All Frontier 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.
Frontier HD X are available in a choice of green or grey body, with either 8× or 10× magnification and with option of full size 42mm objective lenses, or more compact 32mm objective lenses.
