Prevention Pins show the locations in which your dog received fence feedback from the Halo Collar. You can choose how many recent Prevention Pins you would like to appear on your My Map screen. 

1. Open the Halo App
2. On the "My Map" screen, tap on the image that shows three stacked squares
   
3. You will be brought to the Map Settings menu
   
   
   
4. Under "Show Latest Fence Preventions", you can adjust the number of pins shown on the map, or disable this feature.

At this time, we do not have a feature to completely erase the prevention icons that appear on the map.
