Thanks to everyones helpfull replies. BTW, I am using a Lowrance Globalmap100 I bought secondhand last year. MapDatum has been verified to be WGS84. Update:Most of the benchmarks around here have had thier Lat/Longs updated and verified by a local geocacher. Bad weather here lately, so I haven't been able to vist many of the local benchmarks. However, the one benchmark I was able to get to was 118 feet from where my GPSr said I should be. Earlier today I found the first part of a multi-cache... again 100+ feet from where my GPSr said it should be. So, I'll be trying the suggestion about clearing my track data, however I believe I will be just giving up and buying a second GPS. Perhaps one that is a little easier on the batteries, has WAAS, that I can attach to my bike, and connect to my computer. --Cam

So, what is this Pocket Queries that you extoll so much? And why are they worth it? --Cam

I've known about geocaching for a while, but I've only hunted 2 caches. The first one my GPS had me a good 60 feet off from the cache. The second one I haven't found yet, however, having been to the site, and having re-read all of the Logged Visits, I'm certain I know where it is, and its 100+ feet from where my GPS said it was. Both Caches have had no comments about Coords being off. So my question is: Should I expect this much discrepancy when hunting? If not, then what can I do to improve the accuracy of my GPS? It has been suggested that I might be able to calibrate my GPS by finding a National Survey Marker and telling the unit exactly where it is. Is this a good idea? Any advice? --Cam
