The Bosch GLL 30 S Self-Leveling Cross Line Laser Level brings you top-notch accuracy at the flip of a switch. Place the GLL 30 S on a flat surface or on the included MM 2 Flexible mounting clamp and just like that, it’s ready! The laser lines are visible up to 30ft. The Smart Pendulum System self-levels and indicates out-of-level conditions to ensure accuracy. You can also lock in angles by manually adjusting the laser. The power switch not only turns on the laser but when it’s switched off it locks the pendulum system for safe transportation.

Power and Lock

Laser Line

MM 2 flexible Clamp
The MM 2 Clamp makes it easy to clamp anywhere for rapid setup.

Laser Line
Since the laser lines are straight you can move the laser and make a line at any angle. This would work great if you need to draw patterns on a wall or follow the incline of a ramp or staircase.
Best Use
- Find the slope
- Inspect grades
- Determine angles
- Working on a deck, driveway, angled projects
Things to know
The Bosch GLL 30 S provides simplicity and works right out of the box. The laser lines are fixed lines. What you see is what you get. You cannot select one or turn one off.
I ran a few tests with this and it proves to be pretty accurate. Your surface doesn’t have to be completely flat, as long as the laser is not leaning too much on either side, the tool levels itself out. The indicator lets you know when the device is not leveled. The flex mount is great, you can clamp the tool to practically any surface, like a door, ladder, leg of a chair or even to a tripod leg.
The GLL 30 S is priced at $79.97

The Bad

My Thoughts
If you are looking for a simple self-leveling tool then this is the one. I love the price! The cross line laser makes it really easy to use. With the MM 2 Flexible mount, you can conveniently clamp to nearly any surface for easy setup. For manual mode just tilt the laser to the desired angle.
