I only just heard of geocaching 72 hours ago, and already I think I feel an addiction coming on. The concept seems clear, but when looking for equipment, I am flooded with information about fishing, camping, etc. What I want to know is what type of GPS I need to start this adventure. I don't have a ton of money, and I am eager to start...TODAY. I would order a system, but don't know what I need, nor do I have the patience to wait for the mail to come. Anyone feel my pain and have some useful advice? I will appreciate it all. Thanks, and happy hunting.
