A temporary fence is an additional assistance to protect the areas that you don't want the mower to enter.
You can always set up an off-limit zone via the app, yet in the following situations you might also need a temporary fence as a dual protection:
- The boundary is close to a pool that you don't want the mower to fall into under any circumstances.
- The boundary is close to a fence or bushes, thus the satellite signal is weak at that particular spot.
You can also consider using the VisionFence as dual protection, because the VisionFence has a good two-dimensional visual recognition ability, and through training with a large amount of data, it can distinguish grass from non-grass objects, so as to avoid hitting these objects.
