We can dream can't we?? After reading awhile on the forums about tech available now days, I would like to see a new pi nugget detector built by a company that will sell at a reasonable price, with a timing switch, 8 usec timing for tiny gold nugget hunting to say half grain sensitivity, and a 10 usec timing for standard nugget hunting. Auto ground bal with switch on handle access for quick tuning, track/lock on panel, auto freq set, tone control, volume control, sensitivitiy control, threshold, iron id. The 8 usec timing position would require a special wound small coil for tiny nugget hunting, the 10 usec timing could accept any size current dd or mono minelab coils. And I would like to see this machine with a full power sizable battery pack, something that would last an entire day detecting. I am getting tired of listening to VLF noise when out hunting tiny nuggets, a pi with 8 usec capability would be a pleasure to run I am sure. I guess what I am saying is I want a pi detector that will replace my GB2 and GPX at the same time!!! Perhaps add a third smooth type timing for super hot ground. Or one could just switch to dd coils for hot ground. Make it simple yet complete.
