The Nautica
models - whether you want center focus, traditional individual focus, or a model with a compass and reticle. All are
rubber covered to protect against rough handling. All provide maximum optical performance with BAK-4 prisms and
multi-coatings for sharp images with high contrast and resolution. Each model has a large, 50mm objective lens to
offer maximum image brightness even in low light conditions, like dusk and dawn.
