The Large Gold Lock Coin Tester (Patent #9,934,639) is a low-cost portable tungsten illuminator that is small enough to fit in a pocket and does not require batteries. This test apparatus is designed to detect tungsten inside gold and silver objects. Tungsten (19.25 grams/cc) is nearly the same density/weight of gold (19.3 grams/cc) and is the ideal material for counterfeiting gold and silver objects due to its relatively low cost ($4/ounce) and nearly identical density/weight.
Does not work on clad coins, bullion or bars. Recommended for investors that deal with significant quantities of unclad coins.

How to use
Place the coin inside the Tester. Move the magnetic activator in small circles close to the Tester. Magnetic anomalies will be illuminated by a visible distortion in the green aurora of the Tester lens; this indicates a foreign body in the gold or silver.
