Product Features & specs :

Bosch GLL 30 30 ft. Self-Leveling Cross-Line Laser

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. 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
  • Class 2 Laser Product, < 1mW Power Output, Wavelength 635 nm
  • Manual mode tilt the laser to use the lines at any angle
  • Smart Pendulum system self-levels and indicates out-of-level condition
  • Secure transport pendulum locks when switched off
  • Ergonomic, compact and lightweight easy to use, easy to store

Needs level bubble on top!
Thus unit needs a level bubble on top of the unit to let you know if your going to be able to use it without struggling to get it within 4 degrees of level before you can start. If not, it just keeps flashing making you go through trial and error to see which way you need to adjust the unit. It could also be nice if you didn’t have to get it so close to level in the first place and just work like a rainbow.

easy to use
I purchased this tool to reset cabinets after replacing the flooring in my daughters home. I found it to work well. The brightness was acceptable but I improved it by turning of the kitchen lights.
Very happy with the product and would buy again. Wished I had purchased one years ago.

tool excellent
Use this to install vertical wall track at a commercial level. Excellent tool.
Need a case to hold the laser and BT150 tri-pod to protect it. Even a zipper bag would be good.

Really did a great job!
Had 12 shelf's to align, 6 on each side of a fireplace. Old fashion measuring and leveling would have taken hours. The product right out of the box did the trick. I also purchased the tripod stand and glad I did. Placing the Leveler on a ladder step would never have worked well. My only suggestion would be to include several examples of how to set it up and use in different situations would have saved trial and error time.

I bought this to do a bathroom tile job.
This little piece of ...... kept blinking, no matter how much I tried to level it to be within the +_4 degree.
there is no fish eye bubble or any indicator to let you know that the laser is level enough for it to function, so I basically have a strobe light that shoots out a crooked line.
Also the distance that I had to have it in to do my tub, was not far enough back, so I couldn't even see the horizontal line all around the tub tile area.
Do not buy this, spend some extra bucks and get a better laser.
