I have an email from a prospector in Arizona about the problem of static build up on his detector. This is not a problem that I have encountered in the field as we do not have such hot dry conditions in the UK. I have seen it on industrial detectors where you get a static build up on a conveyor belt passing over a coil and, rarely, it can be so serious as to damage or destroy integrated circuits in the electronics. The detector in question is an SD2100 with a Coiltek 14in coil and the result of the static is to give a loud audio signal every time there is a discharge. The obvious area where static is generated is the plastic coil housing which rubs on the dry ground. The charge can then be transferred via the shielding and the cable to the case of the electronics. Discharges can take place anywhere
