1. The angle displayed is always less than 45 degrees. (ie, 4 degress instead of 86 degrees, and 2 instead of 92)
2. It is possible to quickly set zero orientation and measure angles relevant to this zero. (if position of setup board is not absolutly horizontal, and the sensor is not always working perfectly.)
3. Adjustable speed/accurancy.
