Used. Tested and working. Unit powers on and detects metal. One of the AA battery holder cases is starting to crack at one end, but the batteries still sit in place and the unit still works. The clear plastic cover over the 0 to 100 meter has a small crack. Includes headphones. Headphones do work, but they are spotty and the left/right volume can be scratchy when adjusting the headphone volume knobs. Shows normal cosmetic wear from age and use.
