Correct. This is why there’s multiple in different locations. They’ll either have to spend enough time in place hunting for them that they’ll give up, without taking it or they’ll find the first one, or the second one and think they are good after destroying it or ditching it, and take off only to quickly discover there’s still more. And one would have to disassemble quite a bit to get to some of them.
If a thief wants something they’ll take it. Any prevention is just a deterrent to slow them down or discourage them.
I’m not saying it’s a full proof way to track or anything. But for $30/tracker with no monthly fee it’s easy peace of mind. I have them on my truck, buggy, camper, and generator. 1 iPhone can have up to 16 air tags linked to it.
