What is the difference between the Tri-tronics 80C and the 80M ?

QUESTION: What is the difference between the Tri-tronics Sport 80C and the 80M – hard to see the difference while cruising the descriptions.

ANSWER: The C has 12 levels of continuous stimulation and 6 levels of momentary.The M has 6 levels of continuous stimulation and 12 levels of momentary. I prefer the C over the M. This is a much better collar than the Companion.  It has a 1/2 mile range compared to the 200 yards you had on the Companion and it does have a tone on the dial feature. Please let me know if you have any questions.  We do appreciate your business.Thanks,Steve Snell
