A big thumbs up to everybody here on the forum who have posted on the solutions to problems that inexperienced users of the MXT have encountered....It surely shortens the learning cure & points one in the right direction to learning how to get the most out of this nice little beeper...I've only had mine for a couple of weeks & took it out for a test drive without really knowing how to use it...At first I tried my own "dialing in" & then tried the factory presets....Let me tell each & every one of you that you have really help immensly at shortening the learning & frustration curve...I haven't tried as of yet any "serious" detecting with this unit "MXT"....but will shortly because of every person who has taken the time to say....turn down the threshold & boost gain or vice versa...I probably don't even have a total of three hours time on this detector yet but by going out & detecting for a half hour here & an hour there & then comeing back to the forum & reading similar posts of problems encountered it shouldn't be long before I start posting pics...Thank you ALL VERY MUCH...Tom
