Here's a less controversial topic, I hope. I have been using a Dogtra 1100NC on a long term loan and need to purchase my own collar soon. This is my first dog seriously training. She is doing Seasoned/Senior work and I'm planning on continuing for Finished and Master, don't know if she is a FT quality dog but I may give it a shot. I think I need something with the 1 mi range and was looking mostly at the TT Pro models or the Flyway, but would also consider a Dogtra. Any input from TT and Dogtra users out there?
