Checking your answer before you go
Many puzzle caches include a checksum so you can confirm your final coordinates, like "the digits of the final add up to 47" or "the digital root is 5." CacheCrack writes the coordinate in standard geocaching format, including leading zeros, and adds up the digits several ways: all of them, the latitude and longitude on their own, only the digits after the decimal points, and the digital root.
Type the target number from the puzzle and CacheCrack tells you which sum matches. Put several possible answers on separate lines to compare them at once.
Example
N 42° 20.123 W 083° 03.456 has digits adding up to 43, with a digital root of 7.
