So today’s the day.
You’re off on a fabulous adventure/ treasure hunt. You’ve packed your food, water and supplies in your back pack. You get your cache positions, lay down your route, and head off. You have a thoroughly fabulous day finding clues, scrambling about in the undergrowth, hiking over hills, crashing through woods, and … YESSSSS!! Cache Found.
Then back home, nice warm bath, yummy food and recap the delights of the day.
To make every geocaching venture that enjoyable and safe, and hopefully that successful, you need your GPS to do the following:
1. It must find it’s position quickly and easily.
When you switch on, the gps looks around, finds four or more positioning satellites and works out how far away they are. Using this information, it works out its own location.
It has a fair bit of work to do. And, as you can imagine, some GPS do this faster and better than others.
When geocaching, you want to be able to switch on your gps and see your position displayed almost immediately. You don’t want to have to find a rock to perch on and a long stick with which to wave your gps about, before it finds itself.
2. It must be able to accept the coordinates of the caches you are hunting for.
So you know where to aim.
3. It must hold unto it’s satellite lock, tightly.
It’s no good having your gps tell you it doesn’t know where you are, simply because you’ve walked under a tree, or a few clouds decide to make an appearance. You need to know that it will continue to guide you to the caches and back home.
4. It must give you information in a way that you find easy to understand.
You can have your position displayed on maps of varying detail, or just as a longitude/ latitude number.
5. It must guide you in ways that you find easy to follow.
Some gps just tell you the direction to take, others sketch a route, and others still can lay out your route in a 3-D, hello-holosuite kind of way.
6. It must be accurate.
Worst case, to get you within sight (10 – 15 feet) of the cache. Best case, to place you right on top of the cache.
7. It must be rugged and waterproof.
