Systems and methods for detecting metal clips inserted within a portion of a body of a patient are disclosed herein. In one embodiment, a clip detector assembly includes a detector having a ferrous member, a transmitting coil around the ferrous member and configured to induce a current in the metal clip, and a receiving coil around the ferrous member and configured to receive a magnetic field generated by the current induced in the metal clip. The assembly can further include a control circuit having a band-pass filter configured to pass electrical signals induced by the magnetic field from the receiving coil that are within at most 35 kHz of a resonance frequency of the metal clip. The assembly still further includes a user notification component configured to alert a user to a location of the metal clip.
