As a starting geocacher I was looking for software that could help me to have all information I wanted in my Palm instead of carrying piles of printed sheets around that were old the following day. The Netherlands is not a very big country as you might know, but it is stuffed ( and I mean really stuffed) with geocaches, the west of the country (the South Wing of the Randstad) in particular.
The program comes with cmconvert that converts the gpx-files you get from geocaching.com to a Palm database used by CacheMate. From then you can carry all information: cache description, but also logs from others that were there before you and (still coded, but with one button decoding build in!) hints and a page to write down your own logging.
For only 8 US$ you are ready to go on your way. With, or without a handheld GPS, because CacheNav can show you the way too! With a cable or bluetooth connected gps connected to your Palm. Try it if you are into Palm OS!
There has been Pocket PC (PPC) version for almost a year now. (I have tried, but never liked PPC.)
(Brian, I did borrow you animated gif, without asking. I hope you don’t mind ;-) )
