Geocaching 101

What is Geocaching?

Geocaching (pronounced geo CASH ing) is a high-tech form of "treasure" hunting played around the world. A cache is the object that is hidden; geocaching is the act of finding a cache, utilizing a GPS and exact coordinates from the internet. A geocacher can hide a cache somewhere in a public area and then post the cache coordinates online at www.geocaching.com. Anyone with a GPS can then try to locate the cache.

Personally, I'm a fan because it is a fun way to explore the world around me. I have found so many parks, trails, cool views, historical sites, etc that I never would have known even existed otherwise. It can be done alone or in big groups, and provides a new adventure every time.


How do you begin?

1. Purchase a GPS, or befriend someone who owns own. :)
2. Visit the geocaching website.
3. Register for a free account. Be sure to pick a cool username, as this will be what everyone sees.
4. Click "Hide & Seek a Cache."
5. You can search for caches by either typing in your address or zip code, or putting in your coordinates.
   
6. Choose any geocache from the list and click on its name.
7. Make sure to look at the terrain and difficulty level, and plan your adventure based on your preferences and time limits.
   
8. Enter the coordinates of the geocache into your GPS unit.
9. Follow the GPS directions to the cache area and start searching. Good luck in this stage!
10. Sign the logbook and return the geocache to its original location.
11. Log your find in your online account. Please share your geocaching stories and photos!

Tips on picking a GPS:
Below is the list of things to consider, taken directly off of the geocaching website. From my experience I would suggest looking for the following: ability to add additional SD memory cards, ability to download maps, long lasting rechargeable batteries, and easy operating instructions. And recently I've noticed that a colour screen is handy too...though not at all necessary.

• Basemap. This is highly recommended. The additional cost is marginal, and the increase in the equipment's usefulness is substantial. Driving directions to the area near a cache can be incredibly useful, so consider this feature in a higher end device.

• Channels. Most GPS units today now have 12 parallel channels. Channels help to acquire GPS satellite signals faster and more accurately. If you are looking at older GPS devices, consider models built after 1997. Older, single-channel receivers are much slower and may not be as accurate.
• External antenna jack. With new GPS devices this has become less important since the newer chips are sensitive enough to acquire signal inside a vehicle. However, it is not always possible to obtain good satellite coverage through a front windshield; this is when an external antenna can help. Even backpackers will benefit from the ability to safely store the receiver inside a pack with an antenna attached to backpack shoulder straps. It can also help outdoor use in places, like heavy tree cover, where signals are weak.
• Interface jack. If you are using the receiver with a computer, be sure that it includes an interface cable so you can quickly load maps and waypoints onto your device. Newer GPS units often support USB while older devices generally have serial attachments. If you purchase an older GPS device and have a newer computer, you may need to purchase a USB to serial port adapter as well. If you own a Mac, you should check to ensure that it supports the Mac operating system.
• Memory. This is used to load detailed topographic maps, street-level maps, or additional waypoints into the receiver. Detailed maps can use a great deal of memory on your device. Consider internal storage capacity. Higher end devices also usually accept a memory card for additional storage.
• Power source. It is preferable to have a device that can support external power, like a cigarette lighter power cable. Due to the power requirements the device should support standard batteries (AA or AAA) for easy replacement on the trail. Lithium batteries are recommended for newer GPS models to ensure a longer battery life, and power geocachers should consider rechargeable batteries.
• Rocker keypad or touchscreen. Using a receiver without a rocker keypad is like using a computer without a mouse. Some newer GPS units have touchscreens which helps immensely when navigating using the maps.
• Screen size. For visual ease of operation, use a device with the largest screen that can be realistically carried. Screen size is measured diagonally. Color is great and helps define map features and a backlight is important, although both features burn additional battery power. A screen protector is important in preventing scratches out on the trail.
• Waterproof. Sooner or later your device will get submerged. Get a device that is at least water-resistant, although an IPX7 designation is preferred. An IPX7 designation means the GPS case can withstand accidental immersion in one meter of water for up to 30 minutes. Plastic bags and boxes are also recommended for added protection.
• Geocaching Features. An increasing number of higher end GPS devices now have functionality specifically created for geocaching that can store all the information from Pocket Queries. Some will also store field notes to help you log your caches after a hunt.

Keep in mind:
As I mentioned before, make sure to take note of the terrain and difficulty level, as well as the size of the cache. Pack everything you are going to need, such as water, food, a pen, trinkets for trading, etc.

Now grab some friends and start your exploration. HAVE FUN!
