[Star Wars] if tracking a ship through hyperspace was impossible until the First Order discovered it, how did Boba Fett follow the Millenium Falcon to Cloud City?

Edit: Ok i think i figured it out: the tracker placed on the Falcon didnt track location, it tracked coordinates the ship's computer was calculating.

Bam!

Which begs the question: why didnt they use this type of tracker the whole time?

Han didn't use the hyperdrive, it was damaged. So Boba Fett knew he didn't leave the system, and just waited for the Imperials to leave so Han would show himself. Then he just casually followed him to Bespin.
