On my last dig in the UK I had a lot of problems with my CTX. There was a lot of (big) iron in a stubble field. I received a lot of signals between ID range 12/34 - 12/41. Everytime it appeared to be iron. I used gordons tadpole settings, with auto +3 (but also changed it to auto and manual 20). Deep on, fast recovery off. I started with ferrous-coin (also tried ground-coin) and sounds smooth. After 2 hours with only digging iron and nothing else I tried my other detector the XP Deus. Within 30 minutes I found 4 coins and 5 buttons and some pieces of lead. Any advise would be welcome!
