[QUOTE="XLOOX, post: 676588, member: 16174"] There is one thing that I never fully understood and that is why some PI detectors are considered good for Big Deep gold ( SD2200, 7000Z, GPX5000) and others are considered Small Shallow gold detectors ( SDC2300, GPX6000 & now AF-E1500). I get that for small gold you need a small coil & very small pulse delay timing and for big deep gold you need a big coil and slightly longer pulse delay but naively I assume that any detector that can separate the target signal from the ground signal for 0.1g at 100mm could do the same for 100g at 1m, if it had a bigger coil. It seems that is not the case else the SDC & 6000 should be great deep detectors when coupled with +18" round coils but no-none is even making coils that big for them. So there must be more to what it takes to make a good deep gold detector than sensitive electronics and a big coil but I dunno what the other differences are . Anyone have any knowledge on this topic? [/QUOTE]
