The new Frontier HD X models offer stunning high definition viewing with incredible colour control and phase correction. First class lens coatings on all surfaces throughout the binocular and dielectric coated prisms ensure the highest amount of light transmission.
All Frontier HD X binoculars pass through a strict quality control inspection to ensure all aspects match design intent. They are optically checked for resolution, light transmission and Strehl Ratio for optical image formation. They are further tested in extreme operational temperature conditions from -15°C to +55°C and storage temperatures -40°C to +70°C. Final checks of waterproofing to IPX7 and fog proofing are tested.
