The levels are completely disabled. It's basically an 8ft tape measure, 6ft ruler and laser all in one product. Find out for yourself what a level is and then use it as a marking tool. However, you cannot rely on planes to figure out what actually is a straight horizontal plane. Because of this, this tool is practically useless.
