My Magellan Explorist 500 gets lost even more than I do!
I edited the track log to get the worst of the wild ramblings out, but many remain.
(Magellan track logs look like this:
$PMGNTRK,2119.808,N,15749.331,W,00462,M,193125.06,A,,211009*66
$PMGNTRK,2119.816,N,15749.318,W,00463,M,193151.07,A,,211009*61
$PMGNTRK,2119.825,N,15749.314,W,00477,M,193217.05,A,,211009*6B
$PMGNTRK,2119.834,N,15749.309,W,00485,M,193240.07,A,,211009*6A
$PMGNTRK,2119.837,N,15749.294,W,00481,M,193349.06,A,,211009*61
Not that easy for senile people to edit!

Distance and Time profiles here. This shows tracks of my last three hikes here (as off 2009) on one map.
