Cache is on the coordinates. You must meet certain requirements in order to log in the find in this cache.
To log this cache you have to visit at least 6 countries, and have found a different cache type in each country. All cache types except lab-caches are accepted. Size, date, D/T rating do not matter, if only you can prove 6 different cache type finds in 6 different countries.
Before logging cache as "Found" on the internet, of course you have to visit the cache and sign the logbook.
But you can not log the find until you meet the requirements (in this way you don't have to return to sign a logbook after meeting the requirements!)
To prove you have fulfilled the requirement, paste your result from the checker.
