HS-12 Signal Indicating Metal Detector Pinpointer
The HS-12 shows a signal reading rather than only alarming, so an operator can judge approximate distance to the target instead of guessing. It is rated IP68 to 30 m depth, detects in all 360 degrees, and reaches 5 to 6 cm on a one-yuan coin, with a choice of sound, vibration or both.
