The GLM 100 C from Bosch is a bluetooth-enabled laser measure. It comes with an app so you can instantly transfer measurements to your laptop, tablet or smartphone wirelessly using Bluetooth. Most Bosch tools aim for perfection, but this one actually comes pretty close by combining a massive 330-foot reach with ten precision laser measurement modes and the computing capabilities of smartphones and tablets. You can store up to 50 measurements and take two-axis angle measurements. You can remotely control the GLM 100 C using the app on your smartphone, a feature which comes in very handy when you have to take measurements in hard-to-reach places. It has a rechargeable lithium-ion battery, so you won’t need to buy any batteries either.
