What is Geocaching?
Geocaching is an entertaining adventure game for gps users. Participating in a cache hunt is a good way to take advantage of the wonderful features and capability of a gps unit. The basic idea is to have individuals and organizations set up caches all over the world and share the locations of these caches on the internet. GPS users can then use the location coordinates to find the caches. Once found, a cache may provide the visitor with a wide variety of rewards. All the visitor is asked to do is if they get something they should try to leave something for the cache.
How do you pronounce Geocaching?
You pronounce it Geo-cashing, like cashing a check.
Are there any other names for Geocaching?
The GPS Stash Hunt, Global Positioning Stash hunt is interchangable. Geocaching has become the standard for the game, however.
The word Geocaching broken out is GEO for geography, and CACHING for the process of hiding a cache. A cache in computer terms is information usually stored in memory to make it faster to retrieve, but the term is also used in hiking/camping as a hiding place for concealing and preserving provisions.
So what's the big deal? You gave me the coordinates so I know where it is. Seems pretty easy.
It is deceptively easy. It's one thing to see where an item is, it's a totally different story to actually get there.
What is a GPS device?
A GPS unit is a electronic device that can determine your approximate location (within around 6-20 feet) on the planet. Coordinates are normally given in Latitude and Longitude. You can use the unit to navigate from your current location to another location. Some units have their own maps, built-in electronic compasses, voice navigation, depending on the complexity of the device.
How do GPS devices work?
If you're interested in finding more information about Global Positioning Systems, check out GPS: The New Navigation by PBS. They have an excellent Shockwave and/or web page that explains how GPS works!
So if I have a GPS unit, someone can track where I am (and where I'm going)?
No! GPS devices do not actually broadcast your location. The satellites using radio frequencies actually broadcast their own position. Your GPS unit takes that information to figure out where you are (triangulation).
Unless you have a tracking system implanted by aliens, you should be safe from the satellites above. As an extra precaution, however, you can put aluminum foil on your head to deflect the "gamma" beams.
How much does a GPS unit cost, and where can I get one?
GPS Units can range from $100 to $1000 depending on the kind of capabilities you are looking for. The author uses a Garmin eTrex , which runs for around $100, and can get you to within 20 feet of any geocache (depending on the location). The next step is one with a built-in electronic compass, has topographic maps, more memory, etc.
You can usually find GPS units at any boat supply store, and some camping stores keep GPS units on hand. You can also purchase them online through Amazon.com and camping supply companies.
A good, basic GPS unit is the Garmin eTrex GPS, or Magellan GPS 315.
How do I use a GPS unit for Geocaching?

What are the rules in Geocaching?
Geocaching is a relatively new phenomenon. Therefore, the rules are very simple:
Where you place a cache is up to you.

What is usually in a cache?
A cache can come in many forms but the first item should always be the logbook. In its simplest form a cache can be just a logbook and nothing else. The logbook contains information from the founder of the cache and notes from the cache's visitors. The logbook can contain much valuable, rewarding, and entertaining information. A logbook might contain information about nearby attractions, coordinates to other unpublished caches, and even jokes written by visitors. If you get some information from a logbook you should give some back. At the very least you can leave the date and time you visited the cache.
Larger caches may consist of a waterproof plastic bucket placed tastefully within the local terrain. The bucket will contain the 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 founder or other visitors of the cache may have left there for you to enjoy. Remember, if you take something, its only fair for you to leave something in return. Items in a bucket cache could be: Maps, books, software, hardware, CD's, videos, pictures, money, jewelry, tickets, antiques, tools, games, etc. It is recommended that items in a bucket cache be individually packaged in a clear zipped plastic bag to protect them.
What shouldn't be in a cache?
Use your common sense in most cases. Explosives, ammo, knives, drugs, and alcohol shouldn't be placed in a cache. Respect the local laws. All ages of people hide and seek caches, so use some thought before placing an item into a cache.
Food items are ALWAYS a BAD IDEA. Animals have better noses than humans, and in some cases caches have been chewed through and destroyed because of food items in a cache. Please do not put food in a cache.
Where are caches found?
The location of a cache can be very entertaining indeed. As many say, location, location, location! The location of a cache demonstrates the founder's skill and possibly even daring. A cache located on the side of a rocky cliff accessible only by rock climbing equipment may be hard to find. An underwater cache may only be accessed by scuba. Other caches may require long difficult hiking, orienteering, and special equipment to get to. Caches may be located in cities both above and below ground, inside and outside buildings. The skillful placement of a small logbook in an urban environment may be quite challenging to find even with the accuracy of a gps. That little logbook may have a hundred dollar bill in it or a map to greater treasure. It could even contain clues or riddles to solve that may lead to other caches. Rich people could have fun with their money by making lucrative caches that could be better than winning the lottery when you find it. Just hope that the person that found the cache just before you left a real big prize!
Can I move a cache once I find it?
Don't move the cache! Responsible cache owners often check on their caches and would be alarmed to discover that it is missing.
Are there any variations in the game?
YES! We strongly encourage it, actually. Geocaching is a game that constantly reinvents itself, and the rules are very flexible. If you have a new idea on how to place a cache, or a new game using GPS units, we'd love to hear about it.
Some examples -
How long do caches exist?
It all depends on the location of the cache and its impact on the environment and the surrounding areas. Caches could be permanent, or temporary. It's up to the cache owner to periodically inspect the cache and the area to ensure that impact is minimal, if not nonexistant. When you find a cache, it's always a good idea to let the cache owner know the condition as well.
Periodically, Geocaching.com will review each cache to ensure that everything is still current. We cannot guarantee that a cache will exist at any given time, but we'll do our best to ensure the list is as current as possible.
If you do find that a cache is missing/defaced, please let the cache owner know as soon as possible!
If I post a new cache, how long does it take to be listed on the web site?
Because each cache is reviewed by a volunteer, it may take up to 2 days to have your cache posted to the web site. Usually it takes much much less time - but be patient! Someone will review your cache shortly. It does take longer on the weekends since we receive a larger volume of caches during this time.
Does Geocaching.com (or a volunteer) physically check the cache before publishing it?
We wish! We'd love to head out to all those countries and states to check on each and every cache to ensure that they are placed properly. Based on the growth of the sport, however, this would be impossible. If you're not sure about a cache, wait for someone else to check on it and report back to the site.
Before a cache is posted, volunteers check the page for inaccuracies, bad coordinates, and appropriateness before posting the cache to the site.
What do I do if I find out that a cache has gone missing?
If you visit a cache location and the cache is missing, always make sure to log the cache as "not found" on the web site so the cache owner knows. If you notice that the logs show an unusual number of "not found" logs, please inform this web site so we can check on the cache page. The cache can be temporarily disabled so the cache owner can check in on it. Sometimes, though rarely, when the cache owner cannot be contacted we can either allow folks to adopt the cache or have the cache removed completely from the site. We rely a lot on the geocaching community to let us know the status of caches in their area.
Do you have an FRS/PMR channel to find out if other Geocachers are in the area?
Yes. The community has decided on channel 2 as the primary for both FRS and PMR, and 12 as the alternate FRS (Family Radio Service) channel and 8 for the alternate PMR (Europe). FRS and PMR radios are longer distance walkie talkies, like the Motorola Talkabout.
