Metal Detecting Demo Kit allows you to learn the sound for each metal sample.
Out kit include a bottle cap, can tab, nail, quarter, dime, nickel, penny.
In an open area relatively free of trash, toss the targets onto the ground spacing them far enough apart to allow for sweeping and pinpointing. Sweep the detector coil over one target at a time, listening for the sound as the search coil is directly over the target. The Detect Screen and audio response will give you detailed information about the target ID>
