I have a Pioneer 505 which I think is a quite good machine with all of the functions that seem necessary and few frills I don't mostly depend on. I've been invited to Cali to a gold hunt. This will be nuggets, small of course, because as it's explained to me - MD's don't pick up gold dust unless there's a tee total ton of it. My question is - does the Pioneer 505 have a chance with such a target? Does anyone have any experience with it? The Pioneer 505 is about like a Sharpshooter II. Thanks and happy holidays to everybody!!
