Geocache Description:


This cache was placed by special forces using a mini-submarine. The cache is not at the coordinates above. The published coordinates are the last known postion of the mini-sub before it dived below the Waitemata harbour and travelled to the cache site. There was not enough time to get a gps fix at the cache location due to the speedy and covert nature of the cache hiding operation. However we have been able to obtain the output of the mini-subs dead reckoning system. Your mission, should you wish to accept it, is to calculate the route taken by the mini-sub and hence find the cache location.

Your solution may not be 100% accurate and GPS reception at the site is poor, but if you find the correct beach the hint will lead you to the cache.
