Rated 5 out of 5Â by tnahpele There's a lot to say about this little gem.
It comes with a lanyard, belt holster, 24" Micro-B USB cable for PC connection and charger.
It's smaller than I expected, but study and easy to handle.
I found the lanyard attachment fussy and it got in the way, so I ended up not using it.
The back-lit display is easy to read except at extreme angles when it washes out.
There are 4 measurement locations that can be selected - front, back, tripod mount, and from
a 1.5" fold-out pin on the back that allows measurements in corners or other hard-to-reach places.
There are a number of units settings that can be changed at any time, but it requires going into the GLM basic settings to change it - it's not a simple button press.
I checked the calibration first. Taking 10 measurements at a distance of 10', the maximum variation was 1/32" (0.8mm), handily exceeding the 1.5mm accuracy rating.
The angle calibration was off by 0.8 degrees, so I followed the calibration instructions to recalibrate. It was difficult for me to understand the calibration diagrams on the screen, but it's a simple 4-step process. (1) Lay it on its back, (2) swap ends, (3) lay it on its side, and (4) swap ends. The end result was a match within 0.2 degrees, again exceeding the 0.3 degree accuracy rating.
When measuring angles and used on its back, angles can be measured from 0 to 60 degrees. When used on its side, all angles can be measured. On its side, it beeps to let you know when you're within 0.5 degrees of level, beeping faster when you reach 0 degrees.
The screen automatically rotates from vertical to horizontal when the GLM is tilted sideways, but unlike a smart device where the screen will rotate at a 45 degree tilt, the GLM doesn't rotate until it's within 5 degrees of being horizontal. I found it much easier to just lay it down on its side to get it to rotate rather than hand-holding it sideways.
It has a bunch of functions that you can read about in the product literature. The unique feature of the GLM is integration with your PC, iThing, and AndroidThing. All the associated software and applications are free.
The GLM can retain up to 50 measurements. These measurements can be downloaded to a PC using the GLM Transfer Software. You connect by USB with the PC, open the GLM Transfer Software, and press "Get Data". It connects to the GLM and imports and displays all the measurements. From there you can transfer them to an Excel spreadsheet, the clipboard to be pasted into Word or Notepad, or a text file. You can also erase the measurements on the GLM. I tested the program on a Windows 7 PC and it worked flawlessly. The only hiccup is that it says "not connected" until you press the "get data" button, leading me to initially think there was something wrong with the USB connection. The Transfer Software displays and exports data in the units set in the GLM
The IOS and Android apps do not import stored measurements from the GLM. Once connected by Bluetooth, any subsequent measurements you take with the GLM are recorded by your smart device. The smart device can also be used as a remote control to operate and change settings on the GLM. There are separate settings for the GLM and the app, so you can have one units setting on the GLM and a different one on the app.
The most amazing feature is the "sketch" option in the smart device app. It lets you take a picture of the thing you're measuring, draw in measurement lines or angles with your finger (including a neat "zoom" on the line ends to allow precise placement), select an item, and then the next measurement you make with the GLM is attached to that item. I tested the app on my iPod Touch 5th generation (IOS 7) and my Android 4.0 tablet and it worked well on both devices.
I used the GLM to take measurements for a heat loss calculation in my house, including window and door area, wall lengths, and room volume. While you can do addition and subtraction in the GLM, I chose to import the measurements for each room into an Excel Spreadsheet and do the final calculations there.
There are a couple of things to be aware of:
1) The GLM doesn't pair with IOS devices, you get a "pairing is not supported" message. So don't try to pair it, just open the "GLM Measurement" app and press the "connect" button.
2) Android is the opposite - pair Bluetooth with Android, then open the "GLM Measurement" app.

Rated 5 out of 5Â by sdgiant Great tool for Contractors and Estimators
I've got to say, connecting a laser measuring device directly to an Android or IPhone is a very useful innovation. You don't have to transfer measurements from your laser to your phone, you use your phone like a remote control for the GLM 100C.
You just hit a button on your phone, and the laser clicks, and the measurement is already there on your phone, and in the context of your previous measurements in a series... And you can pair those dimensions to pictures you take on your camera. No more trying to figure our which room those measurements go with.
The phone app can save numerous measurements, and you can create project folders. You can copy the results to your computer with the included USB cable (and charge the GLM 100C's rechargable batteries too.)
Using the phone as a remote control to take measurements has the added benefit of letting you place the device and not accidentally moving it when you hit the trigger button. Minor, but nice upside when accuracy matters.
The GLM 100C also has a built in gyroscope, so you can measure angles. That means you can measure large vertical walls to any end point (like second floor height) just by measuring the angle and length to the top and bottom and calculating the third side of the triangle. Saves you a few ladder trips.
Be patient setting up the Bluetooth pairing with your phone. I put another video on YouTube just for that. The instructions on pairing were a little weak. It will eventually pair though, and once it does it's easy after that.

Rated 5 out of 5Â by MEWs I use it nearly everyday! Highly efficient tool
I bought this tool a few months ago, and it so effective, efficient and convenient. I am a commercial real estate broker. I use it every other day to measure industrial properties. It saves me a huge amount of time, and all of the client's are always so impressed with my us of such a professional accurate tool. Thanks Bosch !

Rated 5 out of 5Â by Texas Simple, or fully featured, your choice.
In its simplest form, without pairing to your phone, you can quickly and accurately measure distances and angles up to 330ft away.
The real power of this unit comes to life when you pair it with your iOS or Android device using the free application. Not only can you trigger the unit from your mobile device, but it also records the reading to the device itself.
Take a picture of the area (or select an existing image, like a site plan for example) you are measuring with your smart device and quickly 'sketch' the measurements. No more pencil and paper sketches to have to transpose. You can easily share these via email.
When connected to your PC you can pull in all the historical readings. The smart phone app can not pull older data, it only records data sent to it when paired.
There is a positioning pin at the base that folds out to 90 degrees when measuring onwards from outer corners, or 180 degrees when measuring from a corner.
The tool also accommodates a 1/4" thread mount for a tripod base.
Measuring a large metal building with tables, benches, and tools throughout would normally take a while to plot out with a tape or measuring wheel. I was able to measure the whole building in less than a minute. Using the sketch mode, not only did I measure the building, but I marked where I wanted the extra window, and emailed it to my contractor.
What would have taken an hour to do before, was done in 2 minutes. Just amazing!

Rated 3 out of 5Â by Brian Nice...But, A slight challenge for quick measuring...
I have only had a week or so to test this thing out and there are noticeable changes that could be made to the unit to make the process quicker and more user friendly.
To start with the device itself without the app, it is a great laser measuring device with very tight tolerance. If you want to use it just for that it should serve its purpose well but there are cheaper ones available if you chose not to have any app based ad-ons. Now for the the whole Bluetooth paired device deal...it becomes paired once you fumble through the app and hit the bluetooth button on the device however, once it powers down you have to pair it again and again and again which takes too much time when you are in to measure a job quickly and generate higher profit margins. It is an absolutely awesome concept and I have used it with my iPhone5 and it works as it should but to add dims on such a small screen is kind of not worth the time if you do not carry a fine point stylus because your finger tip blocks view of where a dimension arrow is placed and with quick work this takes up too much time. If you carry a large tablet like an iPad it would work much better but due to conditions, you may not want to break up your personal iPad device in the field given that they are expensive once you get them protected and filled with apps and such. To those getting into the thought of using this device, you should spend a considerable amount of time playing with every function in order to become greatly proficient with the device and the app. I certainly will use it where I have room in the budget on a tough, intricate project but will stick with simplicity on the smaller boxes where a hand drawn sketch will always be much faster. Give it a whirl if you like to be the most advanced person in the office. As I said, it is an awesome concept and will certainly help on largescale, intricate projects or specific items within a project that you want to transport or relay back to the office from your handheld device to an employee at the ready to take info in and modify, resolve any issues apparent in a photograph with dimensions from the device. Once I get more time with this device, I will try and follow-up with a more detailed review...a week is just not enough to go through this whole device and all of its functions. It seems it would be great for estimating but I just have not reached that point of comfort with it yet. The bluetooth pairing everytime it powers off is a bit of pain since most all devices once they are paired will pair automatically when turned on...this is certainly something for Bosch to improve. There are a few coworkers in our firm that lost interest within a minute of playing with the app so I am honestly on the fence about recommending this product but I will to those savvy enough to want to take the time to learn it.
