What gps devices do you use to do your geocaching? If you use a smart phone, which and what software? Why? ---------------- Personally I have 3 devices that I play with when looking for treasure. a Smart phone, and 2 GPS with paperless geocaching. I started using a Motorola Droid and the software c:geo found on the market. I have since read that this may be a violation of geocaching.com terms and I will be looking more into it. I do find this to be the easiest method of geocaching at least when I have a 3g connection. The second unit I picked up is a Magellan Explorist GC. This is sold as a geocaching device, not necessarily a GPS unit. It does of course act like a GPS but lacks a lot of the features that a "real" gps unit would have. It does however have a massive 10,000 waypoint storage. I feel this unit is great for just geocaching or weekend camping trips. You can set waypoints and navigate back to them with relative ease, but without the ability to add new maps and no sd card slot, your pretty much just following arrows. This unit cost around $150. Finally I picked up a Earthmate pn-40. Its a full feature GPS device with paperless geocaching added on. I really like this unit. It has the ability to take waypoints/caches from a sdcard or directly from geocaching.com. It stores waypoints in sets of 1000, which I find nice because I can simply have caches stored based on city or area I am in. it also has the ability to use topo maps with a added feature of using satellite image overlays which helps it act a bit more like my droid. They cost a few bucks depending on how much are your trying to cover, but its well worth it. This unit was also around $150.
