You need a journalist tape recorder. Dismantle the audio head and instead connect the ferrite, via preamp. You have here 2 versions. Treasure give great signal.

Dear firend Esteban, can you plase tell me were i can find a preamplifier and beep schematic, cause i want to make your Medium Distrance Treasure Locator.
Already have the tape recorder, ferrite and new oscilloscope and also digital signal generator to build and experiment with it.
Sorry for my english and i hope you can help me investigate with this simple circuit.
Kind regards
Nelson
