Geocache Description:

The co-ordinates given are not the co-ordinates of the cache, but are just rough co-ordinates for the start of your search.

This puzzle cache is based on the game Battleship, and has 26 parts including the final cache. With a bit of luck and logic, you will not have to do all of these parts. All of the parts are around Horwich, Blackrod and Rivington. The final cache location can be seen from many of the parts (from a distance, of course).


Below is a 5x5 grid, with each of the squares numbered 1 to 25. Each square has a set of co-ordinates and a statement, which is true or false. You need to visit that location to find out if the statement is true or false. If the statement is true, then the square is a 'hit' and if it is false the square is a 'miss'.

Hidden within the grid are 3 battleships, which you have to sink in order to find the final cache. The battleships are 2, 3 and 4 spaces long, and are named 2-ship, 3-ship and 4-ship respectively. Each of the ships is travelling either North or East.

The numbers are not the order in which the parts are to be done, as this is entirely up to you, although it should be noted that some parts are near others, even though their squares may not be near each other on the grid.

The final cache is at the following location: N53.3A.BC8 W002.3D.EF0

where:
A = End of 2-ship divided by 2
B = Front of 3-ship minus the middle of 3-ship
C = End of 4-ship minus the front of 2-ship
D = Front of 4-ship minus 3rd square (from the front) of 4-ship
E = Front of 2-ship minus the front of 3-ship
F = End of 3-ship minus 1
