Various tests of the Golden Mask 4 Pro WD

This is a compilation of my previous tests. Test # 1-6 In this video I'm showing how the new Golden Mask 4 Pro WD metal detector is reacting to different (mostly silver) targets using various disc levels and two (8 kHz / 18 kHz) frequencies. This test is about sound. You may also want to see some trash targets like foil or pull tabs: https://www.youtube.com/watch?v=8xpmykxUi0U Test # 7-9 In this test I placed 2 small coins and a ring near an (unknown) iron object just to see how the detector reacts.
