Laser levels are becoming more and more popular. It is easy to see why their popularity has increased so much. They can take the place of multiple tools (level, plumb bob, chalk line, pencil marks, etc.) Our Bosch Cross Line Laser Level Review will go over how easy these tools can be to use.

Bosch Cross Line Laser Level Review Overview

Laser levels have become more popular recently because their price and size have dropped considerably. This review centers on the simple Bosch GLL 30. This particular model projects two perpendicular red laser lines. One vertical (Plumb) and one horizontal (Level).

The included mount makes for securing the laser in the perfect position quite easily.

The OFF/ON switch is easy to see and manipulate, even with gloves on. When the unit is switched off, it also locks the pendulum to prevent damage when not in use (during transport).

The edges and corners have rubber over molding. This helps protect the unit in case of falls, as well as makes gripping the unit easier.

The bottom of the unit has a ¼” – 20 attachment to facilitate use on normal camera tripods and clamping mounts.

The unit projects two perpendicular red laser lines. They are easy to see, even in highly lit areas, although outside during a bright sunny day may be difficult. The lines project up to 30’ away.

The Bosch MM 2 multi-mount is included. It allows mounting on surfaces from ½” to 2-1/4” thick.  Bosch also offers a magnetic mount.

I found the Bosch GLL 30 Cross Line Laser Level incredibly easy to use. You simply switch it on and arrange it so the lines are where you want them. That is it.

The laser blinks when it is out of plumb or level. This makes it easy to indicate you need to move it slightly so it can align itself. The “manual mode” that Bosch speaks of, is simply moving the unit to the angle you need and you’re all set. The only issue with this, is that the laser still blinks the whole time. While the laser stays on for approx. 3 seconds and is off for about 1 second, this is still a bit annoying. Granted, the vast majority of the time you will be needing a perfectly level or plumb line. That one time when you need to project a 45? it may get bothersome.

While the included mount is very versatile and easy to set up. Getting the final adjustments on the MM 2 can be touchy. I do not think this is any more difficult than using a tripod, or any number of easily available compatible mounts. They all rely on manually moving the unit to its final position. If there were a mount whose position was set by moving set screws as opposed to friction balls, it would make small, precise adjustments a bit easier. This would in turn add complexity and cost to the mount. Overall, this system is excellent for the intended market, weekend warriors and Do-It-Yourself projects around the house.

The literature states the accuracy to be 5/16” at 33’ (other models are rated at 1/8” at up to 100’ but at three times the cost). I checked this model against a known accurate bubble level.  The level line was spot on. The plumb line was about 1/16” off. Well within the stated accuracy limits.

Home Depot offers this model for $79.97. With other models costing as much as $250 or more, this price is a great bargain. Even though a level, plumb bob, chalk line, and marking implement would still cost less. The amount of time and headache this one tool saves seems well worth the price.

Bosch Cross Line Laser Level Review Final Thought

Overall, I was quite impressed with this little unit. It is easy to use, rather simple to set up, and very affordable. While I had no previous experience with this type of tool, I am sure it will be used often. My wife could have used this when she was hanging pictures a few weeks ago.
