  We argue that supersymmetric BPS states can act as efficient finite energy
probes of the moduli space geometry thanks to the attractor mechanism. We focus
on 4d $\mathcal{N}=2$ compactifications and capture aspects of the effective
field theory near the attractor values in terms of physical quantities far away
in moduli space. Furthermore, we illustrate how the standard distance in moduli
space can be related asymptotically to the black hole mass. We also compute a
measure of the resolution with which BPS black holes of a given mass can
distinguish far away points in the moduli space. The black hole probes may lead
to a deeper understanding of the Swampland constraints on the geometry of the
moduli space.
