Perfect for air cooled Volkswagens where you need extra depth to get past cylinder tins.

out of the box... scarily inaccurate.
The first CVD lab grown diamond tested with this unit tested natural over and over again. I ended up buying the GIA iD100 at 10 times the price to make sure that we were covered. I'm glad I hadn't relied solely on the SmartPro for purchasing as it might have led to an expensive mistake.
I am going to keep this unit and test it further to see if I can zero in on why it gives bad results. Maybe the CVD lab grown diamond was too big, or maybe it's less accurate on mounted diamonds, however I definitely will not be relying on it for day to day purchasing.
