A listening device for pinpointing water leakages, which includes a manually operated rod having a handle at one end for manually positioning of the listening device. An acoustic pick-up apparatus is mounted on the other end of the rod, and it comprises a ceramic audio tone transducer which is operatively connected to an amplifier-receiver which has a level meter on which visual leak signals may be seen. The acoustic pick-up apparatus is also connected to a head phone set to allow hearing of the leaks. The transducer includes a brass diaphragm directly attached to a threaded stud for mounting in the rod.
