By contrast, this little Bosch unit is a fraction of the cost, and addresses some of my standing complaints about the Leica.
Primarily, the GLM 50 has an awesome, easy to read display. I'm not sure if it's backlit LCD, or OLED, but no matter -- the high contrast white on blue is legible in bright sunlight, dark basements, tilted sideways, whatever... without squinting! Contrast this to the small digits displayed by my A8, dark gray on a grayish/green screen, with a manual (and not very effective) backlight button.
Also, this unit is square. It sounds like a "no duh" observation, but the A8 has an ever-so-slightly off-square bottom edge that meant when I set it on a floor to shoot the ceiling, I'd have to manually tilt the unit just a tiny bit to get a straight shot. This Bosch goes a step further and includes a level indicator on the display, so there's no guessing whether the unit is oriented correctly.
The A8 has a handy camera viewfinder feature that allows visual targeting in situation where the laser dot can't be seen (long distance, outdoor). That's missing from the Bosch unit, though it isn't a feature I used much. In contrast, the Bosch gives me the Bluetooth connectivity to an Android app, but again, I haven't seen fit to use it yet.
The one feature I did use from time to time on the Leica that's missing from the Bosch is a timer, which would allow me to set up my shot without worrying about jiggle from the button press. I'll just have to make do without it, but it seems that Bosch could have easily thrown that in as a menu option without any extra effort.
Speaking of the menu, the operation of the GLM 50 is fantastic. All features are available with the press of a function button, in a "wheel" type menu. Each function is accompanied by a graphical depiction of the intended usage on the display, resulting in a relatively intuitive operation without referring to the user guide.
All in all, Bosch gave us a really good unit here, that despite the low price, doesn't much sacrifice in features, and excels in usage.
I got the 50C because I need the accuracy to be within 1/16", and this was the cheapest one that did that. I am a door specialist and we need to be accurate to 1/8" (as this is the size of the gaps between a door and its frame). This device is great, but it doesn't fully replace a tape measure. For example, the laser needs something to hit, so if you were measuring, say, a table then you could lay it flat on one end but it has nothing to hit on the other end. This is where a tape measure is faster and easier to just hook the edge and drag to get your measurement. So I now find myself taking both this and a tape measure to job sites.
Another great feature is the leveling feature. Some fellow techs and I tested it against a level app on a smartphone and an actual bubble level. Surprisingly, all 3 were accurate and gave the same results.
I haven't had the need to go in to its further capabilities as far as area calculations, drawings, and Bluetooth to the app, but so far its great... just wish it was half the cost!!! This type of technology is not new and they are definitely gouging a bit. This should be $50-60... not $100+!
I wish I could give 4.5 stars instead....the app needs some work and it annoys me that the laser device doesn't have the option to keep Bluetooth "ON" between uses (powering on/off). I always forget to turn it on and it takes a little bit for my phone to pair. Small but annoying.
Positive thing - exporting the measurements, photos and/or all as a report. Photo is a page of my window measurements PDF.
Also the FAQ helped me with functions that I had no idea even were possible.

I have been using the smallest bosch GLM 30, and it was not up to my professional needs. I still keep it as a backup for indoor use, should my GLM 50c fail. I spent an absurd amount of time researching my next and hopefully last laser purchase. There are few comparison videos and most of the reviews online were by sponsored idiots. The Amazon reviews contained the most information I could find. In my opinion, this is the best sub-500 dollar LDM out there.
Un-answered questions I had
- What is the bootup time on this software heavy device (3 seconds)
- Is the level feature incorporated into other software elements (Yes)
- Does it have a tripod screw (Yes) but plastic, oh well
- The menu system is a breeze, I was able to test all of the features within 30 minutes without using the manual
- This has a more powerful (Class 2 ) laser and reflective targets, a big help during outdoor measuring days.
- Does it come with a crappy case that fits too tightly? (Of course)
- Are the buttons independent or are they those shitty pill pack style (Independent)
- Does it seem like it can take a good beating? (Yes)
- Can it round to the nearest 1/8th? (No) for some reason, all of the LDM's, so 64th's!?!?
- Does the Bluetooth actually work? or is it just more marketing wank? (Works flawlessly on a Pixel 2 XL with Android P)
I was attracted by the photo with large digits on display. Unfortunately, large digits I only saw the first time I started the unit. After, the display shows a few previous measurements, so the current measurement is shown with much smaller digits. The good - display is bright enough indoors, and there are no issues with viewing angle.
As mentioned in previous reviews, the default state every time the unit is switched on is real-time measurement, which is fine when a unit can be put still on a surface. However, I have to switch to a single measurement mode to hand-held the unit to do a measurement (most of the time, in my case). Good thing is that the unit keeps the set reference point and measurement units.
More things I do not like:
1) Switching settings is suboptimal: it takes several buttons pushing to switch measuring mode, units, or reference point
2) The reference point in the middle of the unit is useless as it is not marked
3) First Bluetooth pairing took 15 minutes, and few restarts of the unit / two restarts of Bluetooph on the phone
Now to the app (MeasureOn for Android) which I use on Android phone with 5.2" display. The concept is nice, but realisation is not there.
App is not intuitive; one who needs the app will have to watch YouTube (where the app is called Bosch Measuring Master App), twice in my case.
The app is OK for creating simple floor plans of square rooms.
The app is difficult for a floor plan with more than one element. I attach a picture of the floor plan I failed to create using the app. First, a sketch is to be created (basic floor plan). I did not find a way to position internal walls on a plan. It seems impossible to draw a wall and then to set its position relative to other walls, so the sketch is basically limited to a floor plan with perfectly rectangular elements.
To add windows / doors to the plan, a sketch needs to be converted into a detailed plan. Once converted, the sketch is gone - you need to a create a new sketch if you miss something.
Adding windows, doors, switches, and receptacles is fairly straightforward, one need to switch to a wall view to do so. Strangely, receptacle size is 7cm x 7cm, which isn't a case, and I was unable to set a size (not to mention double or triple receptacles).
Now: the detailed floor plan assumes that measurements in the sketch are OUTSIDE measurements of the room, so every time you will have to adjust every wall on the detailed plan (yes, EVERY wall - opposite walls of a rectangular room need to be adjusted separately). On the detailed plan, I am still unable to add internal walls to exact places where they are.
After a few hours of trying over and over again, I give up on the app functionality, to return to other (computer-based) tools of drawing floor plans. Again, the attached floor plan is something simple, but I was unable to create the like using the app.
Overall: an OK tool for measurement, yet overpriced because of the bluetooth+app functionality which isn't useful
The feature to calculate height using the angle and current distance is by far my most used and I find it's accuracy to be spot on as well.
I would highly recommend this as it really truly does speed up all measuring tasks. It has also been valuable in estimating cable length requirements and so much more! A+++
The bluetooth was a bit finicky at first but in order to use it, turn on bluetooth on the device, open the app on your mobile device, then from within the app select "bluetooth", then with that on the screen go to the mobile device bluetooth menu, select the GLM50 device, pair it, go back to the app and it's ready to go!
I downloaded the app, and it makes construction mockup and planning almost painless.
At first it took me a bit of time to trust the measurements that it gave on my first project with it, I always double checked with a tape measure, and low and behold it was always spot on.
Is smaller then I expected but easy to read and use
I really like how easy it is to read and appreciate when the screen rotates with its orientation when measuring. So much easier than deciphering the scale on my tape measure. Switching between imperial & metric is easy and important to me because I use both scales for my projects.
Its Bluetooth capabilities was a major factor in my decision to purchase this. My initial purpose was to accurately capture floor plans to build custom cabinetry. I use SkecthUp for design but still need the initial "as is" measurements to start the process. (I'm not aware of a way to integrate measurements from a Bluetooth measuring device into SkecthUp).
So why did I only rate this 4 out of 5? I had hoped the free Bosch MeasureOn app would be sufficient to meet my basic floorplan documentation needs, it didn't. After a reasonable attempt at using it I found it too limiting so I'm now using MagicPlan which works with the Bosch GLM 50 C. (PS: Bosch, if you are going to dub German speakers in videos explaining how to use the MeasureOn App to an English speaking audience don’t include both languages in the audio. Also, when you create English only tutorial videos, don’t add an introduction for every 45 second video. Spend more time showing how it works and how to use it).
While this is a great tool on its own there is another thing Bosch could do to make it better. Allow a user configuration to set the default measure mode on power up. Currently its "real time" which means the laser is on when you power up. Two draw backs come to mind with this. Safety - are people thinking about where the device is pointed when its turned on??? Battery life - I'm assuming the laser is drawing more power when on, why waste energy while the user decides what and how they are going to measure? I've had the device for less than 3 week and am on my 3rd set of batteries. I'm not sure if this is normal as I've taken lots of measurements trying different apps and getting a feel for the device. Battery life was not something I considered when I bought it. Time will tell if it’s a factor. I may post an update down the road.
Having said all that, I'll keep it and hope Bosch makes it a 5 Start product.
Excelente para medir y guardar las mediciones en la app the tu telefono, hace lo que se dice
Las baterias duran 1 semana o un mes maximo dependiendo del suo que le des (casi nada, max. 1 mes).
Util solamente en lugares sombreados, imposible ver el punto de laser a 6 metros de dia en descubierto.
Bref, 4 étoiles pas plus et j'aurais payé moins pour ce produit.
Si nunca se ha usado uno, cuesta un poco entender las funciones, hay que practicar bastante (el manual no ayuda mucho así que casi se guía uno por la intuición).
La interface del equipo viene en inglés (no lo he podido cambiar a español, si es que se puede).
Imposible de usar en exteriores a más de 10 metros con sol intenso, pues es difícil de ver el láser.
Fits in the pocket! Comes with a 90’s carrying case for the belt. It’s actually kinda handy just a little tight.
100+ Long range outdoors is kinda hit or miss, but indoor it’s flawless. Love the real time mode for sizing up rooms without missing a beat.
