Cache is not at given coordinates.
This puzzle is very loosely based on the game battleships, where players take it in turns to fire on their enemies’ ships by using a simple set of grid coordinates. By using the following information, you should be able to obtain the coordinates you search for. Cachers who have completed the puzzle for GC47GNT may find this familiar.

Once you have obtained the coordinates, the cache can be found just off a public footpath. This path is usually muddy and can be busy at times, so decent footwear and stealth are both advised for this cache.
Good luck!
