GC3ETP0 Unknown cacheExplorer 145 Challenge

Find caches in 145 grid squares of the OS Explorer 145 map.

There is a GSAK macro that you can run to calculate your total. On the day I found the cache mine was 168.

 

You can find the latest count of squares for this map on my Explorer Challenge page.
