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.

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.)

When a tape measure just can't reach.
What I liked The compactness easy to put in your pocket or bag or the gloves box of your car but don't leave it there due to excessive heat during the summer months , it's well made and the booklet that explains how to use it and the technical information on the screen. It's easy to use,just use the function button then press the +or - button and select the function you want. Then press the laser activation button and there you go. The booklet is quite thick but it covers 36 languages, there only 10 in English. They screen is clear a cool blue and easy to understand once you have read the manual, the colour of the unit itself is also blue with a rubberized black edging to assist with holding the unit in your hand . It's got bluetooth feature that I have used once, but I have to familiarize myself again to explain it but it usefull as in the measurement are recorded on your phone and if you have a note pad there as well so you will have a electronic recording as well as a hard copy if you want to use this tool this way. The measuring unit has seven functions I won't explain them because they are in the instructions manual. It comes in a carry case that's very convenient and useful. When not using it for any long periods of time take out the batteries which will extend the life of the batteries and avoid the risk of the batteries leaking into the unit with the affect of damage to the measuring system. Overall very useful if you need to find the area for the new carpet that your going to buy, or too work out the number of kitchen cabinets you will need to replace the old units, or the area of your ceiling if your going to buy new plasterboard for replacement of old or the height of a building . Just useful for places where a tape measure just can't go. Dislikes None yet but i am looking.

The perfect measuring device that aves you valuable time!
Absolutely spot on! Searched for quite some time before making the decision on the GLM 50C. It does everything you want and more. I only use it for domestic purposes, but it saves so much time and turns those chore's into a breeze. The Bluetooth facility and app are very easy to use and also help's you achieve precise measurements by using your phone to record for those awkward angle's. Alternatively using a tripod makes it even easy to avoid those shaky hand measurement's. The one thing that's not mentioned on a lot of reviews is the devices ability to measure horizontal to vertical angles in degrees! I required this to calculate the placement of a Dolby Atmos in ceiling speaker at a 45 degree angle from my main listening position in a home cinema set up. The results using this device were perfection every time! Also made measuring the wood required for a projector screen letterbox plinth an absolute doddle! Photo provided. Highly recommend and a valuable piece of tech to have in my bag of tools! You won't regret it.

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.

Very good
Great tool for speed and recording measurements. Download the Bosch app and you can simply measure against photos that you take. Definitely better than dodgy sketches that I would loose or get mixed up with. Would highly recommend. Measured an 11m distance outside and the green laser was still visible. Accuracy is very good, I used to check measurements just to make sure and every time would be 100%

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

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

Uzun süredir alımını ertelediğim bir ekipman iken sonunda takım çantasında yerini aldı. Benim için tek dezavantajı gündüz vakti açık havada (balkon vs) kırmızı lazerin okunma güçlüğüdür. Yeşil Lazerli modeli bunun da üstesinden gelse de şimdilik aradaki fiyat farkı sebebi ile bunda karar kıldım. Kırmızı ve yeşil Lazerli modelleri ayırt etmek için üstündeki ok butonunun KIRMIZI ve YEŞİL renkte olmasına dikkat edebilirsiniz. Açık havada ve biraz daha ağır hizmet şartlarında çalışmalar yapanlar Ip65 serrfikasına sahip yeşil lazerli modeli almaları daha sağlıklı olur. Ev ve ufak tefek işler olsun, iç mekan ağırlıkla çalışmalarda bu model (50C) gayet de yeterli olur. Ürünün ayrıca eğim - su terazisi gibi özelliklerinin olması da ayrı bir güzellik. Amazon'a güzel bir indirimle bu ürüne sahip olma hakkını verdiği için teşekkür ediyorum.
