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

GLL 30 not so bright
Not what I expected from a Bosch tool. Very dissapointed , leaser not bright and horizontal line only about 5 feet long. Will return it for a better one.

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.

Perfect tool for the job
Easy set up - I laid it on the dining room table. Trying to level cabinet tops for new counter tops is tough with a 6' level. The GLL30 did the job with two twists of the positioning.

Laser is way too dim
I've tried using this for a few projects now from hanging cabinets to putting up siding and it's basically useless. If you're inside with no lights on you can see the laser ok but if you're outside it's pretty much invisible. I'm on a side of my house right now where the wall is 90 percent in the shade and the other small part is in the sun. I can barely see it in the shade and can't find it at all in the sun. I've used other laser levels in the sun and had no problem whatsoever. I could have spent a lot more money and gotten something better but I tried to go cheap and now I have a tool that is pretty much worthless...

Great for DIY
Bought this to supplement my manual 3 point level. The 3 point is more accurate but not near as quick and portable as this level. This is great for moving it around in inside work. I say inside because the beam gets pretty weak in brighter light.

But that is what I wanted, hang a picture, spot a row of nails, project a point from A to B with accuracy, laying tile in a small bathroom where the 3 point is just in the way. Kind of pricey but pays off in convenience. One of those nice to have modern tools.
