What is Geocaching all about then?

We enjoy Geocaching - a pastime using Sat Nav and the internet to find hidden items around town and country.

It's best described as a fun and educational recreational activity; a treasure hunt that uses a GPS receiver or smartphone + app to find, typically, a box with goodies in.  See the entry on Wikipedia for a full description.

micbinks geocaching statsHere at micbinks we contribute to the geocaching community on the global GPS cache hunt website: www.geocaching.com - check us out under our ID which is, of course, 'micbinks' - and we enjoy searching out locations both locally and when on holiday.

Geocaching can be environmentally friendly - 'cache-in trash-out' - where participants clear rubbish from the geocache area (like The Wombles?).  It's a family friendly pastime and healthy for both mind and body, what with all the walking/searching/thinking that's required.  And it's highly educational - knowledge of navigation, topography, land use, GPS, mapping and the grid system is gained (oh, and where the local pubs are!).  As an environmentally responsible pastime, accepted practice guidelines are published by the geocaching community.  Geocachers monitor PMR channel 2 or 8 to listen for other cachers who may happen to be in the area.

So how do you go Geocaching?
Our Sat Nav receiverFundamental to geocaching is owning a handheld Sat Nav receiver (details later), or smartphone with a suitable app, and having internet access to view Groundspeak's geocaching.com, the geocachers gateway website!  Although you can view geocache details and previous finders' logs on the site, registration as a basic member (free) is required to see cache coordinates.  Caches can be searched for by area, viewed in a list and located on the integrated Google Maps overlay.  Once you've read and noted some juicy caches you'd like to attempt (they have difficulty and terrain ratings) in your chosen area, just put the coordinates into your GPS receiver (or app) and you're off!  It's probably best to start with straightforward rural caches approached on foot or cycle as there's less people about (called muggles in geocache speak!) to contend with.

Searching out a geocacheFollow the electronic compass on your Sat Nav device, keeping in mind that, unless you have wings, you can't always navigate 'as the crow flies'.  When you get to within, say, 10 meters, start looking around for any clues as to where the geocache might be hidden.  It helps to keep in mind the cache container type you're looking for, description, previous finders' logs and, if needed, the additional hint.  This often gives it away with clues such as 'bottom of fence post', 'under seat', 'hole in wall', etc, so be careful not to spoil the fun!

Logging a geocache findWhen you've (hopefully!) found the cache, open the container and fill in the paper log with the date and your geocaching name.  Larger caches contain small items you can swap if you wish.  Seal the lid and carefully replace the geocache back where you found it, covering with sticks, stones, etc. ready for the next geocacher.  If you wish, take a photo of something interesting nearby, taking care that it doesn't give the hiding place away.

The final stage is to log your find(s) on geocaching.com: log in, browse to the relevant geocache page and add a sentence or two describing your find (try to make it interesting) plus upload your photo if you took one.  And you're done!

So who places geocaches in the first place?  Why, other geocachers of course!  Here's some we've placed:
GC1FCY1 - One, Two, Three, FORE!
GC1T6HC - Jack & Jill went up the hill...
GC1W156 - A Sussex High

Let's look at one of our geocache finds...

Now, if we haven't put you off(!), read on for more on Geocaching...

Cache types
A micro cache - 35mm film potThe most popular is the micro-cache, a 35mm film pot placed as a stand-alone cache.  An advancement on this is the multi-cache which necessitates finding a number of caches each giving a part GPS coordinate to note for the final cache coordinates.

Other geocaches require the solving of simple - or involved - clues such as noting dates on, say, a building, notice or gravestone then using these numbers to work out the coordinates by following a given formula.  Now this may sound like too much trouble, but once you've tried one you'll find it's quite straightforward and a lot of fun, especially for the kids.  Some can involve a trail of many caches!

A larger cache container containing swapsThe larger lunch box caches contain small items to swap, the idea is one item is taken and one left which is noted in the cache and website log.  Items thus travel from cache to cache, often great distances and overseas too.  The next stage on from this are Travel Bugs where particular items are tracked as they travel around the country - or the world!  Now, where's that tiny tatty teddy auntie gave me all those years ago...

Other types of geocaches include:
Mystery caches - puzzles that need to be solved to determine the coordinates.
Webcam cache - finder needs to capture a webcam shot of him/herself to log the find.
Earthcache - educational location that people can visit to view a unique geoscience feature on-the-ground.

Container types
The most common is the 35mm film pot, but they can vary from the very small nano with just enough room for a log strip, to a lunch box or even bucket sized containing swaps.  In many areas containers are put in a camouflaged ammo type bag to keep the rain out (and make them harder to spot!).  The smaller containers are sometimes magnetic so they can be attached to metal objects.  Nanos can be particularly challenging geocaches to find, the blighters!

Muggles – what are they then?
A muggle free area at the moment... One term you'll often come across is that of the dreaded muggle, a term derived from the Harry Potter movies.  A muggle is an innocent non-caching member of the public who may unknowingly thwart your attempt at locating a cache.  Most cachers try to avoid raising the suspicions of the public at large when looking for caches as there's a chance they may think a geocacher is up to no good.  A persistent muggle is the worst, one who just won't move from the location you wish to search, such as someone sitting on the park bench right where you suspect the cache may be.  Most frustrating!
Left. No muggles in sight - yet - along this disused railway cycle trail as Mike logs a find.

Look out for the (usually) helpful cachers trail when within spitting distance of the geocache you're searching out.  This provides tell-tale evidence that the geocache is nearby, such as downtrodden vegetation or unnaturally positioned stones.  But also be aware of a false cachers trail, indicating others have been looking... in the wrong place!

Let's look at some unusual geocaches we've found...

Geocache equipment and software
As a minimum you'll need a small handheld Sat Nav receiver and access to the internet.  For the cost conscious you can probably pick up a suitable Sat Nav device on ebay for less than 50; even new a suitable basic one is only around 100.  You can use your existing computer and internet to access the geocaching.com website to search out caches to attempt and to log your finds (or no finds!).  Use the waypoint download facility (eg. LOC file, send to GPS) to load the GPS coordinates directly into your Sat Nav.

A small digital camera is handy to take an interesting picture in the cache vicinity which can be uploaded when logging your find.  Be careful not to create a 'spoiler' and reveal the cache location though!  Other useful items to take are gardening gloves (for rummaging around all those prickly plants) and a poking stick as you'll never find one nearby when needed of course!

Mike logs yet another geocache findAn increasingly popular option is 'paperless caching' using a mobile device - a smartphone + geocaching app that does it all in one unit - Sat Nav, web access, camera, mapping - we've heard some even have a phone thrown in too!  This allows you to locate caches 'on the fly' in the field and log your finds straight-away (subject to Wi Fi or network coverage of course).  There's many applications available to assist, varying from the free to the rather pricey (some are listed below).  Groundspeak have an all-in-one app for a certain very popular mobile device and several cache info formats (premium membership required):
GPX file - file containing cache name, number, description, hint, logs and additional waypoints for a single geocache
Pocket Query (PQ) - single GPX file containing up to 500 geocaches

Post caching we like to look at our finds and breadcrumb trail by loading these from our Sat Nav device onto a user generated Google Earth overlay.

Geocaching has a social aspect too.  Apart from the social network provided by the website, many local groups of geocachers get together, say, once a month in a pub; automatic notification of upcoming local meets are given when logged into the website.

It's an international hobby with many overseas travellers finding and logging caches in countries they're visiting.  Expect to see log entries from visitors from abroad, particularly in popular tourist areas.  We've searched out some rather scenic caches in recent years while visiting Gower, the Cotswolds, Cornwall, Isle of Wight, Wiltshire, Kent Pembrokeshire, the Wye Valley and Dorset's Jurassic Coast.

Here's some 'guardians of the cache'...

Terminology
Like many hobbies, geocaching has its own language and abbreviations, here's a few common ones:

GPSr Global Positioning System receiver (AKA a Sat Nav device)
Spoiler - a give-a-way to the cache location, maybe a photo or text that's too specific
Stealth - trying not to draw too much attention to yourself while caching
SL - signed log
DNF - did not find
FTF - first to find
T4TC (or TFTC) - thanks for the cache
TNLN - took nothing left nothing
TB - Travel bug
CITO - cache in trash out
stickouflage - unusual pile of sticks covering a geocache
