore, the unit cannot be tilted for a steady line on the ceiling. We would recommend a 360° Plane Laser that projects laser to the ceiling like our GLL3-300. For further assistance, contact us at 1-877-BOSCH99 (1-877-267-2499) from Mon-Fri 7A-7P CST.
