Works and gives spot-on readings right out of the box.
I first used it with known composition silver and gold items to get a feel for the readings.
Then went to some of my "iffy" coins.
Not "iffy" in the sense of being fake, but I had several commemorative coins which I didn't know their composition.
Plus, the makeup of junk silver does vary (although not by much, but it's measurable with this unit) according to the coin and the year.
I was happy to learn that the commemorative coins were just above 96% which is about the composition of pre-2013 Britannia's.
The junk silver was all within range.
You might be surprised to learn there are several different settings for junk silver as follows:
90% US pre-1900
90% US pre-1945
90% Coin 1960
I bought the unit with the small and large wands and they work well.
I would have liked to have one with the bullion wand, but the additional price for what could not cost more than ten dollars to produce was just too steep.
I'm sure as production ramps up and initial costs are recouped, that the price will drop.
Not just for the PMV, but for additional wands as well.
I'll just wait.
In summary....it absolutely works as advertised and I'm very happy with it.
If you are a serious collector or stacker, this is a GREAT tool.
I'm a stacker, so I won't be buying a silver coin for $5000.00, but some folks do
AND, it is very true...catching just one fake gold coin/bar or high dollar silver coin and it will pay for itself.
