Harbour Point - Part 3

We headed back to Irvine Beach Park again today to try to finally find the Harbour Point cache. I've already tried to find this twice, the first time on my own and the second with the full Super Collector clan but on both occasions we failed to find it. Today, armed with some pretty clear hints from the CO we all headed back for another go.

This cache is a puzzle where you have to collect information then apply it to a formula in order to work out the final coordinates of the cache container. Luckily all the information for this one is in the same place and we already knew where GZ was and had had it confirmed by two different people (including Chenks the CO).

Back at the GZ we headed straight for the location where we knew the cache to be hidden. But where was it? We'd been told by the CO that it was "well hidden" and he wasn't kidding. Despite knowing pretty much exactly where it was it still took us a few minutes to find.
