I've been hunting with a classic III for five years and just got my QXT Pro. Man I tell you it's great, I have found way more gold and silver than I've ever found before. Set your machine on the coin/ jewelry mode , search sen. on 16, VDO on , noise reduction off, this will get more static and false readings but you can tell them apart because they are not very repeatable and you can go even deeper. Listen for the very faint tones that repeat.You get the older stuff that way. I'm still learning also but that program seems to work very good for me. Also put Whites QXT programs in your search engine and you will get some other options. Always remember to pay very close att. to the size bars across the bottom when checking depth and pinpointing. A coin should only have 2 size bars, when this happens its a coin every time. screw caps reading is almost always a screwcap and foil is always foil. Dig every nickle/ring, most time it will be a pulltab but I've found some cool rings also. Anyway good luck and H.H.
