[QUOTE="steelPHASE, post: 451911, member: 13488"] Its extremely unlikely you will be able to get it to run with a Double D coil as per the 7000. Besides trying to get all the coil specs to match the whites, the timings will need to be altered. It wont be just as simple as changing a link on the board. Also to get the coil specs you need to measure the capacitance and inductance of the coil. DC resistance is only a small part of the equation. In a mono coil, its a combination of these factors that determines overall coil speed and its ability to see small gold. Too be honest you are better off trying a small commercial coil first before you start playing with your machine. If you make a coil and its not close to spec, you run the risk of blowing up the fets in the TX stage of the detector. [/QUOTE]
