What would be the top brand of collar if you were not going to go with Tri-Tronics. I have had some issues with Tri-Tronics lately and their customer service has not been the same since the switch to Garmin in my experience. I am not looking to get into all of that. I would just like to hear what brands would be a top choice if Tri-Tronics was out of the picture. I know there is Dogtra, Sportdog and D.T. Systems that I mainly see advertisements for. Are there other worthy brands that i have seen? I have done zero research and have no experience with any of them as I have always been a TT guy. What would are some suggestions for other ways to go? I was using the TT Flyway G3.
