The LEADER binoculars are designed for demanding users. The lens finish secures high sharpness and luminosity of the optics. Integration of dioptrical setting into the central focusing simplifies the individual setting of the observer in question. The scope lids are fitted with practical clamps preventing their loss. The scope is filled with dry nitrogen, which secures that it is waterproof and dustproof. It also completely eliminates internal dewing of the scope upon a change of ambient temperature. The body of the binoculars is made of polycarbonate, which secures its strength. It is further protected against damage by a completely rubberised coating. The scope focuses from 3 m.
