About this tool

This tool was developed for Mystery-Caches. Every Cacher can confirm the accuracy of his results.


To prevent abuse of this tool every cacher can only check five coordinates in 60 minutes. To check every coordinate in the region from N 51° 25.000' to N 51° 26.000' and E 006° 45.000' to E 006° 46.000' you need 22,8 years. Ask yourself whether this is worth the time.

How do I check my coordinates?

If a cacheowner offers the GCChecker for his Mystery-Cache, you will find the following logo in the cachedescription.

If you click on this logo you will be forwarded to a form where you can check your coordinates.
