what is maximum detection distance and maximum detection depth of yours PLL4046 LRL ??
20 - 30 meters or more ?? about depth can detect big golden deposite 3-5 meters in soil ??
does your PLL4046 LRL detect "PHENOMENN" induced only by gold and silver or all other noble and non-noble metals in the soil ??
