Powerful Thru Readings
Make sure your pieces are 100% authentic using the Investor's thru readings. The onboard sensor checks all the way through samples, meaning there is nowhere for counterfeits to hide. You can rest easy knowing there are no inserts or bad metals in your coins.
Specific Gravity Testing
Put the calipers away. Using known metal densities and an automatic thickness measurement, the Investor takes the entered weight and calculates the expected size of your sample. Simply compare your coin or bar to the calculated size to ensure it's the right density.
Convenience and Power
The Sigma Metalytics Investor can easily travel with you to shows, auctions, estate sales, shops, and wherever else you might need to authenticate your purchases without sacrificing any power.
Three Wands
The Investor also comes with three wand attachments that enable it to perform surface measurements on a broad spectrum of sample sizes, ranging from 1/10 oz of gold to 10 oz of silver.
