Nearby you will see a line of antennae overlooking the sea. The equipment is part of a system measuring sea surface currents and waves.
There are two sets of equipment, the other one is at Llanddulas, Clwyd.
Together they give a composite picture of what is physically happening on the sea surface at up to 50 miles away.
The information will ultimately be used to help with shoreline management of erosion and deposition.
This system is the only one of it's type in the UK.

The equipment has now been moves, including the fence, so a little more searching will be required to find the cache.
