Hi, I recently bought the CTX 3030, I have been using Minelab Detectors for years now, but this CTX 3030 is far the best for me. I have found hundreds of hammered coins over the years, I have uploaded a mode to help those that want to find hammered in the UK, I hope this will help. The first pattern is for all hammered and other coins and the second pattern is for mainly silver and gold hammered. I would suggest you use the first pattern on a new undetected site, but on one that has been hit many times use the second. Always remember that the coil should be scuffing the ground at all times, too many just swing inches over the ground and miss the cream coins. sensitivity should be high but if chatter just reduce slightly till the chatter is gone.
