Leveling Features

The Bosch GLL 2 is a self-leveling laser line level, meaning you don't have to tediously adjust the level to make it project a true level or plumb line against a surface. In fact, you can place the level approximately four degrees out of level and the internal pendulum will adjust the difference, making the projected line perfectly level. If the level is placed at a greater degree out of level, an LED at the top of the unit turns red and the projected lines flash, which means you have to adjust the tool at a better angle. If you bump or move the level while it is in self-leveling mode, it only takes about three seconds for it to find level again, which is convenient and fast.

However, you have the ability to lock the pendulum in place if you need to project an out-of-level line against a surface. This feature is especially useful if you want to paint a staircase wall two different colors, hang pictures at a specific angle and so on.

Projection Range

This level is capable of projecting a clean, visible line up to 30 feet away, while retaining a high level of accuracy. Indeed, at 30 feet, the level is accurate up 3/16 of an inch, which is the most accurate out of all the levels we reviewed. On top of that, the level projects the horizontal line at 120 degrees, which isn't the most impressive angle we have seen but is still noteworthy. With this wide projection range, you can cast a level line across two walls at once. This is useful for many tasks, such as hanging pictures, painting walls two colors and hanging railings.

Additionally, this level is capable of projecting single horizontal or vertical lines, as well as both lines at once, creating a cross-line laser. This feature is especially useful if you need to tile a bathroom or kitchen.

Design

The Bosch GLL 2 is a light, compact unit that is easy to carry and move around. The tool requires two AA batteries, which are included with the tool, and they power the unit for approximately 15 hours before needing replacement. This battery life is not the best out of the laser lines we reviewed, but it is still significant, and you don't have to worry about keeping spare batteries with you at all times.

This laser line level has standard, quarter-inch tripod threading, which means you can use most camera tripods to set this level up. Included with the level is a clamp mount that extends up to 2 1/2 inches, allowing you to attach it to a number of surfaces, which enables you to use the level in a variety of places and for various scenarios.

Summary

The Bosch GLL 2 is an efficient tool that is easy to set up and use within moments to create a perfectly level or plumb line. The cross-line laser level projects lines at a wide angle, allowing you to cast a line across an entire room, which can save you the time of finding the same level line over and over. This level can also project an accurate line against a surface up to 30 feet away, which isn't the best we have seen but is still effective. Ultimately, this is a great laser line level that can serve you in a variety of ways for any type of project you encounter.
