We are currently experiencing issues with connecting to the Gecocaching.com LIVE api. This potentially affects both our authentication system and how we retrieve data.

Find Bad Logs

By authenticating your account with Project-GC you will get access to many things. One of them being the Find Bad Logs tool, which is an excellent tool to find out if you have created duplicate found logs on a cache.

The tool will also show you if others has created duplicate logs on your caches or you have logged caches that you own yourself.


Dup logs on owned caches

Lists caches that you own that has received more than one found log from an account.

Dup logs

Lists all caches that you have made duplicate found logs on yourself.

Logged owned caches

Lists caches that you have logged but own yourself. There are no guidelines against this, but it's generally frowned upon. 1

Common for all the lists is that you can click a GC-code to get to the duplicate log.
