Excellent
Before getting a GPS tracker, I was initially concerned about its acurracy in remote locations. Spytec turned out to be much better than anticipated. It was so accurate on the map that it could distiguish the difference between it being on the vehicle in the driveway or it being 20 feet away in the house while charging in the house. I was very impressed. If I had to put a range on the accuracy, I would say it was always within 0-5 feet from what you could see on the map.
