gti 2500 metal detector tips
What is Metal Detector and how does it distinguish between metals? Metal Detector is an electronic device that detects the presence of a metal that is not liaising with it (due to radio waves and catches of secondary signals) and, when found, informs the operator of the fact (sound signal, arrow movement, etc.). The difference […]
