[QUOTE="Roscoe, post: 230934, member: 1615"] Aussiefarmer, Every new minelab PI detector has been made to find gold in flogged patches over its predecessor. The reason for this is that every nugget in the ground has it own unique signature, this signature is effected by its size, shape, purity, thickness etc. etc. This is why PI detectors have timings and the more timings you have the more versatile the detectors is on a wide range of nuggets (signatures). The SDC has a very fast timing in Normal and a slower timing/ pulse in Salt mode. The 4500 has multiple timing options for a broad range of nugget types and soil conditions. The 4500 will pick up sub gram gold but not at the frequency as the SDC 2300 will. But, the 4500 can be run with bigger coils and timings to suit ground and nugget types. The 4500 is a much more versatile unit over the GP3000 and the 4500 allows the use of mono coils better in hot ground, which the GP3000 really struggles. I hope this helps. :) [/QUOTE]
