Does this laser have slope capability

Can it be set to match the slope where a fence is going? I would like to use this outside to line up my fence both vertically and horizontally. The ground has a slope so fence has to match that horizontally..
Asked by: Fenster
You can lock the laser and adjust it to an angle.

Can you tilt it up higher and have it self level?

I used another level that you could tilt up on a tripod and it would self level at the height you pointed it at for a vertical line. I just bought this one and it seems you have to have it at the height you want the laser line to be. When I tilt it up it blinks, which means it is beyond its capability I guess...
Asked by: Stevo
It self levels only so far. You can tilt it but only to a certain degree.

Self-Leveling Long-Range Cross-Line Laser Level is rated 4.1 out of 5 by 35.
Rated 5 out of 5 by from Impressive Laser The coverage of the laser is amazing. If you set it up on one wall it projects a line that almost entirely covers the other three walls. The beam is really bright making it easy to see and if you don't have the laser in the acceptable level range it pulses on and off to warn you. It projects a horizontal and vertical line at the same time or projects the two lines individually. This device is ideal for installing moldings, pictures and cabinets for the home owner. It has endless uses for construction with its long range capabilities. I recommend this laser and also suggest getting a tripod for it. It makes using it much easier.

Rated 1 out of 5 by from Cheap mount Laser works fine but the magnets fall out of the mount constantly. Once both magnets are lost you are left with a perfectly good but uselesslevel.

Rated 2 out of 5 by from NOT FOR DAYLIGHT USE Purchased this laser thinking it would be clear at 15 ft. IT IS NOT. It was outside and was in the daylight but mostly in a shady area. The machine was not visible at even 7 to 8 ft. It is for interior use only and not usable outside at all. They say up to 150 ft but I would not trust that to be accurate even inside.

Rated 5 out of 5 by from Works great I bought this product because I had 6 pre-hung doors to install. Using levels it used to take me ~30 to install a door. Using this self-leveling laser I was able to install a door ~10 minutes. This product will pay for itself in only a few jobs.

Rated 2 out of 5 by from Not for outdoors Bought this one because it's for "Outdoor Use". I have a cat toy laser brighter than this...cloudy day, could not see lines beyond a foot. Works great indoors.

Rated 2 out of 5 by from Returning Today This is useless outdoors unless it is almost dark. Directions are just as useless.

Rated 5 out of 5 by from Built like a tank. Self leveling is such a luxury! If you can afford all the bells and whistles you'll probably end up with a rotary level. If you're looking for a good price point for a tool you don't plan use often, it can be hard to justify a rotary. I actually own an inexpensive rotary and worked with it quite a bit when restoring my barn. The nightmare of that tool is that it's not self leveling. I wasted a lot of time leveling and re-leveling it during that project. In fact, I had to tread as if on egg shells after leveling it to get to the walls to transfer the lines because of the bounce and movement in the loft itself. While this laser isn't a rotary, because of the self leveling feature it's easy to simply rotate it in place to extend the line if need be. I did just this on a patio project that I'm currently working on. I installed two granite steps in front of the barn and mudroom, leveled to lines I set with the laser. My next task was to scribe a second line for the patio itself. My driveway slopes up to the barn. I ripped out the pavement at the top and will be installing a level granite block patio that encases those two steps. This means I needed to scribe a level line against the house, the barn and across the two steps. I will build up to that line. My first challenge with this level was the lack of a low, adjustable tripod. The laser comes with a small tripod, which is adjustable (quite nicely, I must say!) only when hanging by the clip, which is meant for drop ceilings or when using the magnetic mount. When the two arms are swiveled out to form the sitting tripod, you can't adjust it vertically because the arms are attached to the riser and lift right off the ground. As you can see in the photo this meant I had to go through a sloppy trial and error process of stacking scrap boards until I found a height that I liked. The next laser up is the GLL2-45, which includes the WM1 tripod, which looks PERFECT for my needs. The problem is the extra cost to move up to that model. I'm not sure what other differences there are between these two models, but I think you should compare them when making your choice. You can also buy the WM1 separately. It's expensive for such a small accessory, though. If I were a cabinet installer, I'd buy it for the bases, along with a regular tripod for the uppers. My next challenge was that there was no hope of seeing the laser outside during the daytime. I know I have a pair of red glasses that came with my other laser but I couldn't find them, so I was forced to wait until the evening to work with the laser. That was obviously less than ideal. I don't know whether the glasses would have worked in that sunlight, either. Bosch offers the LR30-RT laser receiver, which is a separate device that picks up the laser even when you can't see it. Unfortunately, it's more expensive than the laser itself! I do think they should include a cheap pair of red glasses with the level. My third and final challenge was that the unit has to be fairly close to level in order to operate. If it's not within 4 degrees of being level the lines flash, indicating that it's incapable of self leveling. I wish it could accept a wider range because I had to mess with shimming the stack of scrap wood , trying to get it to stop flashing. This wouldn't be a problem on a real tripod, but if you're doing any outside work, the ground is never level. This may not be a problem for you if your intended application is indoors on reasonably level surfaces. The unit itself is crazy rugged! I was quite impressed when I saw the bag and even more impressed when I removed the unit. It's a real tank, for sure! It's easy enough to operate and I have no complaints about its features or operations. It worked great on my above mentioned work, once I could see the beam. It took me all of ten minutes to get the desired line established and transferred. The "positioning device" (pseudo tripod) is really rugged. I'll never use the drop ceiling hanger, and probably won't use the magnet mount, either in my residential projects. That's a shame because the sliding mechanism is fantastic. It's got a firm, smooth movement that seems precise. That leaves the basic nonadjustable tripod mode for sitting it on something. I've read some complaints about the magnet not being strong enough, so if you intend to use that feature you might want to research that. Included is a "measurement plate". The instructions gave very little information on how to use it and I haven't figured it out yet. It's a small red square with a reflective backing on one half and measurement marks. I'll have to try to find better instructions or hopefully a video. I do recommend the laser, but I wish it were easier to compare the various models Bosch offers. I found it to be quite difficult to spot key differences that could help decide how much to spend. If you plan to use it on a tripod I think you'll be quite pleased with this level!
