Why does my Garrett Metal Detector make erratic sounds or show erratic target ID?
- MmartinpughJul 28, 2025
If your Garrett Metal Detector is producing erratic sounds or the target ID cursor is moving erratically, ensure the searchcoil is securely connected and the coil cable is snugly wound around the stem. If you're indoors, be aware that electrical interference and metal in floors/walls can cause this. Also, check your proximity to power lines, fences, or other metal structures. Try adjusting the channel or reducing the sensitivity setting.
