Abstract
Un detector de metales o catador, que comprende un carrete de ensayo conectado a un generador de corriente alterna de alta frecuencia, caracterizado porque el carrete de ensayo constituye una parte de circuito sintonizado de un oscilador cuya relación de retroactivación depende del factor Q (factor de amplificación) de dicho circuito sintonizado y porque se dispone un instrumento de medición par indicar la tensión alterna en el oscilador.
