Following a compass is a real job, but following a (mirrored) sighting compass can be quite accurate.I don't at present but am thinking about it for gridding out sites to mark where I've been. Right now I use a compass and printouts from Google Earth to do this. I've been working a huge field off and on for about 4 years, and I would forget if I didn't log well. GE and a compass are good tools for this, but I think a GPS which can output kml (most do) would be faster. I just haven't gotten around to it yet, but it should work well for gridding large sites.
Hello. I use the built in GPS on my CTX 3030 to mark general area for hot spots or the area where very a nice item was found. It is a handy feature on the Minelab.Does anyone use a GPS in metal detecting? How do you use it? Do you use it to plot where you've been or just create waypoints of finds?
