i'm not sure what geocaching ready means, but i know that on my magellan explorist 500 i can put the location of the geo cache plus some notes and stuff... maybe that's what they mean. and BTW, at beachcamera.com they've got the 500 for sale for only 175, free shipping, and the 10 dollar offer for mapsend topo 3d... another 6 or 7 dollars for the lithium-ion battery from ebay and you're set, for less than 200 bucks. GL with your shopping.
