CM allows you to read the old logs, hints etc if you choose to tewll it to load them on your Palm.
Basically, you get a pocket query in GPX format as per your specification, you launch the PC application, you choose which caches you want on your Palm (I have had over 500 at one time for about 1.5Mb but that was just playing around.
When synced, Cachemate merges the caches you selected with any in its database, preseving your logs, updating old logs etc.
All CM fields are text that you can alter if you wish, so you can add, delete or change info o nyour Palm as you wish.
Caches can be imported or exported as Palm Memos to a simple template.
It will sort caches by distance from a cache, or from a position given by a GPS if you have acabe to link your palm to a GPSr
In all, very quick, very clever and very well done. Well wort hthe pitance it costs.
BTW I use a PalmIIIxe upgraded to Palm OS 4.1 and due to a Serial port crisis on the home PC I use a non-branded USB ot Serial converter that looks like a brick to upload data to my GPSr. It seems to work faultlessly.
