The LED magnetic field detector compass has many features and designs to choose, but the best are the various digital features, such as magnetic field detector, GPS navigation, LED light and location sensor. In the upper part of the precise compass app, the magnetic field strength is displayed in μT (Micro Tesla). The All in One compass shows you the correct position and the exact digitally compass data to the location sensor. In the dark, you can simply turn your LED flashlight on and off for fast bright light by the LED camera light function. You can save GPS positions of your favorite places and let you navigate back to the stored positions if you had previously activated your GPS Location Sensor. The high precision magnetic field detector and compass is a simple helper for orientation when traveling, camping, picnic, hiking, outdoor activities and boating.
