Hello everyone,
I am absolutely stunned at what I have just seen with my lowly Silver uMax. I got this detector about two years ago and have used it quite a bit, but I had never done any actual testing with it in my yard. Well, tonight I did, and I have to say the results were astounding. I decided to try a test on a regular clad quarter first. I dug a hole 7 inches deep measured and placed the quarter flat in the bottom of the hole and covered it up. I turned on my Silver uMax to all metal sensitivity 1 (Lowest). I could hear the quarter loud and clear. I turned on the disc and slowly turned it until it was all the way up and still sensitivity 1, and still I could pick up the quarter same intensity as in all metal. I couldn't believe it, but I got a big shovel and dug a hole 11 inches deep and repeated the test exactly the same as before (sensitivity 1), and got exactly the same result! Then I remembered that I forgot to check the area for other metals, so I removed the quarter and scanned the area. What I found was that there was three objects in the dirt directly over the quarter, a ferrous metal tab about 3/4 in. by 1.5 inches, a rusted washer, and a small piece of aluminum. The discrimination eliminated all of these objects and still picked up the quarter loud and clear on full discrimination at sensitivity level 1 at 11 inches with the stock 8 inch coil. I guess that explains why over the last two years, I have given up on many very good signals because I could not dig deep enough to get it. I was going to do more tests, but it began to rain and I had to go in.
