Having all the same features as the basic verifier, this one also specializes in Bullion bars. The Precious Metal Verifier is used to measure the bulk metal in a bullion bar or coin and ensure that the metal matches the electrical characteristics that would be expected of it. The Verifier can assess a sample in less than one second and up to 2mm deep without affecting the coin or bullion in any way. The Bullion wand can penetrate up to 4mm deep. No chemicals are used and no physical damage is done to the coin or bullion being tested. Unlike in other testing methods, plating and surface features do not significantly impact the unit's ability to measure the underlying metal. Using electromagnetic waves that penetrate deeply into the coin or bar, plating and surface features are largely ignored, and the main body of metal assessed. The Verifier can see through plastic cases and bags, so numismatic coins do not need to be removed from protective holders. This verifier kit comes with the verifier, one small wand, basic wand, and the additional Bullion wand that specializes in bullion, a USB adaptor/charger, and a traveling case. Battery life should last 10 years.
