You have that backward, the s one has 6 meters, the d one doesn't, the g is 
the ones with the updates to it, the later models. I don't think you can 
upgrade a 570s or 570 d to an sg or dg but really the changes are more nice 
to have things rather than things you'd miss. I don't remember what they are 
exactly as I sold my 570DG several years ago and didn't use it for a while 
before that since I had my ts-2000 but as I recall there were some menu 
items I never changed anyway.
