Just got back from using my updated QII with the QXT PRO software. After all the talk bout it being a little unstable and the like I was a little leary. Even the service center was iffy on this. Anyway took it to the worst park for trash I know in these here parts turned her on and let her go. I adj'd the tracking and noise filter used the coin program and bingo . A nickel id'd perfectly at 6" and sure enough there it was bout the 6" mark . One time lucky! nope! 15 coins latter all with good ID along with 5 pull tabs and 1 bottle cap again with good ID . Well I had to proud to myself that the ID for the bad was as good as the ID for the coins. It sure is fun !! thx's for listening.
