The Pocket Pinger + Stack Stick, Coin Ping Test (Black, 1 Pack) + StackerTools App

Excellent little tool, definitely works and worth the money, thanks.

I had been trying to find a way to get one of these, in Canada. The manufacturer ships them free to any US address but then wants US$ 20 to ship this item to Canada. When I found it on Amazon.ca and it qualified for free shipping, I placed the order. This is well built and functions just like advertised. Amazon was the cheapest way to get this device into my hands although I see I must have bought the only one they had as this is now marked as out of stock with no refill date. I guess I got lucky!

Very good tool for precious metals

This device along with the great free app you have access too, is the surest way to me to tell if your silver is real or fake. I tested about 300oz of junk silver using this and had no issues. Worked great, and feel very good about my stack being legit. A negative i did have is using and testing Mercury and Roosevelt 90% Dimes. Although i was able to mostly tell if my coins i had were real or not. It took several pings to register and some coins failing for no reason (not fake-confirmed) It looks like this is still in a beta stage on the app, but i hope they urgently fix this and get it working for Dimes 100%.

works nice!
