The utility model relates to a concealed wire detection circuit and a visual hand-held portable hunting instrument. The concealed wire detection circuit comprises a magnetic head coil, an induction circuit and a state display circuit. The magnetic head coil is connected with the induction circuit, and the magnetic head coil is used for inducing an alternating magnetic field generated when alternating current is introduced into a dark line, converting the alternating magnetic field into a voltage signal and outputting the voltage signal to the induction circuit; the induction circuit is connected with the state display circuit, the induction circuit is used for converting the voltage signal into a binary signal, and the state display circuit is used for displaying the binary signal. According to the utility model, based on the principle that when the current in the electrified cable is fixed, the closer the magnetic head coil is to the electrified wire, the stronger the induced voltage is, the magnetic head co
