Geocaching FAQs

Geocaching (pronounced geo-cashing) is a worldwide game of hiding and seeking treasure. A geocacher can place a geocache anywhere in the world, pinpoint its location using GPS technology and then share the geocache’s existence and location online. Anyone with a GPS unit can then try to locate the geocache. Be sure to check with the landowner before placing a geocache. Some areas, like Sacramento County Parks, have specific policies regarding geocaching, and permits may be required.

A GPS unit is an electronic device that can determine your approximate location (within 6 - 20 feet) on the planet. Coordinates are normally given in Latitude and Longitude. You can use the device to navigate from your current location to another location. Some devices have their own maps, built-in electronic compasses, and voice navigation, depending on the complexity of the device.

Each GPS receiver is a computer that receives signals broadcast from GPS satellites. A receiver needs to read signals from at least three satellites at a time to calculate its general location by a process called trilateration.

With signals from four satellites, a GPS receiver can get a more accurate fix that includes altitude and the exact time, as well as latitude and longitude. The more satellite signals the receiver reads, the more accurate the position it reports to you. 

Sacramento County Regional Parks requires a permit to place a geocache within County Parks. This permit can be downloaded at www.sacparks.net.

If you take something from the cache, leave something of equal or greater value. Write about your find in the cache logbook. Log your experience at www.geocaching.com.

In its simplest form, a cache always contains a logbook. The logbook contains information from the owner of the cache, notes from visitors and can contain much valuable, rewarding, and entertaining information. In smaller caches, a logsheet may be used.

Larger caches may contain a logbook and any number of more or less valuable items. These items turn the cache into a true treasure hunt. You never know what the owner or other visitors of the cache may have left there for you to enjoy. Remember, if you take something, it is only fair for you to leave something in return. It is recommended that items in a cache be individually packaged in a clear, zipped plastic bag to protect them from the elements.

A geocoin is a special coin created by individuals or groups of geocachers as a kind of signature item or calling card. Each geocoin is assigned a unique tracking ID which allows them to travel from geocache to geocache or to be passed amongst friends, picking up stories along the way. 

Because each geocoin is assigned a unique tracking number its progress can be tracked online through logs which the finder posts. There are different types of logs which can be made on a geocoin's personal home page, whether for virtually picking up or dropping off the coin, or simply for "discovering" the coin. You’ll have the opportunity to share your thoughts on the geocoin page and to upload any photos associated with it. In addition, by logging a geocoin your online collection will reflect that you found that particular coin. 

The most common question on etiquette relates to what to do if you find a Geocoin. Keep it? Move it to another geocache? The answer always depends on the goal its owner has set for it. Usually the best way to find the answer to these questions is to visit the geocoin’s personal home page and read the description it contains. If there is a theme or special instructions from the owner you should do your best to adhere to the geocoin’s goal, or send an email to the owner for more clarification.

If you create your own series of geocoins and wish to prevent people from selling them, it is recommended you activate all of your coins on Geocaching.com before they leave your possession. This gives you a claim to ownership and, once reported, allows us to deactivate the coin at your request. If you have given any geocoins away which have not been activated, we consider it to be a transfer of ownership and cannot intervene. Think ahead!
