Are there any real-but-cheap tracking devices like in “No Country for Old Men?”?

Neo G asked:


So I’m watching that Coen Brother’s movie, “No Country for Old Men” with a friend of mine, and a big plot device is a tracking device (transmitter and receiver) that a character uses throughout part of the film. I remember back in the day in the Spiderman comics when Spidey would toss a “spideytracker” (or whatever) on a fleeing bad guy to catch up with him later.

But then I remembered Science 101 class when I was told that the only radio transmitter/receiver combos that were small and cheap enough to use as a little walkie-talkie tracking device required direct pointing and/or line-of-site. Today’s GPS devices admittedly work around that, but that doesn’t explain the anachronism of this magical 1980s tiny cell-phone sized transmitter/receiver that worked through entire buildings, off of highways, moving, etc., etc….

The question: do items like this really exist? Or was this just fiction? Or was it a device that really costs $10,000 or whatever…?
