Got my Infinium back yesterday. Had sent it in to Garrett because the 8 mono was falsing so bad. I found it was the coil wire doing the noise when flexed near the control housing. When I set up the machine after receiving it (the box, 10x14 DD, 8 mono) yesterday it was a jaw dropper to start to hunt and have the same exact falsing with every swing. Again, I gently grasped the coil wire near the housing and gently flex the wire and.....bing bong bong.... This is a huge problem because I belt mount the box and when swung in each direction I get a false and at times in between swings. The more slack I leave in the coil wire the worse it gets. I have tried everything to get it quiet but the only thing that helps is to shaft mount the box so there is no flexing of the coil wire. My aging wrist and shoulder can't take the weight. I am going to call Garrett today to complain but I already know what the answer will be, " please, send it in and we'll check it out" - after all we only get to speak with customer service. This machine is going up for sale if Garrett does not bend over backwards to fix this problem.
