Geocaching: the world's largest modern-day treasure hunt
Geo coins, bugs and 'swag' are some of the treasures one can find in a global adventure known as geocaching.
Every cache or treasure has a name and consist of trinkets and toys, known in geocaching technology as swag (stuff we all get).
The location of the items is posted online and participants use their GPS to hunt for or hide them; and there are about 7000 treasures hidden around South Africa alone.
The pastime took off in South Africa in 2000 and according to Silvia Ludwig, an avid geocacher (who even owns her online Geocaching merchandise store), it is easy to get hooked on the pastime.
It considered a game or sport. People hide containers of various sizes and shapes. There is also a log sheet inside and the bigger containers will have little trinkets and goodies in them. You basically load the GPS co-ordinates and you get as close as possible to ground zero and look for the container.Silvia Ludwig, Geocache enthusiast
Participants must register and set up a user name online and the experience is recorded on the Geocache website.
Ludwig says that the most exciting thing about geocaching is that it takes people to places that they may not have known existed before.
She and her family have hidden over 200 geo caches since starting the hobby in 2008.
