Endurance ED spotting scopes provide the performance to get close to the action and the durability you demand.
All magnifications are constructed with ED glass reducing the potential for chromatic aberration. ED glass controls colour fringing and allows an improvement in clarity and crispness of the image, highly recommended by nature enthusiasts.
All lenses are Fully Multi-Coated and prisms Dielectric Coated for increased reflectivity. Endurance scopes feature a dual focus knob (coarse and fine), 3x ratio eyepieces with twist-up eye cups and retractable sunshades.
