My 6000's and XL Pro have been my main detectors for many years but the IDX Pro with Mr. Bills mods. and little Bullseye coil continue to impress me. I took the IDX Pro and Bullseye for a short hunt last night at an old one room school house that I have hunted many times over the years. It was a school between 1889-1930 and has been a community club since that time. Every new detector I've tested over the years has been over this small 1/2 acre lot. I thought this tiny coin was a Canadian Fishscale at first but its a 1920 British minted 10 cent coin from Ceylon (Sri Lanka). You can see the size of the coin next to the dime. It was about 6 1/2 to 7 inches down and gave a soft repeatable signal and read as zinc penny but would jump to dime from different angles. That is deep for such a small coin for my ground.
