I use a texas pro, got at a yard sale, 30.00 I put it on the iron an metals setting, has been good at finding nail, fence staples, and always check ur wood for metal staining, and where it came from, the setting I use on the detector, avg's 10 to 12 inchs in so I just roll the log over, I learned the hard way, paid for it, by having to buy some new bands for my mill.. good luck
