Are in attendance any real-but-cheap tracking devices close to contained by "No Country for Old Men?"?

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 individuality uses throughout part of the picture. I remember back within the day contained by the Spiderman comics when Spidey would toss a "spideytracker" (or whatever) on a fleeing bad guy to shut in up with him next.

But then I remembered Science 101 class when I be told that the only radio transmitter/receiver combos that be small and cheap enough to use as a bit 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 highway, moving, etc., etc....

The question: do items similar to this really exist? Or was this only fiction? Or was it a device that really costs $10,000 or doesn`t matter what...?
