On average, the typical GPS variance is about 3-10’ throughout the day. For that reason, we recommend you leave at least a 15-foot buffer zone between your boundary and any unsafe areas (like a road).
As long as you have the buffer in place, this boundary variation is no big deal for your dog. Why? Since SpotOn was developed with portability in mind, our training programs are focused on teaching your pup audible tones, not visual cues. Your pup will hear their first notification 10’ from the boundary, and once trained, this tone will remind the pup to retreat back safely within the boundaries of the contained area. This makes traveling with your dog a breeze and the occasional boundary shift practically unnoticeable for your pup.
