The GT with a Sun-Ray S-5 coil cleaned out all the clad I missed with the other detector with the big coil. I wish I could report silver or better but I cant today. Lots of uneven terrain, deep tire ruts, erosion, etc. The GT went right in and cleaned house. For now.... Next week it will start all over again with new dirt piles, asphalt, concrete, clumps of sod and grass, and bulldozers. I'll be in the mud. HH. Matt
