Geocaching 101: How to find your first cache

by Carolyn K. director, Hoagies' Gifted Education Page

What is Geocaching?

According to the Geocaching.com website, Geocaching is "a worldwide game of hiding and seeking treasure."  For a great video and other introductory material, visit their Getting Started page.

Our definition is a little different.  While geocaching truly is a world-wide game, there is little treasure involved, unless you find old fast-food toys to be treasure.  And though they're sometimes frustrating, the most common sized geocache around here is the infamous "micro," which is too small to hide any treasure in at all.  Step back, though, and you'll see that geocaching is just the kind of fun that gifted minds enjoy.

We call geocaching a world-wide game of hide-and-seek.  Someone hides a cache, a small, medium or large hidden box for you to find, or defines a location that you need to visit and take a photo of or provide some information about to prove you were at the right spot.  That person or team makes up a set of clues that include the latitude and longitude of the location... which sounds like a giveaway clue, but that location is often just the starting place for your search.  Last, the cache information is posted on the Geocaching.com website, and it becomes available to everyone who wants to try and find the cache.

Geocaching has a lot going for it.  First, it is a means of getting the computer-addict off the computer and out of doors.  Yes, that includes me - the ultimate computer-addicted mom, as well as our kids.  And it doesn't matter if you live in the city, the suburbs or out in the boonies, there are probably geocaches near you.  Second, geocaching is free. While it's best to have some kind of GPS device, you can get started Geocaching with just a computer and Google Maps.  And when you get a chance, upgrade to an inexpensive Premium Membership to the Geocaching website... you'll jave access to special "premium member" caches, learn about new caches immediately upon publication, be able to get travel routes full of caches for your road trips, and more.

Geocaching is also a game you can play when you travel.  We've hunted caches in Dallas, Seattle and Inner Harbor Baltimore, among other places.  With 1.1 million caches placed around the world in the first ten years, Geocaching is a great way to find new and interesting places in cities and towns you think you know, and to enjoy places that are brand new to you, at home and abroad.  Though we haven't personally had a chance, we have friends caching in Australia, and our geocoins traveling to Hawaii, Canada, Scotland and Germany.

Which brings up another new term: geocoin.  Geocoins and Travel Bugs are trackable items that are sometimes included in a

You will need to learn a few new acronyms for Geocaching.  When you are FTF a cache that's just another MKH, you can TNLN, but be sure to SL and tell the CO TFTC.  See Geocaching Acronyms and Terms (below) for translations of these and other acronyms you'll encounter.

How do I get started?

The first thing you need to do is create a free account at Geocaching.com.  Pick a caching name and a password, and create your account.  You'll need to give a valid e-mail address, but fear not.  Geocaching.com does not spam, and you can turn off any newsletters or announcements whenever you would like.  Validate your account by clicking on the e-mail you receive, and you're ready to go. 

Once you're logged in on the Geocaching.com website, you'll want to Hide & Seek a Cache. You can seek a cache by address, zip code, state or country, or by keyword, GC code, or the username of the geocacher who hid or found the cache.  I like using the address feature if I know where I'm going, either using the exact street address, or just the city and state I'm searching.  When you click "Go" you'll receive a list of caches in the vicinity, with the closest caches listed first.  The compass shows the direction from the location you entered to the cache.  There's a check mark if you've already found the cache.  Icons show what kind of cache it is, as well as any trackables currently reported in the cache.

I am a visual/spatial person, and I much prefer maps over lists of words, so the first thing I do on any cache list is click on with Google Maps.  If you click the Google Maps link here, you'll get a map of north Seattle, the original home of Geocaching.  But when you click on those words on your cache list, you will see all the caches on the list overlaid on a Google map of your area. 

Which cache should I pick first?

When you're looking at the map, you can click on a cache icon to learn a few details about it.  Look for a cache with low difficulty and terrain ratings; 1 or 1.5 are good ratings for a first cache.  At the same time, look at the cache size.  Caches come in size micro, small, medium, large, or unidentified.  Unidentified can mean it is a virtual or earth cache, or for some reason the cache owner (CO) doesn't want you to know the size.  Micros can be tricky to find, so you might want to start with a small or medium cache.

When you're looking at the detail, you can click on the Name of the cache to bring up a page of details. There you'll get all the clues the CO provided, plus a list of all the logs already recorded for that cache.  Make sure the most recent logs are not Did Not Find (DNF), or you may be looking for a missing cache.  If you find yourself struggling in the search, click on the link to read ALL the logs for hints.  Even though each geocacher may think they haven't given anything away, the combination of comments often gives extra hints beyond what the CO originally posted.

In that detailed description, you will find the latitude and longitude of the location of the cache.  You'll need to enter these into your GPS, or paste them into Google Maps to find the location of the cache.  Google Maps is a great way to get started and to find caches located in the city, near the edges of parks, and other locations that are open to the sky.  But you won't be able to find a cache in the woods without a GPS device.  But don't give up if you don't have a handheld GPS; many automobile GPS devices have a way to enter coordinates, and a battery so you can take the GPS with you into the woods.

When you get to Ground Zero (GZ), the coordinates of the cache location, you'll need to use the hints found in the name and description of the cache to locate the actual cache container.

I can't find the cache...

Sometimes caches are hard to find.  The first thing to do when you can't find a cache is to go back and check the cache description page.  Have the last 5 loggers found the cache?  Was the last one recent?  If not, the cache may (or may not) be missing.  If the cache was last found, reread the description.  What hints are in the description? ...in the title? ...in the logs? 

Sometimes our GPS just does not want to settle down and give us an accurate reading, especially in the city with tall buildings all around, or in the woods under the canopy of trees.  In these cases, we've found a good old fashioned compass and triangulation are our best tools.  Walk away from the place you suspect, and get about .1 to .2 miles away.  Then take a reading on your GPS, and use your compass to locate the line that goes in the direction specified. You'll need to make a note of where that line goes; we often do this by having our caching partner stand in a line with several obvious trees or landmarks.  Walk around a ways, and take a second reading, and see where those two lines cross. That's the most likely place for the cache to be located.

In this day and age of Google and Google Maps, we sometimes opt for a Google Maps sighting rather than compass triangulation.  Go back to your computer and type the latitude and longitude of the cache into Google Maps.  Then zoom in as far as you can, to get an idea where the cache is located from the map.  This sometimes tells us that, in spite of triangulation, the readings our GPS is getting here under the wooded canopy are just too erratic and the cache is really... over there.

If you have a very old GPS device like our sailboat GPS receiver from the 1980's, it may only get you within about .1 or even .01 miles of the cache.  That's not close enough!  If this happens with your GPS, consider comparing the actual cache coordinates to the coordinates of your current location.  You will find that you learn a great deal more about how to spot which direction is North just by watching the sun in the sky, and you'll get a much better idea of where the cache is as you move in closer and closer to the cache coordinates.

If all else fails and you have spent far too long on a 1/1 or 1.5/1.5 cache, the best thing we've found is to walk away.  Go home, and come back another day.  You might gain new insight by being away, or you might take that break to contact the Cache Owner (CO) for a clue.  Either way, a little sleep and fresh eyes (or fresh clues) sometimes makes finding the cache a whole lot easier.

I found it!  Now what?

With cache in hand, be sure to sign the log sheet or log book in the cache, and rehide it as well as you found it, or better if it seems to be out of place.  Then when you get back to your computer, visit the Geocaching.com page for that cache and click on "log your visit" to record that you've found the cache.  Then look around the site, and pick another cache to find!

Here are a few things I wish I knew when I was searching for those first few caches.  First, the "skirt" at the bottom of the light post in the parking lot lifts up, and this is a common location for a cache.  This hint will save you the hours we spent over several days looking for our first "micro" cache at a Burger King... before we knew those skirts lifted.  Second, look for "just another pile of sticks."  Cachers love to hide ammo cans and other large cache containers in the woods, under a pile of sticks. Third, know that caches may be hidden inside things, and drawn out with an attached fishing line.  Inside the knots in a tree or inside a metal fence post is a great place to hide a cache.  Visit Cacheboxstore to see some very unusual cache containers.

Another goal for geocachers is to be the First to Find (FTF) a newly placed geocache.  Premium Members get instant notification when a new geocache is published in their, but sometimes even free members can get lucky and be the FTF.  And the FTF gets recognition on the cache's page, and often receives a small token.  We received a ready-to-place bison tube with log for our FTF; we've seen other FTF prizes that include an unregistered geocoin or travel bug, a gold dollar, or a gift card to a local fast food restaurant.  You never know what you'll get as the FTF!

You can place your own geocache!  Read how to hide a geocache and the Cache Listing Requirements and Guidelines before you select your cache location.  Find a waterproof container; geocachers often use Lock & Lock brand containers or recycled ammo cans for medium size cache containers, recycled plastic medicine bottles for small containers, or 35mm film canisters or bison tubes for micro containers.  Be sure to use Google Maps to double check your GPS readings for your new cache, and then report a new cache.  Your cache will be reviewed and published (if approved) within 2 days, and folks will race to see who will be the FTF!

Geocoins and Travel Bugs

Now that you're caching, the next thing you might like to do is put some trackables into circulation.  Trackables run $4-15, and each come with a unique ID number that is trackable on the Geocaching.com website under Trackables.  Geocoins tend to travel by themselves, while Travel Bugs tend to attach themselves to an object to be tracked.  We've seen Travel Bugs on a wine bottle cork from Germany, a plush Zebra bookmark from England, and a turtle keychain from Washington state.  And our daughter attached a Travel Bug to a Koosh Turtle that she tracks as it travels the world. 

We started a pair of Travel Bugs in Seattle to race home to Philadelphia; so far one is in Montana and one made it all the way to Kansas, in 10 months time.  Some of our favorite trackables so far are our geocoins, which have found their way all over the world.  Tracking them is an exercise in geography and fun!  For a list of online stores that sell geocoins, including some very inexpensive coins and travel bugs, visit Geocaching.

Geocaching Events!

It's great fun to get together at geocaching events in your area.  Nationally in the U.S. there's the annual mega-event, GeoWoodstock, for geocachers of all ages to share and celebrate their caching, coins, and more.  Next summer's (2011) GeoWoodstock event can be found here: GeoWoodstock. 

There are plenty of smaller local events, nearly always family gatherings at restaurants or parks.  Come join your fellow geocachers... you may (or may not) be surprised at how many gifted children and adults you'll find there!  At events, you can make new friends and trade caching stories, swap trackables, arrange caching runs together, and learn about great places for your favorite kind of caches, whether you're looking for more 1/1 (easy) caches or a place to accomplish your first century, finding 100 caches in a single day. 

Also at events you'll often find drawings and geocaching coins and supplies for sale, ideas for creating your own camouflaged caches, and

I've found a few geocaches with Google Maps and I want to buy a GPS. Which one should I get?

Everyone has an opinion on GPS devices, but the reviews tell the tale.  And so does a T-shirt I saw recently, which proclaimed "Get Garmin or Get Lost."  It's true, Garmin GPS devices are overall the most popular for geocaching, and if the reviews are to be believed, for automobile and other GPS uses, too.  Features you might be interested in for your GPS include...

While we're discussing features, here's one feature you do NOT want to find in a GPS... a "Geocaching ready" GPS.  While this type of unit sounds ideal, with the names and locations of all the geocaches in the U.S. today already installed, the problem is that it's just those geocaches that existed in the U.S. on a specific day: the day it was programmed.  To add caches, you'll need to buy an extra-cost cable and extra-cost subscription to the data.  Caches are added daily... remember, there are already 1.2 million active caches worldwide in only 10 years!  Just within a mile of our home in the last two months, there have been more than 2 dozen new caches posted.  And at the same time, caches have been muggled, washed away, or removed for other reasons.  Don't limit yourself by purchasing a GPS that only has a fixed set of geocaches installed.

Can I use my Smart Phone instead of a GPS?

Are you considering a smart phone?  Then you might not need a GPS at all.  The iPhone and Droid phones seem to be the most commonly used smart phones for geocaching.

Have an iPhone?  You guessed it... there's an app for that!  Groundspeak's Geocaching iPhone Application lets you geocache using only your iPhone.  The how-to pages warn, however, that the iPhone's location ability is not as sharp as many GPS devices and even other smart phones.  If you have an older (pre-3) iPhone, the phone uses it's network towers rather than a GPS chip to triangulate your location.  You may have to look a little harder, or you can use the Geocaching.com Google Map feature to zoom in and get a bird's-eye view of the location of the cache you seek.  Here's a great tutorial for Geocaching with an iPhone: Free Family Fun.

Try my new favorite Droid geocaching app... c:geo!  c:geo works with the GPS Status app, so download both apps from the Android Marketplace and go caching!  You can search for nearby caches, read the details, locate on the map or by compass, and even log the cache once you've found it.

Or try the first Android geocaching app, GeoBeagle, which also works with GPS Status.  Download the apps and you're off!  Neither of these Droid apps is an "official" Groundspeak Geocaching app; the official app is still in the "rumor" stage.  I'm sure we have great things to look forward to, but in the meantime, c:geo and GeoBeagle are a great Droid geocaching option.

Because the Android apps work with GPS chip in Droid phones, Droid geocaching apps are as accurate as your handheld GPS.  Enjoy the geocaching fun wherever you find yourself, without taking along any extra gear!

If you have a smart phone from AT&T or Sprint, or a  Blackberry or Nokia smart phone, you might be able to use Geocache Navigator.  Visit Geocache Navigator to see if your phone is supported. 

Welcome to Geocaching!

Welcome to the sport of geocaching.  But be careful... it's addictive!  Soon you'll find yourself out night-caching or rushing to be FTF on a newly placed cache, hiding your own caches or going for a caching streak - at least one cache a day for as many days as you can!.  Don't forget, Premium Membership to the Geocaching website can help with these goals and more.
