About

Underwater geocaching is a treasure hunting game where you use SCUBA gear and navigational techniques to hide and seek containers with other participants in the activity.

The cache is a brightly coloured container containing a logbook where you enter the date you found it and signs it. It also contains a treasure which you can take, provided you replace it with another treasure for the next cacher to find!


DO NOT ATTEMPT THESE CACHES UNLESS YOU ARE A QUALIFIED SCUBA DIVER. ALWAYS DIVE IN SAFETY AND WITHIN YOUR LIMITS!
