UPDATE: Check out my hands on Garmin nuvi 500 review to read about a nuvi with paperless geocaching ability built-in.
Geocaching is an awesome sport, that gets technology enthusiasts (and often their kids) outdoors, albeit with a gadget in their hands!
A handheld GPS designed for outdoor use is the best tool for this high-tech treasure hunt, but many GPS enthusiasts only have a car unit. Fortunately for those of you with a Garmin nuvi, a method has been developed to allow you to give the sport a try without investing in any more equipment.
A member of Groundspeak, geocaching.com's message board, has put together a tutorial on paperless geocaching with a Garmin nuvi. By paperless, this means that you can hunt for a geocache without having to print out cache descriptions, logs, etc. I haven't tried this yet with my nuvi, but from what others are saying, it works quite well.
I do have a couple of caveats for those who wish to try it:
- Your nuvi is a fragile device, and even if you don't drop it (touch screen down) on a rock, remember -- it's not waterproof. A ziplock baggy offers some protection when the environment is a little moist, though I wouldn't rely on that in rain.
- Unlike handheld GPS recievers, your Garmin nuvi doesn't have a compass screen to point the way to a cache. Still, the tutorial walks you through how to get around this, and it's a great way to try out the sport.
There's a discussion / support thread at Groundspeak.
Thanks to Mike for reminding me about this.
