Hello treasure hunters! I'm new to this business, but I think a device (handheld detector) that looks for precious metals and gemstones could help standard metal detectors. You probably know this device, it has supersensitive antennas that can determine not only the depth of the treasure, but also position them, at what distance the treasure is from the device. And these portable devices are quite affordable. They save the hunter from unnecessary searches and unnecessary energy costs for digging out false targets. I think many people already know about these devices and use them productively, right?
