Two alternative alert ways
There is a power switch to choose between audible tone and vibration. It's easy and convenient to operate the metal detector.
Loosen the screw of the battery door and install a 9V battery ( 9V battery not include ).
Hold the arm pole and change the three-position switch from "off" to "alarm". The green LED power light will be on and a short beep can be heard.
Use a coin to test the metal detector function. When the coin passes the detector an alarm or vibration will occur.
Sensitivity tuning: adjust the sensitivity in the "sensitivity tuning hole" on the right of the metal detector with a small screwdriver. Adjust clockwise to increase the sensitivity and anticlockwise to reduce the sensitivity.
Low voltage alarm: when you turn on the power switch of the metal detector but hear continuous alarm, it means the battery voltage is low and should be replaced.
