Hi all. I just had an idea for the quattro (and all minelabs for that matter). My dealer was showing me the new T-2 model a couple days ago. He showed me how the T-2 has a mineralization reading for the ground your working in at the time, and whether it's low or high mineralization. I think the quattro and all minelabs could benefit from having a mineralization reading like this on their machines. It would be a great help in helping one decide how to set and adjust their machines. But I'm no expert with detecting knowledge and so forth, and so this may be naive in conception. I was wondering what others thought of this idea? HH. Sincerely, Randy
