Normal use in the field but works fine if not better than a new one, it is fully guaranteed to work when you receive it. This unit is about 4 years old I used it to find artillery shells beyond the reach of ordinary metal detectors, the range an depth of the shells ran from 3 feet to 5 feet depending on the size of the shell. I put camo tape on the unit to hide the bright yellow were the unit would not stick out like a sore thumb in the wood's. The only reason I am selling the unit is to pay for this new Whites TDI I bought. I will take 300.00 for the Magnetometer shipped to your door. Postal Money Orders only. Lamar Cannon
