Z Mystery Cache

The cache is not at the stated co-ordinates, there is nothing there to help you find it.

This is my second puzzle. Its the basically the same as the first - but different; and a bit the other way round. Its harder than the first or maybe easier depending on how you look at it.  Hope that helps ?
