Comparing the PawGuard 820 and 830 GPS Wireless Dog Fences
Quick answer: The PawGuard 820 and PawGuard 830 are both outdoor GPS wireless dog fences with an adjustable circular boundary of 25 to 999 yards (about 23 to 914 metres), an IPX7 waterproof collar, and no subscription, SIM card or Wi-Fi requirement. The main difference: the 830 uses an upgraded multi-satellite positioning chip (GPS, BeiDou and Galileo) for stronger signal and better interference resistance, while the 820 is the straightforward, great-value choice for open gardens and fields.

Which one should you choose?
Choose the PawGuard 820 if you want reliable GPS containment for an open garden, paddock or field at the best price. Its two-level protection system (warning first, correction only if your dog keeps going) makes training straightforward, and it fits most medium and large breeds.
Choose the PawGuard 830 if your property has patchier sky view or you want maximum positioning accuracy. Its upgraded chip locks onto three satellite networks (GPS, BeiDou and Galileo) and adds a 3–5 yard buffer to smooth out normal GPS drift, with a clear audible warning roughly 3 yards before the boundary line.
What they have in common
