Bosch GLM 50C Review: Both Professional And Powerful!

While most of the field engineers still rely on the conventional way to measure the dimensions, Bosch is trying to help them with innovations. One such innovative technology from them is the new Bosch GLM 50C Laser Measurement device. If you are a field engineer then at some point in time you might have felt that carrying measurement tapes or scales everywhere is a significant pain. While it’s easy to measure small length or height with tape, it’s not the case as with the great height or length. To help you with such problems, this device is a kind of gem which every field engineer should consider.

Bosch GLM 50C Review

Bosch GLM 50C is a digital laser rangefinder device which uses the laser technology to measure dimensions anywhere. Just point the device to your target, for ex a ceiling, a bridge pylon or a multi-storeyed building, click the button and then you will get the dimensions on your device with an accuracy of 1-3mm.

Bosch GLM 50C Review


Bosch GLM 50C has got tons of different features which are pretty useful. The device allows you to measure lengths/heights up to 165ft with an accuracy of +/- 1/16 in. With the built-in inclinometer, you can also measure the angles of your desired target such as a slanted rooftop or transitional curves on the road. You can switch to different measurement units like volume, area, height, length real-time with just a button on the device. Another feature which is pretty useful is the Bluetooth Connectivity which allows you to connect the device with your smartphone to record the measurements of your desired target on a sketch. The backlight on the device allows you to view the information even in the dark. The display has an auto-rotation feature which is very useful to measure dimensions at different orientations. The device has a digital level which can be used as a replacement for a spirit level. The device runs on AAA battery which is okay but considering the advancements and the type of usage of this device, people would still prefer lithium ion battery backup for this device. However, some people may find it easier to replace the AAA battery with the new one during a project instead of taking out some time to charge the device.

Build Quality

The build quality of GLM 50C is pretty good. The device is lightweight and handy. You can keep it in your pocket as it just weighs around 300gms or you can use the belt strap. The quality of the material is durable, so even if it accidently falls on the ground, it won’t break easily. However, the device is not waterproof at all, so you need to be careful while using the device when it’s raining.


Before using this device for all your professional work, you should be aware that the measurements are not 100% accurate and have an accuracy of around +/- 1/16 in. While this is okay for rough measurements or survey, it shouldn’t be used as primary measurement equipment while preparing dimensional drawings. Also, for lofty heights or distances, the device works best when used with a tripod. More stable your device will be, more accurate the results are. Since the laser consumes a lot of battery, you need to carry some AAA batteries with you as a backup if your device runs out of battery in the middle of your field project. Although the device can store up to 30 values, there is no timestamp on the readings. Hence, it would be better if you connect the device with your Tablet or Smartphone and record all the details on it considering the future perspectives.

Final Verdict

Bosch GLM 50C is available for $150 (Rs 10000) and for this price it’s a very useful and handy tool for the field engineers. If you don’t have any issues with the slight measurement accuracy, then this can be a great companion for you on the field for rough measurements. Bosch is one of the most trusted brands in providing engineering equipment, investing your money on this device would be worth considering. The device also has a warranty of 2 years from Bosch. The device can be bought through Bosch’s official website or even through Amazon.
