[QUOTE="PhaseTech, post: 469521, member: 3149"] I'll try and simplify the technology part. Basically all Minelab PI machines are Multi Period Sensing, with a few tweaks along the way. SD Series - MPS GP Series - MPS + DVT GPX4000 - MPS + DVT with some digitization of circuitry. GPX4500 - a 4000 plus SETA (and other settings) GPX5000 - 2 new timings and some circuitry changes to make them perform at optimum. Many older coils particularly aftermarket would not work properly on the 5000. In some timings yes, but not all. The 5000 required a very tight tolerance on coils so aftermarket guys were quick to react and put out coils that would be 100% compatible. I pretty much stuck to Commander coils early on, and the green Minelab 18" Mono (2nd series) before the new flat wounds hit the market. [/QUOTE]
