I think you're best sticking with a world anchor, if you can. The anchor keeps a 3x3 chunk area loaded, whereas teleport tether is only one chunk. So unless your quarry is less than 16x16 and is completely within one chunk and doesn't cross any borders, it won't work. But it's likely that you cross chunks.

Like Spavid said, use the chunk grid option on the mini map to see where you're located.
