Twist-Up Eyepieces: The contoured twist-up eye pieces with stop positions allow you to set your correct eye relief depending on personal preference or if eye glasses are being used.
Ergonomic Design: When using binoculars for extended periods, flaws in design can quickly become apparent. Designed with this in mind, all Frontier binoculars use a sculpted rubber outer with all controls within proportion of each other. The rubber itself has grip sections, larger on the heavier 43mm objective models and finer on the light weight 42mm and 32mm models. The smooth focus knob, with a 1.7 full turn mechanism, fits neatly within easy reach and operates well even with gloved hands. Eyecups are contoured and the dioptre is easy to set-up.
Extra Low Dispersion Glass: Reducing chromatic aberration with ED glass, the Frontier binoculars allow every detail to be seen with crisp, clear colour reproduction. Phase corrected prisms and fully multi-coated optics increase brightness even in poor light conditions.
