50 ft. Cross Line Laser Level Self Leveling with VisiMax Technology, L-Bracket Adjustable Mount and Hard Carrying Case

Unfortunately the self leveling function in both the vertical and horizontal planes is pretty bad. Both on the ground and the bosch tripod (with manual leveling of the unit itself), the laser is inches off. I tried in pitch black as well with all curtains closed with the unfortunate same result. I was quite excited bought this unit along with the bosch tripod, hoping to create clear edging lines for painting on walls/ceilings. Unfortunately this doesn't seem to work at least in my environment.

Another great tool from Bosch. Works awesome for my tile work! Great price makes it even better!

I bought this line level to do a kitchen. Mainly to hang the cabinets. It worked wVery well. The only draw back is the storage bag is to small to accommodate the all of the accessories. I we’ll be using this on future jobs around the house. Overall this is a solid product. Bosch does it again!

Works great, easy to mount to tripod or other objects. Easily repeatable readings, gyro lock keeps everything safe while it is in the storage case.

Great product. Made framing walls easy for a first timer.

Simple to use Outstanding for tiling projects Very bright laser beam is easy to see in any light Solidly built ON/OFF switch would be better if it were a finger sensor button so you don't jiggle & move the focal point when you turn it off

The Bosch GLL50 self leveling laser level is a great tool to have. As the name states it is self leveling, and it blinks when it is out of its range, meaning when it can't self level. With an accuracy of 1/8" at 33 ft it can be used across larger rooms and still be very accurate. The self leveling can also be locked so that one can project a line that is at an angle. The set comes with a holder which makes it easy to clamp it to something and then fine adjust the position with the hand wheel. It also comes with a target which makes it easier to see the laser in daylight . The set also comes with a belt pouch for the laser level..

These types of tools have been out many years so the concept of them is not that new. I have never purchased one for my personal tools ant home but do use the company's on the job site quite a bit. Its a different brand and a whole lot more expensive. Its used in all aspects of construction from general carpentry to steel building construction. This model is a more user friendly compact type to be used in a bit smaller scale of job but can to all the same things within 50ft. Where this tool shines is in the home. we have used it in one month to layout and install kitchen cabinets, hang picture and photos on the walls, paint perfect boarders and stripes on the walls in the kids rooms, hang shelves in the bathroom and basement and list goes on. the self level feature is spot on, use may even discover your ceilings or wall being out of level which is good so you know not to use them as reference base points anymore. We had to layout a polka dot grid pattern in my daughters room and without this tool wouldn't have been able to accomplish it in the time we did and that's the room with the out of level wall and ceiling, but with this its perfectly laid out. Here are a few tips when you get it. .1 purchase the tripod along with it. so convenient and easy to make adjustments and setup anywhere. .2 when using it try not to put it in your immediate work space if you not on a concrete floor. if its on a sub floor, when you walk the laser with pick up the bounce in the floor and project that onto the wall. .3 always make sure you on the right setting cause the laser lock and auto level can look the same at first but be slightly of. 4. and lastly....Have fun with it and be creative with your projects. Friends and family are always amazed how straight and level we have things.

The 50 ft. Self-Leveling cross-line laser is great. The tool is built very solid, and comes with a stand for sitting it on the floor as well as mounting it to a tripod if you need it higher. The laser are very easy to see, and once you place the tool it levels itself quickly. It comes with a case as well for the tool to help protect it while not in use. This tool will come in handy when I need to hang things on walls so I can have them perfectly level while I am doing my work. This will just simplify my jobs so much. It works great and I tested it on various corners of my house, and it shows all of them to be square and straight (which is good). I am really enjoying this tool, and look forward to the many years it is bound to bring me.

This is an incredibly simple-to-use laser measure and positioning device. It used to be quite difficult to put up a new wall, or position a new window perfectly straight and level. It required a long processes of using hand held levels and trial and error until you got it right. With this tool it is very easy to ensure straight and level installs every time. Building anything that requires everything be absolutely straight and level is now much easier with this device. The Bosch GLL 50 has a self leveling function that that uses a smart pendulum leveling system and is as easy as turning it on and waiting a couple of seconds for it to self-level. The cross laser beams are perfectly perpendicular to give horizontal and vertical accuracy at the same time. I have used other laser leveling devises over the years that were crazy expensive and took hours to set up. This one is moderately priced and all you have to do is turn it on and start putting up walls. It comes with several options for placing it wherever it is needed to get the job done. You can just set it on the floor, you can attach it to existing structures with the clamp or magnets or temporarily screw it into a wall. You can use a camera tripod because it is very light (the tool only is right at one pound). You can attach the magnetic rotating mount to any ferrous metal object. It has a micro adjustable height positioning mechanism built in, so once it is securely placed, you can use the micro adjustment knob to get it to the exact height you need. You can use either the horizontal beam, the vertical beam or both. You can also choose between using the self level or locked positions. When in self leveling mode, the beams will flash on and off for a couple of seconds while it's leveling itself. After a couple of second the flashing stops and you know it is level and ready to go. It also has a target plate that improves visibility in for when in bright outdoor light. There is a vertical reflective strip on it to ensure you have everything perfectly lined up. It even has it's own protective pouch to keep it in when not in use. This tool is quite rugged. You wouldn't want to throw it down or let the tripod tip over, but normal usage won't harm the sensitive leveling mechanism.
