Hey Dick;
You might try using a MD earlier in the year, then switching to panning when the water levels drop? Previously, I never owned a good MD with manual ground balancing that could detect gold through the highly mineralized soil here, so I stuck with panning. It's only been over this past winter, when I found this website that I decided to see if there wasn't some way to increase my gold finds by getting a better MD. I still plan on panning, for the enjoyment of it, but with the increases in fuel and living costs, I hope the MD will increase my earnings.
The MD I just had given to me was involved in a fire, but I hope to fix its audio problem and have it fully functional soon. I'm opening her up tomorrow to see if I can spot the problem. Its just an old Compass Magnum 420 MD, but its the first MD I've owned that has ground balancing and from what I've read, it was known as a good nugget machine in its day.
Anyway, since you already have experience with swinging a MD and are familiar with areas that might be thin on nuggets while being rich on flake, or flour gold, you might find as I have, that panning can be more consistent in it returns, (depending on the particular area your in), simply because of a lack of coarse gold. I don't have the fanciest equipment and most if what I do have is improvised and patched together, but I'm slowly working on improving both my tool selection and my knowledge of prospecting techniques in general. I've posted links to some of the information I've come up with in this forum and in particular in the following thread:

I'm not out for the big score, but I do expect to increase my returns by working smarter and taking advantage of opportunities that others often overlook. If you want in to increase your take from panning, there are a few webpages around that go into detail on what to do with tellurides, like this one:

Good luck and have a great summer!
