We read some interesting articles about geocaching and thought it may be something that we could do together (and would get us out of the house). So in early July 2005, after putting new batteries into our old Magellan 4000 and printing out some caches near our house, we confidently headed out to try to find some treasure! This page describes what we found while geocaching, and offers some tips and hints for the new Geocacher.
The first thing we found out was that our old Magellan 4000 was not really made for Geocaching. It worked OK when we used it for hiking (to mark our campsite so we could find our way back if we got lost), but with only 2 receivers it constantly lost the fix on the satellites, and didn't work under tree cover or near buildings. We also figured out that we were using the wrong navigation screen, which made things even harder. After unsuccessfully searching for two different caches, we tried a third one that we found without the "help" of the 4000.
Global Positioning System receiver (GPSr)
After our experience with our old Magellan 4000 GPSr we decided to check out the more "modern" GPSr's on the market. We found out that all of the latest models (Summer 2005) had at least 12 receivers. We also found they were a lot less expensive then when we purchased the Magellan. After looking at the equipment offered by Garmin, Lowrance, and Magellan we decided to get the least expensive model that had had at least 12 receivers.
Lowrance iFinder Go
At $75 delivered to our house, the Go certainly doesn't have all of the fancy features of the upper end models, but it did offer:
Some features that upper end models have that we have found can be useful:
After getting the Go, we also figured out which navigation screen to use.
Navigating with your GPSr
When we turn on our GPSr's we get a screen that tells you where you are - nice, but not helpful when attempting to find a cache. To hunt for a cache you need to switch to a screen that "points" to a waypoint (the cache), and tells you how far you have to go until you get there.
Here's a sample navigation screen that show you need to go 1.71 miles North to reach the waypoint "Home". If "Home" has the coordinates of your cache you would simply have to walk (or drive) 1.71 miles due north to arrive at the cache location. Note that the navigation screen only points toward the cache when you are moving, so you need to actually move in order for the arrow to point in the correct direction. In this example, the cache is 1.71 miles to the North, but you would have to start walking to find out if North is straight ahead, to the left, right, etc.
There are just a couple more basic GPSr configuration items you need to check. You need configure your GPSr so it's using the correct map datum (WGS84 is common), and the correct coordinate system (Degrees Minutes.Hundreds of Minutes is common - for example: 33° 19.322). You'll have to check your manual or search through the menus to configure it properly.
Using our new GPSr
Once we configured our GPSr and loaded in the coordinates for the two caches we couldn't find, we headed out again. This time it was easy. The GPSr never lost the fix and the navigation screen almost pointed directly to the cache containers!
Finding a series of caches
If you entered multiple cache locations into your GPSr (by the keyboard or downloaded them through a computer interface), you can easily go from one cache to the next by using the "Find Closest" function of your GPSr. The "Find Closest" function will look at all of your Waypoints and list them in order from the closest to the furthest away. For example, if you use the "Find Closest" function right after you find a cache, the cache you just found will be first in the list, the next cache would be 2nd, etc.
Where are the caches?
There are a number of Geocaching pages on the Internet, but we primarily use geocaching.com. The site provides a lot of information about Geocaching, like: its history, how to get started, location of caches around the world, forums, etc. The next sections give you quick overview how to use the geocaching.com site to get and log caches.
Get an account
To actually get the coordinates for caches you need to sign up for a free account. To create an account you need to click on the log in hyperlink located at the site. If you are just starting out you probably don't need to sign up for a Premium Membership until you decide you actually like Geocaching and want the additional features the you get with a Premium Membership.
Get local cache information
Once you get your account you'll probably want to see what kind of caches are near where you live. After you log in you can look on their Home Page and under "Search for caches..." you can enter your zip code. When you select Go you'll get a page something like this:
The "A" column shows you how far and what direction the cache is from your location. The "B" column tells you what kind of cache it at the location. There are Traditional caches (), Multi-Caches (), Mystery/Puzzle caches (), and Virtual caches (). The "C" column shows you how hard it is to find the cache (Difficulty of find/Difficulty of terrain) and how big the cache is at the location (). The "D" column is the link to the cache description (which includes the coordinates of the cache).
How to read a cache page
For your first cache you probably want to pick one that is near your location, is a Traditional cache, is easy to find and the terrain is easy (1/1), and is large (the bigger the red dot the better). The cache "Alto" meets all of these requirements except it's a small/micro cache. If you click on Alto you should see something like this:
The "A" points to the coordinates you would enter into your GPSr. You can read the description, any hints, and the log entries, then go out and try to find it. Once you go out and find it you would log your visit by coming back to this page and selecting "log your visit" ("B").
That's it for the basics. If you want to ask any questions you can sign up for a Forum account (select FORUMS on geocaching.com and you'll go here to create an account). You can also surf the Internet for other sites.
Other resources on the Internet
In addition to geocaching.com we also use other Web pages to help with caching.
If you want to get an idea of the cache location you can copy the coordinates from the cache page and paste it into Google Maps. Here's what Alto looks like in Google Maps:
It looks like the cache is located at the Northwest corner of Alta Dr. and Elevado Ave.
If you were interested in the contour lines (because you are out in the wilderness), you could use the Topo Map on Lostoutdoors.com to get another view. Here's Alto from Lostoutdoors.com:
The blue dot is the location of the cache.
