You said the "Can" for does. There are a number of different cans each making their own sounds. Contact, Call Out, Estrus etc.....Primos by themselves have three or four different calls for different times of the year and situations. Hunters Specialties makes about the same amount. They (Using the right one) can be used throughout the year, hunting season or not, from contact to breeding. You have to determine which one fits the occasion. Here is a web page explaining the different sounds. DOE SOUNDS And here is a page at Bass Pro showing the different "Cans" just from Primos. Doe CallsI hope this helps.
