The Bosch GLL 30 Self-Leveling Cross-Line Laser projects two lines, making a cross-line projection, for a wide array of level and align uses. This versatility makes it more valuable than a typical line laser. With top-notch accuracy and one-switch operation, the user's leveling and alignment tasks are done quickly and correctly. The laser lines are visible up to 30 ft. The Smart Pendulum System self-levels and indicates out-of-level condition to help ensure an accurate layout, and it locks the lines at any angle. The pendulum system locks when switched off, to assure secure tool transport. The included MM 2 Flexible Mounting Device provides microfine height adjustment, and it allows the laser to be clamped on virtually any surface from 1/2 in. to 2-1/4 in. thick, for level lines at any height.
  • Cross-line mode projects two very bright lines that are perfectly level and plumb
  • Smart Pendulum system self-levels and indicates out-of-level condition
  • Manual mode tilt the laser to use the lines at any angle
  • Secure transport pendulum locks when switched off
  • Ergonomic, compact and lightweight easy to use, easy to store

I like it, it can be a little strenuous to set up but after you get it where you want it it works out fine the main thing is getting it level.

Poor self-leveling
Bought the product because it said it would work at any height level, even angled up. But it doesn’t do that very well. VERY basic tool for a very high price.

Disappointed because there is no way to lock the self leveling mechanism in order to set my own angle without the on-off laser lines.
It is a very basic laser level for the high price.

Leveling Shiplap
I bought the GLL 30 because my reclaimed shiplap siding on interiors walls project was taking forever with a standard level. This laser level increase my production rate by 4 times. Don't know what I would have done without it.
Wished I would have purchased the green laser lighted one since the red light is hard to see in well lit conditions.

A shopper on Oct 1, 2016
BEST ANSWER: The line laser can display a sold red line on a wall.
Does it. Work on ceiling grid ?
A shopper on Jan 19, 2017
BEST ANSWER: If you have a way to mount it level at that height then yes it would work up to 30ft. However, usually rotary lasers are used for that purpose
Can you select either horizontal or vertical, or is their only one mode/only crosshair?

New Vs. Reconditioned

What's the difference between New and Factory-Reconditioned?

Factory-Reconditioned products have been returned to the manufacturer and are restored to like-new operating condition; they go through a rigorous testing and inspection process. Plus, they offer a significant savings vs. new.
  • Reconditioned products may have minor cosmetic blemishes or scratches that do not affect item performance.
  • Reconditioned products may not come with all of the consumables the new version comes with (bits, sanding pads/papers, cases, etc.).
  • Both come with a manufacturer warranty and are covered by our Money Back Guarantee; New is 30 days, Reconditioned is 120 days.
