Yes, a NOOB here with a quick question. Using my brand new MXT Pro yesterday in Relic Mode, discrimination and gain set to the triangles, I got a VDI rating of +74 on a target (buckle appearing on the display). A couple of inches down I uncovered a piece of iron measuring roughly 2x4 and about 3/8 thick. Placing the coil near the object would put the MXT into overload, even after turning the gain setting way down (2-3).
That last observation isn't my greatest concern and may even be normal, but I'm wondering why I'd get a positive VDI reading at all, not to mention a high one on a chunk of iron. Heavy, rusty, sporting cobby welds and sticking to a magnet were characteristics that make me think of ferrous material.
Again to emphasize, this MXT is new to me and you might as well say I'm brand new to the activity. Rightfully so I'm looking at the user and not the machine as the issue for any hiccups or anomolies for awhile, but would like to rule out there's something funky in the machine.
Any input will be greatly appreciated. TIA!
