The Fisch checks for common metals of a lesser density of gold, the Ringer checks for tungsten that has a density
very similar to gold. Someone buying Fisch without the Ringer is only going half the way for the reason
Tungsten is a real threat and will not be detected by the Fisch, hence the need for the Ringer.
