I just purchased a dogtra 1803 used. It only had 2 collars, the gentleman had lost the other collar. I have found another collar for this setup but don't know if it will work with my setup or if I will have to have something done to make it work. Anyone who knows if it will work or what I will have to do to make it work, please let me know if I should buy the extra collar or not?

Thank you,
Steven
