Be careful asking for an opinion here,'cause we all have one Mine would be that the tracking collar would be useful for hound hunters, but if you need one for you pudlepointer your doing something different than the rest of us. Get a training collar, and learn how to use it properly. I use tritronics, because they're made in the good 'ol USA, but they are basically all the same.
They are two different tools for different purposes. I don't think it is an either or situation, but what tool do you need.
I think the astro is a sweet set up. Yea it's another collar on your dog, but if you have a big runner they will not only tell you where your dog is, but where its been. How many miles traveled, elevation gained and lossed. All useful information in my mind.
i can't figure what you'd need a gps tracking collar on a bird dog for. a hound dog running bears or lions yeah...but a pointing dog?i'd exchange it and get an e-collar.
