Our take on the Bosch GLL50-20G 50-Foot Green-Beam Self-Leveling Cross-Line Laser

The Bosch GLL50-20G is a self-leveling cross-line laser that projects green horizontal and vertical lines up to 50 feet. Green beams read up to four times brighter than red to the eye, which helps in brighter rooms and on longer runs. It is compact at about 1.2 pounds and rated IP54 for dust and water splash, so it handles job-site dust and light rain. Accuracy is 5/16 inch at 30 feet, which is fine for framing, cabinet and tile layout but not for precision machining. It is a bare tool: no battery, charger or mount in the box, so budget for AA alkalines or Bosch's 12V lithium-ion pack and a mount.

Questions and answers

Does it come with a battery?
No. It runs on AA alkaline batteries or a Bosch 12V lithium-ion pack, both sold separately. Add one to your order if you do not already own the Bosch 12V system.
How accurate is it?
Bosch rates it within 5/16 inch at 30 feet. That suits framing, cabinet and tile layout, but not precision machining or long exterior runs.
Can I use it outdoors?
The green line is hard to see in direct sunlight. It works best indoors or in shaded areas, and a detector is not included.
Does it have a 360-degree line?
No. It projects one horizontal and one vertical line as a cross. For full-room coverage you need a 360-degree laser.
How far does the beam reach?
Up to 50 feet, depending on light conditions. Visibility drops as distance grows and in bright rooms.
Is it self-leveling?
Yes, within its leveling range. Outside that range it blinks a warning, and the pendulum lock protects it during transport.
Where is the Bosch GLL50-20G 50-Foot Green-Beam Self-Leveling Cross-Line Laser cheapest?
