  We present a completely localized solution to the problem of entanglement
degradation in non-inertial frames. A two mode squeezed state is considered
from the viewpoint of two observers, Alice (inertial) and Rob (accelerated),
and a model of localized projective detection is used to study the amount of
entanglement that they are able to extract from the initial state. The Unruh
vacuum noise plays only a minor role in the degradation process. The dominant
source of degradation is a mode mismatch between the mode of the squeezed state
Rob observes and the mode he is able to detect from his accelerated frame.
Leakage of the initial mode through Rob's horizon places a limit on his ability
to fully measure the state, leading to an inevitable degradation of
entanglement that even in principle cannot be corrected by changing the
hardware design of his detector.
