Bill,

You may have discovered the reason for the error. Maybe I marked the waypoint too soon after turning the GPS on. I did wait for the satellites to lock though.

Chris and Bill,

I do agree a person can navigate with topographical maps alone. I also feel giving away the compass is taking away a valuable tool. I think a GPS is useless for a person that ventures off trails.

I think three people expressed my feelings about topo maps. They are fun.
