Hi, when i go to old stone house, where is floor ground, my detector react to stone walls, where dont have iron or similar things. Can you help me to reduce it to get better stability?
What is the detector doing? Maybe try a smaller coil? That can help with EMI and high iron areas. The Garrett 5x8 Pro coil is a excellent choice. Mine never comes off.
So, the stock coil si not good?
