100 ft. Self Leveling Cross Line Laser with VisiMax Green Beam

The tool says extremely bright lines for outside use. Couldn’t see lines on lumber 12-15 feet away.

Not much better than my old GLL 2-15. And it is much larger. I bought it as an "upgrade" and I will bot be keeping it. Note the attached photo, taken on an overcast day in the building's shadow. The green laser is just barely visible, a bit better than the red laser. But still not usable outside. If you are using this indoors and do not mind the size and price, it is great.

Worked great, I used it to place sound dampening panels on a cieling . Worked as I hoped for.

I've got red self-leveling laser but in daylight it's hard to see the beam. I heard about this green laser and that it should be much more visible than the red one. I was very skeptical, to say the least, but I got it anyway to test if what they claim is true. In the attached photos you can clearly see that the green laser is more visible than the red one next to it. I'm impressed to see that for once the advertising is indeed true. The laser comes with a belt bag, batteries, a multifunctional clip, and target. The laser can be set to horizontal, vertical, or both. The self-leveling can be switched of, which is handy in some situations.

Laser levelers used to be two kinds: cheap/useless, and expensive/useful. Bosch may finally have created a laser that is reasonably priced and powerful enough to use in just about any residential application. (Most commercial applications, too.) Keep in mind that this is not a rotary laser, but it will self-level if you are patient and wait a few seconds. With a range of up to 100 ft, you're not going to lay out a road with it -- but a driveway? No problem. The beam is bright enough to be visible outside. Kitchen cabinets, framing, drywall, molding, pictures...the list of things that could use some assistance from this laser go on for a while. Thoughtful details include self-leveling (or the ability to choose not to self-level -- this allows you to lay out stair handrailings, for instance, at the proper angle), a clip for steel framing or suspended ceilings, an adjustable mount, and a target with retroreflective tape. I would suggest one minor change in the design, and that is to make the clamp able to clip onto 2x material (1.5" wide.) The clamp will only clamp onto material that is a max 1/4" thick. Also, I suggest making the packaging less like Fort Knox. That clamshell package was well sealed and required a knife to open.

I have a red beam cross line level (also Bosch) and it has served me well. But there are lighting situations where the red laser is more difficult to see thank the green laser. Usually it is difficult to see when the laser bean is cast onto a well lit surface or outside on a sunny day (neither one works well out in the bright sun). In most situations I have tried it in the green laser is easier to see and but it is not always as sharp. The red laser has an accuracy of 1/4" @ 100 ft this green on is 3/8" @ 100 ft, so I guess the green laser diverges more than the red. This could be from better optics in the red cross line laser lever or actually something to do with the wavelength of the red light compared to green light (I don't really know, it just looks sharper. See images in this review for yourself). Nice added features in this kit and the level itself are: -comes with a carrying/storage bag/case, it's only big enough to hold the level. -comes with a Bosch BM3 Magnetic Line and Point Lasers Positioning Device with Extendable Legs (amazingly versitile) -Laser can be locked in position so you can project lines that are perpendicular to each other but not level or plumb -Each lasers line can be turned on/off independently (Not super useful but I guess it could save some batter power) -comes with a target plate -come with batteries (3 AA) Reading the manual for the BM3 Magnetic Line and Point Lasers Positioning Device with Extendable Legs will be useful to figure out and understand all the ways that it can be used. When I first looked at it I thought it was kind of cheap and hokey looking. But after looking over the manual for it, it really is well thought out and amazing how many ways it can be used. I though it was just a little tripod and a magnetic mount but it can be used in so many more ways. It almost like a transformer that really never looks cool or like anything but it is very versatile. Having a regular tripod is also very useful for this level too, a lot handier than trying to stack stuff to get it to the height you want.

I reviewed a similar Bosch model a few months ago, it was the standard red laser and its was great then (see my previous review). This version with the green laser is amazing, the green laser is so intense full daylight of dim room (see pics). The form and function is the same as the previous models aside from the green lasers distance its able to cover and visual improvement. It still comes with a multi function mount that can be a surface mount, wall hung mount or l-channel drop ceiling mount. It also comes with carrying case and laser filter/marker lens. It addition to a self leveling cross line it also has a button to turn of the vertical line as well as a lock function to be able to rotate the cross line. The uses are endless for for a piece of equipment like this. I find it best used with a tripod. Its has a standard camera screw in mount and a larger heavy duty surveyors screw in mount. If you have a standard red laser model it might not be worth the upgrade but if you do not have one yet then this one would be the version I get.

Finally a vertical and horizontal laser with auto level for the diy enthusiast in your home. The green laser light is so much clearer to see and with laser enhanced glasses even more so. Remember never look into or point the laser beam into someone else's eyes. This unit comes with a handy heavy duty fabric case that protects the laser unit from job site dirt dust and drops. There is a handy multi application hanger that comes in kit along with a alignment guide. This unit will project a beam in multi configurations and can be mounted on tripod or hung on metal or clipped to ceiling panel runs or placed on floor. Against the wall the unit projects a 360 beam around a room. Easy to set up unit just put in included batteries into easy to reach compartment and turn on and set your application. Comes in blister pack security packaging.

This Bosch GLL 100GX laser level is a easy to carry, affordable, battery operated, self-leveling, green cross-line laser level and perfect for the homeowner. The bracket adapts to either a camera tripod using standard 1/4-inch camera mounting threads. The same bracket also clamps or adhere's to metal surfaces with it's own built-in super strong rare earth magnets. Soft carry pouch is included with this level making it a complete kit however I would have preferred a hard impact carrying case. This deficiency is remedied, however, by purchasing a Pelican case which I highly suggest you do since this is a precision leveling tool. If you have any projects requiring use of a laser level this cross line level will enable you to complete your projects quickly with professional results each time. Hanging kitchen cabinets is no longer a detailed task because this level is self leveling making it a joy to snap chalk lines. Battery life is excellent. Be sure and remove batteries after use as you do not want to ruin this precision level should corrosive batteries leak. The tool will pay for itself after your first kitchen remodel project. A whole lot of thought went into this Bosch level one of which is a fine vertical adjustment knob on the bracket making it easier to fine adjust your horizontal laser line versus having to "bump" the magnets. When powered off the pendulum locks which is important since you don't risk damaging the actual laser head.

Easy to use and very bright beams. I would definitely recommend this to people.
