Moisture sensor
John Thompson purchased the device to locate moisture that seeps through carpets but found that it can be used to detect lifelines too. Where there’s moisture, the device sounds. Where the wood has died, the machine is silent. See his demonstration on a large olive below.

Marty says
They make very similar equipment for measuring the moisture content of wood when doing woodworking. Most full service woodworking stores will have one or more models available.
