[QUOTE="WalnLiz, post: 3687, member: 147"] Hi Keen Ken...we use to build detectors back in the days of the old Garret Ground Hogs....and wound several coils inside old frizbies ...my neighbor was a scientist with the defense force and had access to some really good oscilloscopes.... so the transmit and receive windings could be tuned fairly precisely. The technology was a bit more primitive in those days and i don't think I'd go to the trouble today. :) Good fun though if you want to give it a go. Cheers Wal. :) [/QUOTE]
