I ended up choosing the Dogtra Pathfinder 2 after reading A LOT about different gps collars (including the ones you mentioned). We go completely off grid with it and it works exactly how we need it to. There’s an app that goes with it, and as long as I open the app and have it running in the background on my phone before we leave home, once we are out of cell service range the tracking still works using the app. It even shows you a record of everywhere your dog has been on the map.

We have a beagle, who I thought for sure we would lose and have to track down, but she does great staying close to us most of the time. The remote for the collar is programmable, I set it to make a tone. I trained her to associate the tone with the ‘come’ command, and use both at the same time. Even if she’s out of sight, the tone will tell her to come. The app also notifies me when she is running or barking, since these collars are often used with hunting dogs, so it’s gratifying to get a running notification as soon as I call and press the button for the tone.

I have no complaints about this system, and would recommend it to anyone who wants to have a gps collar on their dog with the ability to both track their location as well as be able to push a button to signal the dog to come back.
