Level, then

In fact, it is quite simple to identify unevenness — it is enough to use the construction level. However, a modern electronic level will greatly simplify the task. Such a device is simply in use, and therefore any person can use it, and even very far from construction tools. But it should be noted that, despite the easy control, the level is highly accurate. If some difficulties during measurements may arise with the usual level, then the electronic device will instantly give out the result without any error.
