Review on Enhance Detection Accuracy with Klein Tools ET140 Non Destructive Detection by Dave Moody

Wet area detection behind the wall. Removed the drywall only to find the metal that probably caused it to shut down. I don't think this is unique to this brand but more due to the technology behind these moisture detectors that don't use probes. Before purchasing this item, I had a leak detection "professional" with a different brand. I bought this tool to confirm her findings only to have us both wrong.
