I'm Trying acurate the point to point measure, because during the tests on tripod from about 4 meters distance from the window the measure result take 1,52m starting right side to left side and 1,45 starting left side to right side, but the correct measure of the window is 1.50m. The red laser is poor to sunlight, it's difficult too see 3 meters distance. Others functions look like ok.
very precise and handy to use. included (chargeable) batteries has less capacity than specified.
