You are going to love the F-75. Try not to run the sensitivity too high. 50-60 works the best. 80-90 for nugget hunting. Ground balancing is very important. It has a trigger that you move forward while pumping until hum fades. Do this every 10-20 minutes for optimum performance. I have made several deep silver dime finds while hunting with friends, who have Whites, Garrett's, and Tesoros,. We listen to each others hits and try to guess what it is, and almost without fail, the F-75 locates and predicts the deepest finds! One buddy, who uses the White MXT, has told me he would never have even dug some of the hits on the F-75. They all turned out to be silver coins. And he is one of the top detectorists in the Chicago area with over 6000 silver coins. Including a 1916-D merc. , 2- 1896-S barber Quarters, 1921 merc, 1877 Indian penny, and numerous other key dates. He used a Fisher CZ-6 for 20 years, then bought the MXT about 4 years ago. He has had two major articles written about his finds in the Chicago Tribune. We detect 15-20 hrs. per week for 25 years. Let me know how you like the F-75. Or if I can help with any questions?
