The Bosch GLL 30 is a new line of Bosch laser tools out on the market. Bosch has been making laser tools for quite a long time, both in the laser-leveling and distance/range-finding market but the GLL 30 is quite a handy little device. It’s very small, easy to carry, and comes with a carrying case.
Upon receiving the Bosch GLL 30 professional laser level tool, I noticed it came directly out of the package with the laser, a set of batteries, a warranty manual, a safety instruction booklet, a nylon carrying case, and a mounting device that has a ¼” x 20 threaded seat. You can use the swiveling arm and clamp to mount the level it to 2x4’s, countertops, whatever. If you don’t have a tripod, you can measure up a wall, draw a line up at 48”, and stick this thing on the stud, giving you a platform to use as a baseline for all your measurements.
This laser level comes with an on/off button so there’s no need to have a locking/unlocking position. There’s a threaded hole on the bottom of the laser that will adapt with most tripods. Even if you have a camera tripod, this will fit on it. So you can set this in the middle of a room, turn it on, it auto levels and projects a horizontal and vertical level line up to 30 ft away. It gives you a big +. If you’re in a hallway and you’re 30 ft away from the end of the hallway, this will project on all the walls all the way down the hallway. So it’s a very handy tool to have if you’re hanging and leveling lights, pictures, whatever. I can see myself using this when I’m in the rough-in stage of an electrical construction project, where I could put this on a tripod in the middle of the room, turn it on, and have an accurate horizontal laser line across all of the studs. Instead of having to go around and mark each stud individually, I could use this laser line and hang all my boxes off of it. That way on my trim-out all of my plugs, boxes, switches, etc., are perfectly level with each other throughout the room. It’s a potential time saver and is extremely accurate as it has its own self-leveling mechanism on the inside. There’s no way to have this thing crooked.
As far as tech specs, the literature on this tool says it has a working range of 10ft or 3m. The working range can be decreased by environmental conditions such as direct sunlight. One thing I’m finding with all of these lasers is that when you get into sunlight you have a whole bunch of lights turned on in a house, it’s a lot harder to see the laser. But I think that’s just because of the type of lasers all these companies are using. The leveling accuracy is within +/- 5/16” at 30ft. The self-leveling range is typically +/- 4° so it’s not going to self-level if you get it outside of 4° from level – it’ll just sit and blink at you for a while. Operating temp it says you should keep it b/n 41° F and 104°F or 5°C to 40°C. It’s a class 2 635 nanometer laser that uses less than 1 mW. The threading for the mount is a ¼” x 20 – a pretty standard thread size. Even you had to rig something up on the job and you’ve got some ¼” 20’s in your truck you could use that to mount to the bottom of the level. And for those that don’t know ¼” x 20 means that the bolt thread is ¼” around and there’s 20 threads per inch. It uses 2 AA batteries, so it needs 1.5V to operate. The approximate battery life with 2 alkaline AA’s is a little under 10 hours (I’ll be testing this to gauge actual battery life). The measurements of the device are 2.8” by 2.2” by 2.8” and it’s extremely light, only ½ lb.
This is a very neat tool to carry around with you. If you’re a designer or a decorator and you’re hanging a lot of pictures, home décor, etc., this would be great thing to project a baseline on a wall so you can either take measurements off that line throughout the room. Plus, if you have a bunch of things in a row to hang on a wall, you can just project this line and use that. The laser seems very strong up to 30ft. Beyond that it’s a little weak. For me and my trade, there are some other Bosch lasers that I prefer – they’re a little bigger and you get more distance out of them, a little bit better functionality. I think they did a great job with this laser. I would give this tool a 4.5/5 stars. It doesn’t quite blow my mind, there’s a little more they could do. I know it’s a leveling tool so it doesn’t need to project out to the sides, top, and back, but I think that feature would be super badass because it’s so small. I love how compact it is, the other lasers I have are much bigger, but they do offer better functionality. They have a dot that comes directly from the top of the laser, so it projects a dot up on the ceiling. The bigger laser levels also project lines from the top, back, and sides, where this one only projects out of the front. That’s the only reason I’m not giving it 5/5, otherwise this is a very good tool, I love having this in my tool bag. The only reason I don’t give it a 5 is because I already have a bigger Bosch laser level that I like better.
