Gadgets Old And New At The Spy Store
on the old radio-based trackers. Back in the twentieth century, you could easily slip your tracking device into the mark’s pocket or stick it on his shoe, but when it came time to find his location, it wasn’t so simple. You were receiving a radio signal that told you the distance from the tracker but not the direction. You could drive around for quite a while before you worked out which way to go, and by that time the signal could be out of range.
A digital tracker with GPS transmits the actual map location to you, so it’s simplicity itself to find the target. The spy store even has one that’s integrated with a camera. You could stick this under someone’s bumper to find out where they’re going. The device is so small that it doesn’t have enough power to send you the camera footage, but the GPS signal makes it easy to keep track of the device and retrieve it later. This could be a dangerous gadget in the wrong hands. I’m glad I have no secrets to hide!
