Can someone explain the accuracy limitation of an ELT

ADFs not carried anymore in searching aircraft ?

Yes, the search aircraft will be guided right over the spot. They carry
special very directional antennas. The same antennas that can be carried by
hand by the search crews. The 12 mile or so is simply a place to start the
search. If the ELT signal is good, an airborne search can very quickly
narrow it down much further.
