Heck we have a lot of good top of the line units by different manufactures and all have the plus and minus features but having used them all would be hard to find a unit as good as an Explorer for silver coins. The trick is to learn your units to get the best out of it and am sure we could have debates and many could make good points in favor of their favorite unit so grab your favorite and go get them as units are only as good as the ability of their user...
