Thank you, gentlemen. You've confirmed what I suspected. I tend toward "lagging edge" technology, but sometimes the lag is just too much.
If I could find an Etrex Legend or Vista HCX, I'd grab it. Can't seem to find a GPSMAP 6X that I can afford. REI had a 60cs for $130; gone before I could order it.
I'll keep looking and learning.
