fabing half doors
I use a Garmin Legend. I bought it off of eBay for around $125, I think. You can get GPS units that will work fine for geocaching for as low as $80 if you look around. Basically, you'll be better off with a unit that you can link to your computer and that has extra memory for mapping software, but that's not really necessary. You can enter the waypoints by hand, but it saves time and errors if you can download them directly from the computer. Have fun! Though I haven't really found any yet that I needed the Jeep, I know in other parts of the country, there are caches hidden specifically to be found using 4wd vehicles. You'll be amazed at some of the places you never knew existed once you start looking for caches!
