Bosch Laser level, GPL5S. (SKU 1000010441) from Home Depot. This product was supplied by Home Depot through the SEEDs evaluation program.The Laser level is about 4.0 inches long, and about 1.6 inch wide, and 3.0 inch high. The level with batteries weights about 8.8 oz. (Without the adapter base attached) The laser level is powered by three AA batteries, comes with a carrying case that will fasten to a belt for carrying. There is also a mounting base that screws onto the base of the Laser level. The mounting base is a adapter, that has magnets, and slots for a mounting strap. This adapter can be used to attach the level to different surfaces for setting up a reference beams. They also supply a target plate for in spotting any of the five beams. The Laser level projects five beams, covering three planes, X,Y, and Z. There is a slide switch that turns on the laser, as well as locks the beam mirror optics from moving when in the off position. On the bottom side there is a threaded hole for a 1/4-20 screw, so that the level can be used with a standard camera tripod. The laser level is designed to be “self-leveling”, that is the five beams are projected from a reflector assembly that is suspended inside the laser housing like a pendulum. The Bosch laser level carries a two year Warranty.The level is designed to be used as a reference for construction projects. When installing walls and partitions, or any object that needs to be level, square to another object, or perpendicular to floor plane. I have used these levels for installing cabinets, and shelves, and for aligning pictures on a wall.The user manual goes into detail about how to check the calibration of the level, and how to adjust it if needed. I haven’t seen this type of detail in other product manuals, nice of Bosch to include this information. I did run a quick check of the calibration based on the information in the manual, and found this unit to be calibrated right on. The level seems to perform quite well. The only thing that I found amiss, was the adapter base that comes with the laser level. The one I received was not flat on the bottom, so if it was attached to the laser level, and placed on a flat surface, the whole level would “wobble” like a chair with one leg too short. Investigating this, revealed that the adapter was constructed of two plastic halves, that when assembled, they did not line up flush on the bottom and top sides. This produced a offset at one end of the assembly.The “bottom” of the laser level assembly without the adapter attached was fine.Observations; The easiest way to make use of these type of levels is to use them with a tripod. There are 1/4-20 threaded mounting holes in both the level assembly, and the adapter attachment, which attaches to the base of the laser with a 1/4-20 screw. In use, the laser beam spot does diverge as the distance from the level increases. At about 35 feet I noted a beam spot size of about 1/2 inch. If projected out to a 100 feet this would probably be about 1.5 inches. I would have liked to have seen a smaller beam spot, no more than 1/2 at 100 feet. In cases like this, you would have to estimate the center of the beam for your measurements. The manual spec’s the maximum calibration deviation to be 9/16” at 78 feet from the laser. So, if your beam spot is as large at the calibration limits, there is some question as to what the real accuracy is. In actual use, I would suggest that the center of the spot would be the most accurate to measure to. Better collimation of the laser beam would help.As with any alignment laser tool, when used under brightly lit conditions the laser beam, or spot is very hard to see. To aid with using this this level under these conditions a target plate is included with the level. The target plate has magnets to allow it to be placed on steel framing studs or other metallic locations. This would be handy in aligning metal stud partitions. There is also a strap that is included to be used with the adapter base, so that the laser could be mounted on odd shaped objects, such as pipes, or wood posts.Except for the two items I noted above, the laser level seems to perform quite well. I hope this information is helpful.

I keep my Bosch – GPL5 with me all times. Im not only a regular construction employee. Also once we finish build we also help our costumers hanging ther pictures or design plates on dinning room master wall. Easy to carry on my backpack is with me 24/7. Also it is easy readable out doors at the time to level the ground on a manhattan townhouse backyard.

There are two main types of automatic laser levels, those like this that send out reference dots and those that paint lines for level. I have an use both. This type is used for instances where you might us an old string plumb bob in the past. It is also much easier than measuring and doing the 3-4-5 calculation for right triangle verification.I have had two recent uses for it and found it made things much faster and nicer than doing it the old way.First, I have been replacing posts on a front porch. I’m setting post holders in concrete. I can use the magnetic base of this tool to hold to the galvanized steel post holders and directly line up the holder under the previous post position. I wish this model also had laser assembly lock, as that would then give me a line perpendicular to the post holder flat and allow me to quickly set level as well. That is the only downfall of this model I could find.When placing posts or other construction that requires square alignment over a decent distance, this was amazingly easy. Setup so the dot is just scrubbing the edge of two posts and then you can just hit the edge of the other post with a 90 degree angle beam. This made doing much of my recent construction solo actually possible.If I was in a situation to purchase a tool like this, the only reservation I would have to this model is lack of lock. But it will get plenty of use in my tool box.

Bought as a backup to my PLS5. It was dialed in straight out of the box. Do wish it came with a more substantial case to protect the unit. Overall pretty good value for the price

Misleading it doesn’t come with the soft case or target shown in the photo. There is a place for them in the case, yet it is empty. Without the target it is hard to be accurate when laying out deck piers or layout and leveling off a house. Also the soft case would be useful…

Someone put a lot of though into the “multi-purpose attachment” for this laser. It will let you mount using most tripods. It has magnets to let you use the side or top of metal equipment or structural supports. It has screw holes with a spacer to let you mount to drywall or wood. You can also strap it to a pipe, or similar sized material, with strap slots for both vertical and horizontal mounting.The laser itself works well for laying out walls, determining height, and plumbing up/down. It has a beam on all axises, except going out the back. (The battery compartments prevents going in that direction.) With each beam at 90 degrees from the next, it is great for laying out corners.Another nice feature is that the laser runs on 3 AA batteries. So there are no expensive batteries to keep around as spares The beam will flash slowly when you have less then 8 hours of battery life left..About the only down side to this laser is that it isn’t really bright enough to use outdoors. It is almost impossible to see where the beams hit is bright sunlight. This is unfortunate, as I was hoping to use it to lay out the base for my new shed. But it is doing a good job of helping me lay out my workshop walls.As long as you are close to level, the laser will level itself for you. It flashes if it is more then 5 degrees off level.

Previous reviewer is right, the beams are not the brightest you can find. I have seen a bunch of different point lasers over the years and there are some out there that will give you a better laser dot for sure. But they’re still plenty bright and I love this one because it’s so small I can carry it with me at all times and that to me matters more. I also like the fact that it locks when you switch it off, they say it will help it keep its accuracy over time. All in all an excellent tool, I have used point lasers for a while, saves me from doing all those 3-4-5.

have purchased multiple units for my company and have had the base come apart from the unit because the nut is recessed in the plastic and over a period of time it pulls free and there is no way to reattach
