5000
Cache is not at posted coordinates (notice there isn't a scuba diving attribute?).
To commemorate my milestone of finding 5,000 caches, I've put out (yet another) puzzle cache. It's near (but not at) the location of my first find (sadly archived due to changes to the area).
To find where I've hidden it, work out what's special about 5,000 and solve the following puzzle:
The cache is at: S41 13.abc E174 51.xyz, where:
abc = ( 15th * 4th ) - 9th + ( ( 8th + 4th ) / 3rd )
xyz = ( 13th * 7th ) + ( 10th * 5th ) - 12th
GPS was a bit fuzzy at placement but there's detailed finding instructions in the certitude checker.
