    Why does my Garrett ACE 350 Metal Detector make erratic sounds?
    • B
      brettbuchananAug 3, 2025
      Erratic sounds or Target ID cursor movement on your Garrett Metal Detector can be due to several factors: excessive electrical interference and metal in floors/walls (if indoors), a loose searchcoil connection, high sensitivity settings, or proximity to metal structures or other detectors. To resolve this: be mindful of the indoor environment, ensure the searchcoil is securely connected and the cable is snugly wound, reduce the sensitivity setting, and move away from other metal detectors or structures.

      If your Garrett Metal Detector isn't finding specific targets, ensure you're using the correct mode for the type of hunting you're doing. If hunting for coins, use COINS mode to eliminate undesirable targets. You can also use ZERO mode, which detects all metal targets to ensure desired targets are present.

    Why does the Target ID Cursor bounce on my Garrett Metal Detector?
    • R
      Robert RogersAug 18, 2025
      A bouncing Target ID Cursor on your Garrett Metal Detector can occur if you've found a trash target, a good target isn't parallel to the searchcoil, there are junk targets near the good target, or large, flat pieces of iron are present. Try scanning from different directions until your Target ID Cursor becomes more stable.
