GLM100-23 100 Ft Blaze Laser Distance Measure, Includes 2 AA Batteries

This laser distance measurement tool made my renovation planning so much easier. Instead of juggling a tape measure (and needing a second person to hold the other end), I was able to measure rooms, walls, windows, and even ceiling heights quickly and accurately on my own. The readings are fast and precise, which gave me confidence when ordering materials and planning layouts. It saved me so much time — especially when mapping out multiple rooms and double-checking measurements. It’s lightweight, easy to use, and the display is clear and simple to read. I love that I can just point, click, and instantly get an exact measurement without any hassle. If you’re remodeling, redecorating, or even just planning furniture placement, this tool is a total game-changer. It made the entire process smoother and way less stressful. Highly recommend!

First laser tape measure and I love it. Very easy to use and it has been very accurate so far. I had to take out and replace the batteries a couple of times to get it working at first. It seemed to freeze up a couple of times, but now works perfectly. I'd recommend getting it if you are shopping for a device like this.

I’ve used the BOSCH GLM100-23 100 Ft. on almost every job and site survey for a long time now, and it’s been nothing but dependable. The battery has never given me any trouble, and the grip feels solid and comfortable in my hand. Measurements are quick and accurate, which makes my workflow smooth—I can measure, jot down the numbers, and move on without wasting time. It’s become one of those tools I don’t even think twice about bringing along because I know it’ll perform every time.

Works perfectly. Extremely handy when you’re up on a ladder . Super accurate 👍 You won’t be disappointed.

Compact and accurate yet often difficult but not impossible to aim laser precisely when pointing upwards. I used it for installing multiple pipe hangers at different elevations. It is a good tool to have.

I used this for quick wall-to-wall and floor-to-ceiling checks while creating a gallery wall in my living room. It was easy to hold, and the measurement showed up right away after pressing the button. The screen was easy to read, and the small beep helped confirm the reading was captured. Just to be extra careful, I checked a few measurements against my tape measure, and they matched what I had marked. It came ready to use with the included AA batteries and continued to work consistently for basic indoor measuring.

I use this laser measure for architectural surveying to create asbuilt floor and ceiling plans. I work alone and use a laser measure and a sturdy 25' measuring tape. For 10 years I had been using a very premium but heavy bricked sized Leica measuring laser, until I met a contractor in the field who had a pocket sized laser like this. I was surprised at how small they were, and in the last couple years, how affordable they were. So I made the jump and purchased a different laser from this one two years ago. However, its battery life was a little sporadic, there were a lot of features I didn’t need, and it could only measure to a 1/16 of an inch, which is more than I need. You could also change the reference point of where the laser measures from (moving it from the rear of the laser to the front). This is not helpful when you can change it without realizing it. So recently I was researching newer lasers, since I was not satisfied and I found this GLM100-23. I spent time comparing it to some of the more expensive Bosch lasers, like the one with the green beam, but eventually decided this one. I measured with it yesterday and was so pleased with it. I love the fact you can adjust the fraction amount to what you need – gone was my mental math to assign a decimal value to 1/16ths of an inch (its faster to write down the decimal than the fraction). The screen showed one measurement at a time, but was so legible! The other laser had a screen that would time out and then it became hard to read. This laser has white numbers against a black screen that doesn’t time out! The laser is so small and lightweight, you can easily hold it and the tablet at the same time. Lastly, the reference point for the laser can’t change, so there’s no way to fudge up the measurements you need. Overall this laser is EXACTLY what I needed. Also, a note: the "click wheel" is an internally displayed menu that allows you to change the measurement option (from feet, to inches, to centimeters, to millimeters, and then feet as displayed 0'-00"). You access it by long pressing the fraction button.

This is the coolest tool in my tool bet! I love this measuring laser! Just point and click and you'll know instantly know the distance in whatever metrix you are using

The BOSCH GLM100-23 has been excellent so far. The accuracy is spot-on, the measurements are consistent, and the backlit display makes it super easy to read even in darker rooms. Setup is simple, and the interface is very user-friendly—perfect for quick measurements or more detailed work. The build quality feels solid and professional, and the 100 ft range is more than enough for condo, townhouse, and indoor use. It’s lightweight, fits well in the hand, and the response time is fast. Overall, a very reliable laser measure that makes the job much easier. Highly recommended for anyone who works in real estate, construction, or needs precise measurements.

Great product

The good thing about this Bosch GLM 20 is that it’s compact and less complexed. For people who need Just 1 button to tell the distance.

Easy to use. Does exactly what it’s meant to.

It is a very useful for getting accurate length
