This was going to be part of a challenge cache series, but there is a moratorium on challenge caches, so I have converted this to the start of a puzzle series in the same theme. The cache is not located at the published co-ordinates, you need to solve the simple sudoku puzzle.
The cache can be found at S41 10.(A-E-F)(C+E)(G-B) E174 54.(E+F)(B-C-F)(2C+F)
You can check your answers for this puzzle on GeoChecker.com.
The cache is a 200ml sistema, with log book only.
