If the location of the core is inaccurate it may think it’s still outside a no-go zone even if it isn’t, I would be wary of using this as a “for sure” fix.
Hopefully they come out with per area PPVS settings soon, the “Drawing Max Travel Distance” is when you’re driving so you can set that much higher I’ve found, I have mine at ~100. I have my boundary set to ~70ft and in area set to max. I have a couple heavily wooded areas that still require checking a few times when it pauses waiting for GPS, and resuming to get the area completed. Those areas are pretty far from “danger zones” though.
Also I found if you set your speed to the slowest it allows it to spend more time in “good GPS” locations. It might also keep it’s own position a little more accurate too
If the HaLow isn’t working and the connection status only says 3 but never 2 then check your internet connection. I had a similar problem and I was going crazy only to find my ethernet cable was in but not snapped in so the connection was none to little. After fixing that connection, it has worked great and I have a very large and very difficult property.
its looking for help
