8+1 LED lights allow easy reading of the results and the power on/off status in the dark.   The range that correlates to each color is printed right next to each light in Milligauss and Micro Tesla.  Milligauss and Micro Tesla are the units of measure so we know how strong the anomalous and natural readings are.   Very simple to use.
