Is this a joke? You have internet, it can't be that hard to find a Minelab diagram of the detector you are trying to pull that out of. Here's an idea: pay the $2600 to Minelab for the technology they developed and hell, I bet they'll even throw in the detector arms, coil, battery, and nifty plastic casing that encloses the part you are looking for, for free! That sounds like a great deal to me, and possibly exactly what you are looking for?
