I think the FOBs only work in close proximity...so likely only on planet. So trying to find a planet where no one suspects you is ideal. But their tiny battle made a little noise so people went to check it out... and boom...FOB starts beeping. In the first episode he asked for a last location and the FOB didn't start beeping till he was on the planet of baby Yoda I believe.
I actually think I might have an explanation for this.
Since most of the fobs are for bail jumpers/smugglers/etc. I think we can probably safely assume that when you get arrested by the republic/empire/whoever you get implanted with a tracking thing.
So not everyone has them, just people who have at one point been 'in the system.'
Which is why, at this point, I'm roughly 100% sure baby Yoda is a clone. Implanting clones with some kind of tracking device would seem like a pretty obvious move. At some point Mando is going to have to remove it.
