Elaborately multi-coated lenses provide an excellent viewing experience with pin sharp and crystal clear images. All lenses and prisms are made of special Nikon Eco glass, which is manufactured without arsenic and lead. The carbon fibre reinforced fibreglass construction is extremely durable, waterproof and fog-free. The rubber armouring increases the impact resistance and supports the pleasant grip. The rubber eyecups can be adjusted to fit the eye in several positions. Due to the large distance between the eyes even spectacle wearers enjoy a wide and clear sea field.
