Hi guys, I hope this topic is not dead yet. I bought a used gpx 5000, but my results are not the best. I tried a couple of settings that I found on the Internet, the results are somewhat better, but I'm not satisfied. The device will not "penetrate" through rock thicker than 40 cm. (tested on 8g of natural iron that I found during the search). I use the classic mono coil that comes with the device upon purchase. I bought the device with the intention of searching on large natural stones. It is a hidden treasure and not natural 24k gold. Do you have any recommendations for settings that would help me go deeper with the device. Or the device cannot penetrate the stone (like through the ground)?
