Well, the "Dig ALL" idea, or using All-Metal would literally put you in a 20'X20' box for the next year or so! and this park is a little over 110 acres. What we're doing now is still trying to stay about the millions of tabs, thousands of aluminum screw caps, and other litter. Whenever we go out we are getting a good bit of these items but its not possible to CLEAR a 110 acres of a city park that's been a park sense 1920! it just has to much trash.
So, the idea now is that all the cherry picking is pretty much over with, all the 'Let The Meter Tell Me To Dig It Or Not' is history.
We're trying to drop are discrimination down to maybe the Zinc range, or screw caps and dig the repeatable signals. My thinking is that a good bit of what's left is tucked up tight to other junk items that are good conductors and so the coins are being averaged up or down enough to throw them out of their ID range of. So, how can you find a silver quarter with a detector that has Visual ID if the quarter is now being averaged down to a screw cap, or a zinc penny? It would seem to me that we are just going to have to set the discrimination to some point below the high conductive coin range and just cover the meter up and pick out the responses via an audio report. Now, if that's so then there is some reasoning to the reverting back to what some may call "Old School".
My brother and I have been tossing the idea around of him taking his 1270 and me firing up my 1266 and going back over some of the areas that are still radioactive from our,

You' ve answered your own question! But many of the newer detectors, like my MX 5 ID in a/m motion! You can sometimes, also pick up several objects close together. I understand the Makro Racer is making the news by picking out objects deep amongst trash and in the iron.

and going for the decent responses from zinc's up.
This should put us at digging more trash, but if the good stuff starts to turn up more then that would be a better day than a whole day with nothing good.
