This is a simple 2 stage offset multicache. You will need to apply a bearing and offset from the published coordinates to find the final geocache location.
At the published coordinates you will see a sign with 2 numbers. The white number on red background we will call A. The black number on white background we will call B.
You will find the final geocache (A / 2) metres at a bearing of (B x 3) degrees true.
The final cache is a small screw top container with waterproof log and room for small swaps.
Please ensure the cache is hidden properly in its hiding spot and cannot be casually seen. BYOP.
Good luck and happy caching!
