Hi Margo,
 
I have only used an EM38 a few times, I usually prefer the RM15
resistivity meter, so I have little actual experience.  R. Berle Clay,
the Kentucky state archaeologist, has used one for years.  His email
address is  [log in to unmask]  Chuck Niquette, Nomi Greber and Rinita
Dalan are also quite experienced with the EM38.  Chuck Niquette can be
reached at [log in to unmask] but I don't know if Nomi or Ms. Dalan have
an email address.  Their addresses were listed in Archaeologists of the
Americas as:
 
Nomi Greber                   Rinita Dalan
17937 Sherrington Rd.         215 Lincoln
Shaker Heights, OH 44122      Edwardsville, IL  62025
 
Reagrding the proper sample interval, that is really a matter of what
you are trying to find.  If you could be more specific as to the goals
of the survey, I could make some suggestions.  Feel free to respond to
my home email address.
-Stephen-
