mediator will decay predominantly into light states, such as pions, muons, electrons, gammas and neutrinos. As they are produced in the decays of highly boosted mediators, these decay products will be tightly correlated with the direction to the original WIMP annihilation point, with a typical angular size $\theta_V \sim 1/\gamma_V$. While for charged particles this correlation can be reduced by the magnetic fields encountered on the way to the detector, the directionality of gammas and neutrinos is unaltered. Modern gamma ray telescopes enjoy an angular resolution much better than a degree, which may be exploited to enhance the gamma ray signal-to-background. In particular, a notable source of background to this signature is the generation of gamma rays via cosmic rays impinging on the Sun (see, [*e.g.*]{} [@Seckel; @Strong]). Such background gammas will typically display a much softer spectrum than gamma rays from mediator decays and will have no specific correlation with the solar center where most of the secluded WIMP annihilation is expected to take place. The main gain in sensitivity in detecting gammas from the decays of metastable mediators, as compared to a more conventional search for a highly-energetic neutrino signal, may come from the increase in efficiency.
