Magnetic nanos are okay in the right place, but out in the countryside it is nice to find something bigger. The cache is hidden close to the paths from Polbeth to West Calder.
Magnets are always fun to play with. They have an almost magical life of their own, attracting steel, iron or another magnet. There are no swaps required here - if you would like to take a magnet, please do. Just don't drop the cache in the water! (otherwise the "may require wading" attribute will come into play)
