The NEW Clarion dual base magnification thermal scope is one of the most technologically advanced thermal scopes in the world. The new Clarion scopes were meticulously designed to solve one of the biggest problems many night hunters face, which is selecting which lens size/sensor configuration will provide the optical base magnification and field of view for each hunter's primary application. The Clarion alleviates this concern by incorporating a dual-lens optical system that has the ability to mechanically alternate between a 25mm lens or a 50mm lens. This feature alters the base magnification and field of view with no degradation of the image resolution! With the Clarion 384, Mfg: Agm Global Vision
