Folks, i got my machine back. Fisher was very kind in replacing a bunch of parts on it probably practically rebuilding it. It has the ma ma in disc though, in which i usually hunt. I have a friend who uses a different brand machine and i hear him ma maing all the time when pinpointing. I mean is the ma ma electronically another way and or voice for operating a pinpoint feature? Or is it there as a problem? It helps to raise the coil, but in a quick normal pinpoint swing it sounds across a very long arc. Too powerful in a sense. Ive heard some the 75ltd units brand new however dont ma ma. Mine was a very old camo. I may consider talking to them about it. I will get outside (2 feet of snow here) in a parking lot with some coins to test it. If they can hone that back more towards the way it was pinpointing before the upgrade Id be happier. Any input? CO
