I posted this over a year ago and got a ton of positive response, so I wanted to repost as a courtesy. Here is an article on how to Geocache without a GPS unit. Though I am addicted to my Garmin, in the very beginning, I hunted many without a unit.. until I was hooked enough to spend the money on equipment. For those of you out there interested in trying the sport out, without an investment, here are some tips to get you started.. until you're able to find the right GPS unit for you.
