Review on 🔒 Enhanced UniquExceptional UHMD Portable Security Metal Detector in Black by Chuck Shapiro

We had to remove the oil tank and I had to mark the sprinkler system. I usually did this by running it and finding the gurgling, but I had to keep the system dry for easier repair after the tank was exhumed. Although most heads are plastic, with the metal detector's increased sensitivity, I was able to easily find the metal springs inside the sprinkler head housings. Did the trick for exactly what I needed it for.
