I tried a number of pet trackers and none match up to the accuracy and quality of the petTracer one. My cat went never goes missing and very rarely goes off for longer than 2hrs max. We recently moved and purchased a couple fo trackers, the one he had on just didn't;t seem to maintain a signal or pin point his location. The worst happened when he disappeared for 13hrs and when we tried to locate him there was nothing, you obviously think the worst. We saw PetTracer and he did the same, I loaded him and cold not believe how accurate it was in locating him. I think he was also shocked to hear my voice call his name when he strayed further than he usually does.
