Sometimes after recording a zone boundary, the boundary can appear incorrect on the map.
This can happen if you don't have sub-meter GPS precision when recording a boundary or if you walk too fast when setting up the boundaries.
It's better to redo the zone boundaries rather than mapping the course all over again. When you set a new boundary on an existing zone, it overwrites the old one.
Make sure the GPS indicator, in the bottom left corner of the screen, has a green badge that says 9 or higher. This is the number of GPS satellites the POGO currently sees. If you have less than 9, your GPS location may not be completely accurate.
- Always keep the POGO on with a view of the sky throughout the day, or at least until all sampling is completed for a particular session of sampling all zones. We have seen many users mount the POGO in a length of 2” PVC irrigation pipe to their cart. It makes for a nice transport system and protects the POGO very well.
- Walk at a leisurely pace when setting your boundary. Tap the Get GPS button about every one to two seconds when walking the perimeter.
- When taking soil samples or when recording the position of a property feature (sprinkler, valve, drain, etc.), pause a moment or two before taking the sample to allow the precision of the POGO's GPS to be as accurate as possible.
- Even if you are showing 9 or more satellites, interference from wires, trees, buildings, and the time of day can show variance as the position of satellites can skew a bit in the sky. These are normal variations in GPS are not due to the performance of the POGO.
If you follow the above tips, you should have sub-meter accuracy at nearly all times.
To redo a recorded boundary, go to Property Features in the app and then Zone. Tap the zone you wish to redo a boundary for.
