Astro Compass Pro is a unique, high-precision professional instrument that is unlike any other compass in history. Find your way, day or night, and in any weather. Orientation has never been so precise and easy. There are no ads, and no cell service is required.
Astro Compass Pro uses GPS data to calculate the position in the sky of the Sun and the Moon using advanced astronomical algorithms with accuracy down to 0.01 degree. By orienting your device with the Sun or Moon as instructed in the easy-to-follow help screens, the compass then accurately aligns with the Earth at your location.
Five unique aiming modes are provided, including standard magnetic field sensing as a fallback when the Sun or Moon are not visible, allowing you to orient yourself to the cardinal points of the Earth both day and night and in any weather.
Way-points are provided, one labeled for your car, and the other for your camp, although you can use these to mark any locations you want to return to, or to any point on the Earth by entering its latitude and longitude. Distance and direction to each way-point is constantly displayed in your choice of English or Metric units. All data and settings are retained for the next use, even when you cycle the power on your device.
For example, you might have a favorite fishing hole in the woods. You can enter the latitude and longitude for this spot as your "camp" way-point as you prepare for your expedition. As you hike through the woods, the camp pointer will continuously point you in the right direction, and let you know your distance from the spot.
Standard magnetic compass accuracy can be poor, due to nearby metal objects, and due to normal variations in the Earth's magnetic field. Also, the declination, or error between magnetic north and geographical north, varies widely all across the country and around the world. By using the Sun and Moon instead, these problems are completely eliminated, and true geographical north is found with high accuracy.
We live in a different world, and Astro Compass Pro sets the standard for a completely new type of compass. Let us know how you put its precision and accuracy to work in your unique explorations!
