The old TR machines back in the 70's would see coins directly beneath iron, with the Compass 77b being legendary in that respect, something a VLF will never do, no matter what coil or how much the machine cost. I used to hunt behind VLF's at old house sites with a TR, lots of nails, and lots of coins the VLF's missed, and whose owners declared the site "hunted out".
