10-30X 50mm Waterproof Monocular

With 10–30× zoom capability and a 50mm objective lens, this monocular delivers versatile, high-resolution viewing for varied outdoor and indoor applications. Its optical path integrates FMC green-coated lenses and BAK4 prisms to ensure excellent light throughput (up to 99.5%) and minimal chromatic aberration. Designed for usability in challenging conditions, it features O-ring sealed optics that make it fully waterproof and fog-proof — impervious to rain, mist or temperature shifts. The body is constructed with durable plastic-steel glue armour and features an ergonomic, anti-slip textured grip for stability during movement or vibration. A universal smartphone holder is included, enabling seamless attachment and image/video capture across mainstream phone models. Its lightweight yet robust form factor supports extended handheld use — whether tracking wildlife, observing stadium action or exploring cityscapes.
