No way. From looking at its size, it is just another lie in terms of GPS. The collar uses GSM networks for triangulation, GPS just kicks in passively to help a bit more (otherwise battery would constantly be empty if it has GPS LIVE tracking). So each time you read such things, replace the GPS with GSM, a wonder those companies can still get away with it, by constantly labeling it as GPS, the GPS function is very small and marginal. So, GSM, what does this mean? Prone to electro-magnetic interference, horrible in dense areas (your dog running into the woods, reception will be weak, especially if a not-even ground (sloped, hills, etc). Furthermore, the price is pathetic. The technology in there in today's world with the few extras and the R&D involved (has been around for ages), this is worth 50 bucks the most so if they'd sell it for 200 usd, I could sigh, but if I really wanted it, I would get it. But over 1000 bucks and a monthly subscription ????!!!!! No Way ! There are cheaper methods. So this is regarding the tracking.
As for Geo-Fencing only, there are cheaper methods out there just as effective if not better.
If you put a lot of value into tracking, you need a Garmin GPS tracker that also works with radiowave tracking (has no GSM included). The GPS will delay your dogs location to each 20-30 secs or so (otherwise battery runs dry in like 10 mins if you do live tracking) but you know where your dog is at, thus you let the radiowave tracker do the rest to help you get to him. But this is for hunters, or owners whose dogs run off easily after wild live etc, etc.
All GSM trackers I always had were useless. They never properly work when needed the most, a lot of inaccurate readings, overheating smart-phones, if you really must, get a proper GPS/Radio-Signal tracker, Garmin has them. But this, I recommend not.
Here is a more affordable solution by the best of the best in GPS technology, they also do non-GPS related products with their own independent monitoring devices, this as I recall is a more Geo-Fencing oriented product:
(Sorry for being so direct, I get upset at companies that keep saying GPS when it is actually GSM).
