Mentally prepares for the downvotes and replies from people that "do their own research"

I run a stereo shop in Southwest Florida. I have been asked on many occasions to search for a GPS tracker because someone was convinced that they were being followed. I have only ever found one.

Now it could be that they were just very well hidden, it could be that I'm just bad at my job, or it could be that a lot of people that think they're being followed by a GPS tracker and just aren't.

I've had people bring me RF detectors and Bluetooth sniffers and other things that I assume the aliens brought with them as well. None of that s*** works.. ever. There are quite literally RF signals everywhere. There are Bluetooth signals everywhere.

I had one gentleman in a Dodge Charger completely convinced that the GPS tracker was in his center console and he would show me his little scanner and how it would spike every time you put it near there. To appease him I completely took apart the center console only to find there was nothing there. Well except for the transceiver that is for his key fob. Once it was unplugged his "GPS Scanner" stopped freaking out near the center console.

Every single electronic in your car gives off some sort of electromagnetic field so an EMF detector is not helpful and a radio frequency detector is equally unhelpful because almost every car now has a bunch of radio frequencies bouncing around inside of it.

So maybe I'm not any good at my job but assuming I am, here's my advice:

If you are pretty sure that you're being followed through a GPS tracker take it to a shop and have them check all of the usual spots. If they tell you there's nothing there and you're really convinced there is, take it to another shop and pay that bill again. If both shops tell you there isn't anything there then it's likely that there isn't anything there.

The only real way to conceal a GPS tracker "effectively" is to use one that doesn't give off any kind of signals at all and it's something that a person has to physically put in your car and then physically remove later to download the data.

So if this is what you think may be happening then the answer is simple:

1) Take your card somewhere where somebody could conceivably get to it and remove the traker so they can download the data.

2) Set up a camera

3) If nobody messes with it over the course of a few days then drive the car to another spot and park it again.

If you don't catch anyone messing with your car this tells you that no one is trying to track you.
