Product Overview


The Bosch GLM 100 C Lithium-Ion 330 ft. Laser Distance and Angle Measurer with Bluetooth technology and app is the smart solution for transferring and documenting your measuring results. The new GLM 100 C Laser Distance and Angle Measurer transfers your measured values directly to a PC, tablet PC and Smartphone. Quickly and easily transfer files without errors via Bluetooth or micro-USB. Simply take a photo of the jobsite using the Bosch GLM 100 C measurement camera app and enter the distance you want to measure into the photo and perform the desired measurement to have it displayed directly in the picture. Take further measurements if necessary and send them by e-mail to coordinate them with other participants in the construction project. The measured values can be individually named in the measured value list and saved in special project folders with the date, time and type of measurement. Areas and volumes can be calculated by simply dragging the measured values on top of each other and all functions of the GLM 100 C can also be remotely controlled from the Smartphone or tablet, allowing users to make measurements in hard to reach spots or in short range, target-less applications. Another advantage of the innovative GLM 100 C from Bosch is the possibility to pull individual values together in one line with a tap of the finger. The app then automatically calculates the resulting distance, area or volume, taking into account whether it is a distance or area value. Moreover, professional trade users can file all the data from their different building projects in purpose-created folders and if required, send pictures in JPEG format and PDFs directly from the app. This enables people to also work together over great distances, allowing for precious time to be saved and the desired results achieved more quickly.
  • Bluetooth functionality conveniently transfers and stores measurements from the laser measurer to an iPhone, iPad or Android device via free app.
  • Precision measuring technology measures up to 330 ft. with up to 1/16 in. accuracy
  • Built-in tilt sensor displays 360 degree angle measurements in two axis, allowing for more accurate measurements
  • Backlit display with tilt-screen technology offers easy viewing in all directions
  • Optional R60 digital level attachment transforms the GLM100C into a 24 in. digital level (not included)

The smartest money I ever spent. My review can't ever do this tool justice. The bottom line is it is so convenient and makes everything easier. I used it all the time when I was house hunting. It works with an iPhone app so you can take pictures and add the dimensions it measures onto the photos. I used it all the time when I was comparing houses and getting estimates on needed work. The app with remote measuring and so many helpful features make this a time saving godsend. After I bought my house I used it all the time when I was building just about anything. It is very accurate and the laser dot helps you ensure you are measuring where you want to be measuring. I find myself reaching for this more often than my tape measurer.

Consistently accurate and more functionality
Primary use is to gather site measurements for construction document preparation on remodel projects. Using the free mobile device apps do away with the normal on site documentation of taking measurements in the field. Now you can use an iPad or iPhone's camera to photograph an area that needs to be measured, and then transfer measurements to the device to coincide with lines you add to the photo with the touch screen for all the area's measurements. Add the lines for measurements you want to take with the laser, tap a line on the screen photo, enter the measurement from the laser (directly when using the Bluetooth GLM Measurement & Document). Having the measurements and lines on the photo when you get back to the office to transfer to the CAD program means you are very unlikely to miss a measurement, or find your written notes not represent what you remember. You also have the photo of the area to refer to while transferring the information to the CAD program. Clear as a bell and the Bosch functions reliably and clearly. The offset measuring functions are something I never had on my two previous laser devices, so the field conditions do not get in the way of a needed measurement. The accuracy within a sixteenth is 50% better the the other models I've used. The greater range is great, particularly for outside measurements, and the audio signals let you know when the measurement has be taken without having to look at the screen. I am very happy, though the apps could use a little tweaking.

A must for every Realtor's Tool Kit!
We bought this for use in our residential Real Estate Brokerage. One can't even begin to describe how much easier, and faster, it is to measure a client's home using the Bosch GLM-100 devise. There's no comparison to alternate measuring methods, we've used them all. Tape measures are bulky, sonic devises are better, but not very accurate, laser is the way to go. We stepped up to the GLM-100 because it can interface with our "Smart" devices which allows for a quick tally of rooms measured. To be honest, we're still learning all the things we can do with the communications interface as it takes some practice to become proficient. For us, time is money, and we've cut our measuring time in half! Highly recommended!

Bluetooth Enabled 330 ft. Lithium-Ion Laser Distance and Ang
This laser measuring device arrived when it was supposed to. This Bosch laser measuring tool seems to be made of high quality material and also seems to be very accurate. However, the user manual seems to be a little lacking for in-depth detail. I have not use this tool for a long time as I just received it. As I have checked it out, it does seems to do everything that was advertised.

BEST ANSWER: Yes, the unit of measurement can be changed
Reading reviews for both the GLM 50 C and 100 C, I tend to see a trend. Everyone who's bought either of the devices loves them for measuring but many customers can't get either to work with the Bluetooth-connected apps. Customers runnng Android devices, often with recent versions of Android, seem to have the most problems with this. As an Android user, currently running a phone with Android 6.0 and about to buy a tablet with the latest version of Android, I need to know if I'm going to have problems with either of the Bluetooth apps for either the GLM 50 C or 1000 C. Many of the user reviews stress the fact that they are using the latest version of Android on new, flagship tablets. Is it possible Bosch apps for these devices haven't been updated for the newest Android versions yet? Is this really a Bosch problem or is it just a bunch of stupid users who didn't read the instructions before giving up and complaining? I haven't read one iPad user app compaint, which does seem suspicious.

I've been reading the marketing copy on Amazon for the Bosch GLM 50 C and GLM 100 C. Other than perhaps the GLM 100 C having a longer range of measurement, what are the principal differences between the two devices? Admittedly, I haven't downloaded the full manual and brochure in pdf form, just read the sales pages, but it doesn't seem like there's much of a difference between the two from what I'm noticing. What am I mising? What functionality does the GLM 100C have that the GLM 50 C doesn't?
LUKE on May 25, 2016
BEST ANSWER: General comparison:

1.GLM50C: Measuring distance extends to 165 ft. with +/- 1/16 in. accuracy

2.GLM100C: (a) measures up to 330 ft. with up to 1/16 in. accuracy
(b) Optional R60 digital level attachment transforms the
GLM100C into 24 in. digital level (not included)
(c) Bluetooth functionality conveniently transfers and stores
measurements from the laser measurer to an iPhone, iPad or
Android device via free app
