At Max react to the stone

[fostes]

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?

Try turning down the sensitivity, or, if the iron signals are at a certain point, notch out that point or try ground balancing on the hot rock and see if that clears it up. Switching to a smaller coil sometimes helps too. Good luck!

Try All Metal mode and turn sensitivity down. Practice on a test target to see how low you can set it. If it's like the AT GOLD the sensitivity in All Metal can be set much lower than in the DISC modes.
