I enetered the coordinates into my GPS for a new cache, but the map doesn match up with the actual location. What am I doing wrong?
Most likely the coordinates are in the wrong format or datum. See above question on converting format and make sure your GPSR uses WGS-84. There is, however, a slight variation in the Topozone maps when linked from the Geocaching site. The Topozone website uses NAD-27, a different coordinate datum.
