Finding iPad without having find my iPhone set up?

I know apples find my iPhone can track your iPhone iPad iPod and computer if its set up. But that's only if its connected to a wireless or 3G network or turned on right?

What if you don't have find y iPhone set up? Can it be traced any way or do the authorities have a way of tracing it if its off?

Thanks, ps I have not lost anything yet just curious.

:) I'd say that that authorities probably have a way to find n ipad that's not set up with "find yor iPhone", but I'm pretty sure that it still needs Internet connection to work. Unless they go on google earth and zoom in really far… Hope I helped
Ps. An individual needs to have find your iPhone setup and Internet connection if they lose something
