I've been experimenting some more with the mxt pro, and I've come to notice that it will overload on targets such as a bottle cap that are on the surface. I have turn the gain down to around 5 to get it to stop overloading on the bottle cap as I skim over the top of it or as I center it inside the 950 loop. I am in doors testing, so maybe that has something to do with it to. Funny thing is, quarters don't seem to bother even at the preset? I read a couple of others had this problem with pull tabs. Any one else have the same results? Is this normal for the mxt pro? I don't want to send it in already if there's no need, but I guess it's better now than after warranty runs out if it has something wrong it. Please share some insight.
