Looking at an e-collar for my newer pooch - seeing all these new collars with GPS and wondering if that’s worth the extra money? I don’t really PLAN to have him roam like that, but never know with a young dog. Like all the options that the Garmin Alpha + Tri tronics collar offers, especially that you can add another collar, but is there another decent option, something I should look to. Really would like a collar that does vibrate, tone, and the stim - but I could probably be persuaded otherwise.
