RedDog,
No GPS expert by far - but I did use some of my ginseng profits from last season to buy me a Garmin GPSmap 60CSx.
I played around with it some this past winter and was impressed with the device.
I pulled down all of Middle TN on topo maps and have that loaded so now anywhere I am hunting I will have the lay of the land in my pocket for easy viewing. Can also mark spots (nice patch) and easily relocate it later on.
That is about all I plan to do with one, mark patches, or places where I am planting seng, and for topo map reference.
The Garmin looks like it will do all of that and more and has a realy nice compas built in.
