Caches can be grouped in three categories – with and without a paper log, and events. A BIT Cache is a laminated card with a QR code, similar to Munzee.
Smaller containers are more common in urban areas because they can be more easily hidden.By May 6, 2000, it had been found twice and logged once (by Mike Teague of Vancouver, Washington).According to Dave Ulmer's message, this cache was a black plastic bucket that was partially buried and contained software, videos, books, food, money, and a slingshot. The activity was originally referred to as GPS stash hunt or gpsstashing.For the traditional geocache, a geocacher will place a waterproof container containing a log book (with pen or pencil) and trade items or trackables, then record the cache's coordinates.These coordinates, along with other details of the location, are posted on a listing site (see list of some sites below).Geocachers are free to take objects (except the logbook, pencil, or stamp) from the cache in exchange for leaving something of similar or higher value.
Aside from the logbook, common cache contents are unusual coins or currency, small toys, ornamental buttons, CDs, or books.
This was changed shortly after the original hide when it was suggested in the gpsstash e Group that "stash" could have negative connotations and the term geocaching was adopted.
Over time, a variety of different hide-and-seek-type activities have been created or abandoned, so that "geocaching" now may refer to hiding and seeking containers, or locations or information without containers.
Examples of goals are to be placed in a certain cache a long distance from home, or to travel to a certain country, or to travel faster and farther than other hitchhikers in a race.
Less common trends are site-specific information pages about the historic significance of the site, types of trees, birds in the area or other such information.
The geocacher enters the date they found it and signs it with their established code name, in order to prove that they found it.
