I had been using the concentric 5x8 coil for about two years now. I liked the DD but had never used one before so I purchased the 5x8. Well after deciding that I had learned some of the ins and outs of the detector I thought I would try the DD again. I put in on today and went out in my backyard that I have hit many many times. Found several things at much deeper depths than the 5x8. 1959 Lincoln, 1962 and 1966 make me feel like I have gotten to the depths of older coins that I need to be at. I even found a RING!!! It was plastic though and was with two of the pennies I found. Just thought I would mention the difference in depth I have noticed already with the two coils.
