Bosch 300 ft. Self-Leveling Green 360-Degree Laser Level – Self-leveling Laser levels are one of ...
Bosch 300 ft. Self-Leveling Green 360-Degree Laser Level – Self-leveling Laser levels are one of the best tools invented for installing cabinets, windows, wall tile, doors and dozens of other uses. Over the years I have owned several red lasers, some 3-plane, and always thought they were fine and always got the job done. My biggest complaint was that they never worked very well outside; hard to see in daylight.
This is the first green laser I have owned and it’s a nice tool. It is advertised as 4x brighter than red lasers and after testing with a Bosch red laser level indoors, it is definitely brighter, but outdoors the green and red are about the same and become indistinct at about 10 feet from the target.
Regardless of its outdoor capability, I still like this laser, particularly for its brightness when used inside and for the audible signal it emits along with flashing, if the auto-leveling is out of range and your laser lines are not level or plumb. It’s a three-plane level and comes with a mounting bracket, a laser target card and a nice case for safely storing and transporting the laser and accessories. It uses standard AA alkaline batteries.
I mounted mine on a rolling tripod and so far, have used it to install interior doors and kitchen cabinets.
This is a well-designed, high quality, bright laser level. The three lasers make it very convenie...
This is a well-designed, high quality, bright laser level.
The three lasers make it very convenient to project lines along floors, walls, and ceilings simultaneously. While I don't typically need to use all 3 lasers simultaneously, I do often have the need to use 2 lasers at the same time, and it is convenient to be able to use any 2 of the 3--whether it’s the two vertical lasers, or one vertical and one horizontal.
The 360 degree lasers make it so much easier to position the laser level in a room. You can place it in the center of the room and the lasers will project around the entire room, unlike a 180 degree model where you may have to place the laser against one wall or in a corner to get good coverage. And the 360 degree lasers make it very easy to put the laser level at any height--whether on the floor, on a tripod, or mounted on a surface.
The large mount included with his laser level is very good. One feature that I really like is the knob that provides fine control for the vertical height of the laser. So if you are hanging cabinets or installing shelves along a wall, you can use the mount to carefully adjust the horizontal laser height without having to adjust a tripod up and down. One small thing I don't like about this particular laser mount is that the rotating portion of the mount can't be locked or tightened down. It swivels very freely, so if you bump the tripod or mount or laser, it the laser will rotate and cause the vertical lasers to move.
This laser level uses four AA batteries and has a fairly well designed battery cover that seems like it will hold up to some abuse. The level can also make a beep sound if the laser is positioned so that the lasers aren't properly leveled--a feature that can be turned off.
When placed directly on the floor, the horizontal laser is 5" above the floor, so if you have to do work involving things close to the ground, that might be a limitation in some cases.
While this green laser is generally very bright and highly visible indoors, it can be very difficult to see outdoors. If you need a laser for outside use, the beam becomes very difficult to see past about 10 feet, at which point you will need to use the included laser card, or purchase the optional laser detector unit. The brightness of the laser varies dramatically depending on the surface it hits, so a dark textured surface (stucco) may make it more difficult to see the beam compared to a smooth bright white wall.

This laser system will take your home remodeling to the next level like nothing else will. It is a fantastic addition to my toolbox for aligning anything. Just set it on the floor or counter and flip the switch and it draws a perfectly level line on the wall! See the picture below for an example of us hanging shelves. This model in particular is awesome because it has 3 dimensions of lasers, meaning you can line up much more complicated projects using just this tool (think of mounting a corner wall of cabinets).

The Bosch 300 ft. Self-Leveling Green 360-Degree Laser Level is a great level or laser transit. It makes a 2 man job into a 1 man job, allowing horizontal leveling of door frames, wallpaper, and other plumb tasks. It works on my Stabila tripod and should work on any tripod. It has two plumb lines at 90 degrees to each other. The green laser light reaches further than any red laser light and is much easier to see.

This BOSCH 300 FT. SELF-LEVELING GREEN 360-DEGREE LASER LEVEL is a fantastic tool. I am a painting contractor so I wouldn't be using this for construction purposes. I use it for when I have to paint a stripe on a wall it gives me a perfect level line to work off of . I wish I had it when I did the line in the pic below. I can do horizontal line as well as vertical lines. I like the green laser better than red ones it is much easier to see. It come with a mount that you can use on a table or on the ground. The unit itself has self leveling capability which is great. you can purchase a pole or a tripod to mount it on. Luckily I have an old camera tripod that works great or I have pole for a dust wall that also works great. There are many other features. Overall this is a very high quality tool and I recommend it.

I have wanted a laser level like this for some time to help me with some of my trim and other remodelling projects. I also wanted to use it specifically to help build a deck. This laser level is extremely easy to use. Simply set it down and turn it on it will actually self level itself so that all you need to do is adjust the height. It has a nice bracket that allows it to attach him to multiple types of material so that it can stay firmly in place while it gives off its bright green laser light multiple planes of 360゚ green light. The green light makes it very easy to see And although I did not measure specifically, the light does cast for a very long distance. All of the pieces come together in a nice hard plastics case to make it easy to store and transport. Overall it seems to be very well constructed of quality materials and with care should last me a very long time period very pleased with this excellent accurate and time saving tool.

This is a very very impressive laser level! I love all the functions it comes with and the extra mount (BM-1) that helps with multi-surfaces. The set comes with a nice padded bag to protect the laser and a hardset box for easy carriage. The 3-planes are at 90 degree angles and can be toggled with the "laser" button for different options. I think it would be great for installing grid-patterned recess lights.
The light is super clear even throughout the whole floor of my house. It will be perfect for a new construction project in leveling the floors or ceilings. During my renovation, I remember spending extra time with another laser, but this wouldve made it much easier, since it self-adjusts up to 4 degrees. The only thing i didnt like is that it lets out a loud alarming beeping sound when it is not level. Say, if you were trying to do a handrail, it will be beeping the entire time. I havent found a way to fix that yet.
The mount has several functions - clamp tool, height adjustment, and magnetic backing. I think the height adjustment is great for ceilings because you can place the mount about an inch to the ceiling and slowly adjust it to as close as you need - much easier than trying to get it straight as you bump the ceiling. Overall, i think it is pretty functional. FYI, it uses 4 AA batteries.

Well best we can do here is an average rating as a tool is only as good as it's weakest part - in this case the BM-1 Positioning Device. So we took it to the job site, mounted to to the structure and set our horizontal laser line (21', marking the line), using a vertical laser line we moved across the project. when we got to the end there was a 1/4 inch drop in the line, going back to the device and laser we rotated it from there checking the marks and the closet marks were off the same. going farther we found the mount on the BM-1 was not at all solid and the whole laser was tipping as it rotated as the weight moved. The laser line itself was true, just that the tilt allowed the whole laser to rock, lowering the level. We set a second tri-laser up at the other end to verify and the two lines matched true, so weakest link - Positing device. I also already have a BM-1, so viewing the two next to each other - verified the loose mount. The GLL3-300G 360° 3-Plane Line Laser is a very good level and alignment tool, but a bit short on battery life being listed as 4 hours with all the laser on. In bright sun light we needed the targeting, but this is normal and I have the green glasses that improve the lines visibility.
Now for those who thinking on this - we use a tri laser to build a 14x58' awning and setting fixed points to mount and remount as needed, there's a 1/6 inch difference from one end to the other and we are Sq. Set up and planning, plus checking will save hours of going back and a good laser level is a must, be it a small in home hanging of pictures right down to building a new garage.
I recommend this product (Laser) but are disappointed in the Positioning Device.

I was hoping to get an easy to use accurate laser level to do layout work with. What I got was an easy to use accurate laser level with the high quality I expect from Bosch tools. The level comes with it's own multi-adjustable mounting base that is well made and works well. This level is truly impressive and so easy to use. To use the level you simply install the supplied batteries mount it on the supplied base and turn it on. There is one safety rule, DO NOT LOOK DIRECTLY AT THE LASERS, you can look at the lines they generate but not the lasers themselves. The level can be mounted for use either on it's own base or the level and base can be mounted on a user supplied tripod. The level generates lines on three planes and the only thing the user needs to do is to make sure that the level itself is mounted within 4 degrees of level and plumb. The level will correct itself within that range giving you three bright level lines to do your work. The level also comes with it's own carry case. This level is an instance of you getting the quality and accuracy you pay for. It comes with a three year warranty as well.

I’ll definitely be using a lot less chalk lines and marks for a lot of different projects. I used it to install some shelves and some cabinets already and it works great. I can’t wait to get the Bosch stand for it because I think it definitely will work better with the stand. This laser is perfect for anyone that works in the remodeling business or flooring or anything that requires some straight edges. I own the smaller single Bosch laser but this is definitely the pro up grade I needed. The green laser is very visible and that’s definitely my favorite thing about it. Outside it’s a little tougher to see it but in a well lit room its highly visible. I checked the laser lines for square and level just to make sure and it was spot on.gery accurate. I also really like how I can find tune it because it has a up and down adjustment knob and extendable legs for balance. Also a lock to keep a position and a just laser line feature for different projects. It came with a carry case and a pouch for the actual laser to protect it well. It’s really easy to use and doesn’t have a bunch of confusing buttons. It even warns me if I have to adjust if it’s moved to much and starts to beep. The adjustable mount is really nice and can be fine tuned and can also be mounted magnetically. For me as a remodeler it’s a must have that is a game changer. I wish I would’ve gotten the 3 laser sooner. It’s definitely the way to go and i think any pro would love it.
