Positron annihilation is perhaps one of the less well-known methods for measuring the Fermi surface. In this talk, I will explain how one can determine the Fermi surface topology of a metallic system using positrons, highlighting some of its advantages as well as its limitations. I will focus on materials where other probes (such as quantum oscillatory techniques or ARPES ) have not been so successful, as well as materials where the positron can provide unique information by virtue of where it chooses to annihilate. I will describe some recent measurements in the ferromagnetic shape-memory alloy Ni$_{2}$MnGa and in MnSi.
