Model: Bushnell R5 10×42 (“R5-1042”) Ranger Green, Roof prisms.

Magnification: 10×.

Objective lens diameter: 42 mm.

Prism type & glass: Roof prism, BaK-4 prisms.

Optics coatings:
• Fully multi-coated lenses (anti-reflection coatings) 
• Dielectric prism coatings for higher reflectivity. 
• Phase-3 phase correction coatings on the prisms.
• EXO Barrier coating on the exterior glass surfaces (to repel water, oil, dust, etc.)

Waterproof / fogproof construction: IPX7 rating, nitrogen filled so fog won’t form inside.

Colour: Ranger Green — this helps with camouflage/less sheen outdoors.

Extras: includes chest harness (Vault Lite), neck strap, etc.

Brightness and contrast: The combination of a 42 mm objective and the various coatings (dielectric, fully multi-coated, phase-corrected prisms) means fairly good performance especially in twilight / dawn / dusk.

Weather durability: EXO Barrier + IPX7 + nitrogen fill means they’re built for harsh outdoor conditions — rain, dew, rapid temp changes. Good for safari, birding in damp mornings, etc.

Solid optics: BaK4 prisms and dielectric coatings help reduce losses/reflection and improve clarity, colour fidelity. Edge performance tends to be better in such setups.

Practical magnification: 10× gives a good zoom factor for wildlife/distance work without being too high (which could make handheld use shakier).

Ranger green build: Less conspicuous in natural settings; good for stalking, hunting, wildlife viewing.

Wildlife viewing / birding in South Africa, especially in mixed lighting (forest edges, bush, dawn/dusk).

Outdoor activities where durability and weather resistance are important.

Users who want a good balance between performance and portability — not the cheapest, but not ultra-premium either.
