We have a new player on the field in the form of AlgoForce and their new E1500 detector. One thing that is not getting as much attention as I would expect from a PI - full range target conductivity id. From the owners manual: "For experienced PI users accustomed to estimating nugget size from audio cues, the AlgoForce E1500 can also help to estimate size or conductivity through its stable conductive target ID (0-99), even in highly mineralized soils. High single frequency VLF detectors typi
