Very good laser measure with Poor App
I have been very impressed with this laser measure. Compared with the 10+ years old Stanley TLM 130 it replaced, it is compact, lightweight and quicker to take readings. I particularly appreciate the better battery life and the inclusion of a tripod mount on the back. I regularly use laser measures to check construction drawings against new and existing building interiors and also to take site measurements/quantities for estimate preparation where drawings are not available. The red laser is clearly visible indoors, but I would not recommend this particular model for predominantly outdoor work. I would have liked the GLM50C to have a wrist strap to reduce accidental drops. Mine remains unscathed after a couple of unintended drops onto hard concrete but I don't think it is claimed to be "rugged". The GLM50C comes with an elasticated cloth belt case which is quite adequate. Initially, the device felt a bit slow to power up (actually just over 1 sec), but this may be no bad thing. I’ve not noticed any problems with accidental power-ons that constantly drained the TLM130's battery. The GLM50C takes two standard AAA batteries that are simple to replace however I’ve found that rechargeable batteries work very well. The rotatable colour display is very clear and the functions are intuitive and very easy to use but the standout feature is the bluetooth connectivity which enables measurements to be recorded remotely via a smartphone/tablet app. That said, the App (I've only tried the Android version 1.6.0) is incredibly frustrating. I know the bar for this type of App is pretty low, but considering this device has "Professional" and "Bosch" on the front, I hoped for better. The quick sketch floor plan builder is almost impossible to use on a small screen and even simple edit attempts result in insane (*) layouts being created. The app is (sometimes) easier to use with a tablet, but in practice I've found this a bit cumbersome out on site. There are bugs in the wall measurement functions (used to enter wall elevations), with the app insisting that an entered dimension must be wrong (eg a door opening, which the app considered wider than the wall). The ability to put dimensions directly onto a photo should be very useful, but this implementation is poor. Dimensions are difficult to position accurately and quite often one end of the dimension will stubbornly remain off screen. The magnified view of the target point "under your finger" would be great if it didn't stray out of sight so often. Frankly, the only useful part of the App for me is the simple measurement entry/storage/export. Single measurements can be initiated by either the GLM50C or from the App and ultimately exported as xls or pdf. Each measurement entry (grouped into a Project) is date/time stamped and can be renamed, although there's no facility to record GPS location nor select from (for example) predefined room names and measurement types which would have been so easy to implement. The GLM50C can store up to 30 previous measurements internally and this is plenty in my experience. This limitation does not apply to measurements stored with the App. The internal measurements are retained after a power-off and will even survive a battery swap. Tip: If you do decide to get a GLM50C, get yourself a cheap selfie-stick with a 1/4 inch standard screw mount to attach the GLM50C. Having greater reach and not having to press the button on the device makes all the difference. With practise taking measurements (via the smartphone app) will be simpler and quicker - even if it won't actually replace handwritten survey notes. Back to the GLM50C itself, there was really only one negative that I think will impact on the measurements I regularly need to take: I do wish it had a flip-out end-piece (like the Leica Distos) to allow taking diagonal dimensions into corners (especially since the GLM50C has a max/min function that's ideal for measuring into room corners!) The built-in functions are quite comprehensive (some seem more suited for "outdoor" measurement, so may not be used much), although I do wish that a 3D point-to-point measurement facility was provided somewhere in the range. Overall, although the current App is a bit rubbish, the GLM50C is thoroughly recommended as an "indoor" measurement device. (* I wanted to say Escher worthy, but that's a bad example - the App can't do stairs of any sort.)

Impressed
Currently fitting new wooden floors plus skirting boards, trim around windows and curtain rails (and doing the wife's job of shortening the curtains) and fed up with trying to stop my tape measure bending in the middle, coming unhooked, etc. If you have ever had to measure more than half a metre you will know what I mean !! Saw this little gadget on a deal and saw the accuracy of 1 mm and thought that's good enough for everything I want. In fact a lot better than I get trying to hold the tape straight. How right I was. My first thought after delivery was "It's a bit heavy". Turned out that was the manual. After the panic over a manual about 40mm thick. I then discovered it was in about 25 languages and the English was a few, not really needed, pages as its all a bit obvious. Just turn it on, point the laser and read the distance. Quick, easy and really accurate. A bonus is not having to write down or try to remember the measurement when I go into the garden to cut boards. Just read it off the display. OK, Once software gets involved all sorts of clever options are available such as area, volume, indirect (clever) measurements which are possible to work out without the manual but if all else fails and you are male, go somewhere private and look at the manual. I am just happy that I can take straight line measurements without needing my wife to hold the end of the tape. Oh and of course there is an "app'. I have downloaded it but not used it yet. The bottom line is that it's useful, accurate, easy to use and easy to keep in tool box. I probably would not have paid full price but now I have used it the full price is worth the expenditure. It does not replace my tape measure but its a really useful addition. I find the reviews of others help my buying decisions. If this has helped you please click the like so I know I am not wasting my time. Thanks

A laser measuring tool seemed like a handy gadget and a good idea that would make measuring floors for laminate and vinyl etc and walls for paper and paint quantities so much easier. I was aware that there are hundreds of similar tools on the market and so I set to finding one that was accurate, a trusted brand and not over priced. After going through the usual suspects I came across the Bosch tools and soon narrowed it down to the GLM 50C. Placed the order and it arrived on time as expected. This tool is brilliant, it has a Bluetooth option which allows the unit to be activated by the users mobile device. (When setting out alone for instance) Bosch have released an app for their Bluetooth units which allows users to set out plans of rooms to be measured, the user draws on the screen with their finger and the app squares the sketch then measurements can be added to the diagram. The app also imports photographs (to which dimensions can be added) There are other uses for the app but I’ve not ventured any further. The unit itself has numerous modes which will calculate square areas and room volumes, it even has a setting that allows setting out equidistant fence posts or other work that requires multiple set distances to be achieved. It even works as a spirit level and angle meter. It retains the last 30 measurements too. The only CON I have found so far is the case that is supplied. I find the case to be slightly small and it fits the unit very snugly. Because of this, it takes more than a moment to stow the unit with one hand when the case is on users belt. To sum it up.. I am more than happy with this unit, I love the Bluetooth connectivity and the options and additions it brings. The various modes on the unit and the ease of use have been both surprising and amazing. Great little device.

Fantastic if you want to use the app.
Ok, so I've used quite a few of these laser detectors over the years, they're really useful for professionals and DIY'ers, and I'm always surprised when I see a painter, floor layer, or plasterer without one of them, it helps you make an extremely accurate reading of any room and almost any wall. it will work against any material type but it will struggle when going through glass (but don't try to measure the width of a bathroom wall through the shower glass, the laser will reflect off the glass and that is the reading the sensor will take), the only walls it cannot deal with are free standing walls as they don't have edges to aim the laser at. So is the bosch any better than a lot of the ones out there that you can get for £30 or so? Honestly, not really no, it has basically all the same functions as the others, and if you want to measure wall lengths, ceiling heights, work out floor area or even volume even the most basic ones will do amazing jobs with similar if not identical accuracy as this one here... So why buy this one? well, it's absolutely all about the measure-on app, and it's not just limited to the measure-on app, it's the apps made by the Bosch partners that you're allowing yourself into, e.g. Floor Plan Creator, Magicplan, Measuresquare 2 etc etc, they all use the bosch BT on this device to essentially turn your measurements into impressive looking diagrams, quotes, project proposals etc... And it's quick, easy, and so incredibly useful. The measure-on app itself is free to download and works really well, but it lacks some levels of detail that you'd expect from a planning app, but it's fantastic as a baseboard for room plans... measure and connect via bluetooth and the wall lengths are in... =)

Fantastic upgrade
I bought the Bosch measure to replace a cheapo £20 "amazon special" laser measure that went missing and having used the Bosch would not go back. I've been using the unit for a few weeks now to measure up commercial buildings for refurbishment and very happy with the unit and the bluetooth link. Likes: (so many but the main points) -Green laser works in bright environments and reads much faster than the previous red laser I owned. -Clear easily readable screen which rotates to whichever orientation you are using the unit -Bluetooth link to phone with the Bosch app makes it simple to sketch floorpans directly to a phone rather than lots of different sketches and paper notes -The features - aside from the usual length/area you can do continuous measurement, stakeout and indirect measurements which I rarely use but incredibly useful whenever the need arises. -USB-C rechargeable so no more running out then trying to find AAA batteries. There is the ability to use AAA batteries but I just use the rechargeable pack and USB lead Dislikes: -Maybe the price (but its worth it if used frequently) -The floorpans in the app are limited. Hopefully this will be improved in future updates. Overall this is a fantastic laser measure and well worth the upgrade from the basic red laser measure I used to have. The bluetooth link for recording measurements and floorpans means I am no longer looking for that piece of paper. The measure is also fantastic when being used on its own, Bosch have nailed it with the QOL features like automatically rotating the screen to keep it readable when you hold it on its side so no more measure/rotate/measure/rotate when working. I would definitely recommend if you can justify the price

Very impressed and glad I purchased this over the GLM80 model that was ...
Very impressed and glad I purchased this over the GLM80 model that was on offer for a similar price, and the cheaper DLE40 that was on offer for a great price at the time. The GLM 50C covers a max range of 50m, I didn't need a longer range as I'm only measuring detailed floor plans for residential buildings so all models would have been sufficient. The main benefits of this model over the 80 is the Bluetooth connectivity and colour screen, I wasn't sure if I'd use the bluetooth but it's makes the job notably quicker. So far I've tested it with my iPad 3 and Android GS6 and it's worked flawlessly with the official GLM app that supports this and the GLM 100C. I've found it best to draw a quick sketch in a 3rd party app such as Autodesk Graphic or a paint package and then output that as an image to use within Boschs app, it's then just a case of drawing a dimension line and pressing the scan button to take the measurement, once done I then go back to my office and manually transfer the details to my CAD application, so no messing around with a pen and paper. The other advantage over the 80 is the colour screen, this provides functions such as the tape measure which works well for marking distances from a point. The big advantage over the 40 is the angle measurements, this works like a spirit level in the main view and helps to ensure you're holding the device horizontal when taking measurements, and because of the flat sides you can also rest the device on a straight edge to assist when marking out. The main thing this doesn't have that the 80 has (apart from range and the rechargeable battery) is the additional pull out measuring point, this would be useful but I haven't found it a major problem, the top and bottoms flat so aligning it with an exposed edge then using the built in spirit level to ensure it's level seems to have produced accurate results. All in all I've been very please, I've made a lot of detailed accurate measurements far quicker and easier than using my old tape measure.

The Bosch Pro Measurement tool
I going to say that i have been looking for measurement tools for 2 weeks now an i saw a few, but the Bosch was very expensive, brought a cheap one for £21.99 and it could not recharge and the laser measurement was very wrong. Started looking at the Bosch 50c and check a lot of reviews so i brought it. I work in fabrication so i need a measuring tool with a very low tolerance level and this boy seem to have done the trick. My work tolerance level is 1mm, This measure works with angles and have a great spirit level also with control of back measurement and front measurement of the device, also have a brilliant colour display clear clean numbers recognition. The Bosch app which i download on Tab S am still running test on it still, just the let you know i use this GLM 50c every day for my work and still testing it out from my measuring tape which the Bosch keeps up with. It will take me over 3 months before I can actually trust the Borsch to take over from the tape measure but so far it's been accurate. This is over 1 month and a week now, even the welders ask me to borrow GLM 50c for checking there angles even though they have the tools. this device is 9 things roll up in one and it's very good so far. Forget the price 'just buy it'.

A simple way to get accurate measurements for your DIY projects
This is the first laser measure I have owned, and I'm impressed with the basic features (I've not tried the full feature set for recording measurements). It is lightweight but feels solidly built, and works straight out of the box using the included 2xAAA batteries. It accurately takes measurement from a variety of surfaces and can be set to measure from the back, front or middle of the device with a dedicated button for this setting. I have checked the measurements with a tape measure to ensure it was calibrated correctly and it is accurate (Bosch quote a tolerance of +/- 1.5mm which is fine for most applications). The screen is clear, easy to read and displays the angle you are holding the device. Navigating the menu is straight forward (read the manual for what each icon represents) using the Function key and left and right arrows. Pairing the Bluetooth to my phone was easy. I have not used the Bosch app but have used another floor planning app and the measurements transfer seamlessly to that. The storage pouch is a nice extra.

50m mesafeyi ölçerken lazer ışığı görünmüyorsa fosforlu reflektör kullanın
Cihaz özelliklerine göre mükemmel ve kaliteli. Tek zorlanacağınız nokta; örneğin 40-50 metreye lazer ışığını tam istediğiniz noktaya eliniz titrediği için sabitlemenin zor olması ve mesafe uzak olduğu için lazerin ışığını hedef üzerinde görememek. Ben bu sorunu aşmak için; 30cm*30cm ölçülerinde 2 parçalı ve menteşeli-ayaklı bir plastik levhaya reflektör yapıştırdım. Ölçüm yapmak istediğimiz noktaya bu reflektörü yapıştırınca/asınca/ayakları üzerine koyunca, üzerine düşen lazer ışını çok net görünüyor ve gayet güzel parlıyor.

Perfecto
Producto comprado. Lo primero q llama la atención es su tamaño es muy pequeño para todo lo q hace. Casi no pesa lo q facilita su uso. El tacto es muy agradable y soporta el agua pefectamente, probado. La pantalla es clara y se ven perfectamente tanto las mediciones como la info. La navegación por todas sus funciones básicas es muy intuitiva, mi abuelo de 97 años aprendio a usar lo básico en 20 minutos Probadas todas las características esta es mi experiencia: En el interior ningún problema, es preciso, el láser se aprecia perfectamente y da mucha información. En exterior la cosa se complica muchisimo, pero supongo q pasará con todos, de día en distancias cortas vale, pero 50m ni un alcón peregrino encuentra el puntito ;) un consejo para exterior fabricaros un poste guía con cartón etc para captar mejor el láser, y daros cuenta que a cuanta más distancia 1 milímetro en la base es mucho mayor en el destino. Con día claro Despues de mucha paciencia y tiempo logré encontrar el punto, distancia 30m, a más distancia no miré. En mí opinión buen producto no me arrepiento de comprarlo

Bom desempenho e precisão
Nota 10 para a Amazon, como sempre ajudando os clientes em todas as dúvidas. Ótimo produto, envio rápido, excelente desempenho para uso profissional, testado em uma medida de 30m de comprimento a precisão foi de 100%, em uma medida de 48m a previsão foi de 100% em uma medida de 50m a precisão foi de 99,4%. Custo benefício: Para uma trena de precisão até 50m achei o valor meio salgado, mas para quem busca praticidade e rapidez eu recomendo, pois essa trena possui varias funções se comparando com uma do mesmo modelo comum. Tecnologias: Ainda em fase de testes, o bluetooth funciona perfeitamente, as funções de níveis 100%, medições em diferentes tidos de posição 100% Recomendo, produto original BOCH
