Explorer Challenges

The Explorer Challenges are based on the Ordnance Survey Explorer maps. To qualify for these challenges you need to have found caches in the same number of squares of the map as the map number itself. For example the first cache placed in the Explorer series was GC37A2A Explorer 133 Challenge. That challenge is based on the OS Explorer 133 map which covers Haslemere & Petersfield, and the requirement is to find caches in 133 of the 600 squares of that map. The other challenges in the series follow a similar pattern.

 

There is a GSAK macro that will help you check your progress on these challenges. I've completed two of them at the moment.
