Please note that this cache is NOT at ground level and wellies aren't sufficient.
The cache host will reveal itself as you get closer to it.
When at GZ please don't remove the copper wire, its there to help you reassemble the host after signing the log. I have added a photograph so you are aware of what you will be confronted with.
Pull downwards all 4 of the blue pipes to be able to retrieve the cache itself. Sign the log and reassemble the host to as you found it, then the next finder will have the 'wow' factor.
If the cache log sheet is not signed, then your log will be deleted.
Regarding GC9VVCO. You don't need a boat to retrieve the final coords. If you require another hint then please go to GC97TAK.
