Ferolix JR04-0842 is a premium 8×42 roof prism binocular built for outdoor observation, bird watching, hunting, wildlife viewing and sightseeing. Designed for both end users and bulk optical dealers, this binocular combines BaK4 prism technology, MC multi-layer coating and IP7 short-term immersion waterproof protection.

All lenses and prisms adopt high-quality optical glass. MC multi-coating reduces light reflection and achieves 69% transmittance, enhancing brightness and contrast in twilight and low-light environments.

21mm long eye relief paired with twist-up eyecups offers comfortable viewing for eyeglass wearers. Diopter adjustment range from -5 to +5 diopters corrects eye difference between left and right eyes. Interpupillary distance adjustable from 58.7 mm to 74 mm fits most face shapes. Central focus mechanism enables fast, precise focusing.

The body is constructed from semi-aromatic thermoplastic PPS material with PVC cover, durable and lightweight at only 692g. IP7 waterproof rating supports short-time immersion for rainy outdoor use. Three optional colors: black, green, coffee.
