I doubt that unless you were an early beta tester. Oct.2003 was when I got started and that was one of the first in this part of the country.

I do agree they work,and work 99% of the time with unbelievable accuracy. I just pulled into a field today that I quit on last Thursday and the trac was so close I could not see any reason to shift track. I think RTK is really not needed for most midwest row crop situations.
