A quality meter

Finally something new in the world of laser measurers! This small object, provided with his belt cover, handy on construction sites, will measure your walls and parts of 5cm to 30m (or 40m depending on model) with an accuracy of 2 mm, no less .... it has area calculating functions and volume and calculating sum or subtraction on the measured values. Its color screen is small but very readable and well resolved. It shows the min / max distances obtained during the measurement phase and the final result. We first advanced laser red spot and the measurement is made. Continuous measurement is also available.
The most interesting summer blue tooth connection with an application iOS (and Android) very well done and very friendly which enables distances to postpone action on plans or even photos. A real plus to create a project and especially its measures take with you to buy a piece of furniture or materials without pieces of paper .... one weak point, I did not find the opportunity to change Metric US units / UK damage.
