Our values lead the way.
Rigorous Quality Assurance
Every pair of binoculars goes through strict multi-stage testing before shipment. We verify optical alignment, light transmission, prism seating, focus-wheel smoothness, water-seal integrity and housing durability — so you get a clear, dependable view on every outdoor trip.
Innovation, inherently accessible.
Our binoculars are made for everyone who loves the outdoors, with thoughtful built-in features — a wide 22mm eyepiece, FMC multi-coated optics, BAK4 prism and smartphone-adapter ready design — so you can follow your passion in your own way.
Customization & Flexible OEM/ODM
We support full OEM/ODM customization, including logo printing on the housing, color matching, accessory options (smartphone adapter, tripod, carry bag), hang tags and packaging — to match your brand identity.
Durable, Considered Materials
Carefully selected optical glass and a lightweight aluminum-magnesium alloy housing, built for long-lasting use with reusable packaging.
Questions? Answers.
Are these 20x50 binoculars really 20 times magnification?
Yes. The Frontlong 20x50 binoculars deliver true 20x magnification with a 50mm objective lens, so distant objects appear 20× closer than to the naked eye. Because of the high power, we recommend steady hands or a small tripod for the sharpest view.
Are these binoculars night vision? Can they see in the dark?
They are low-light (not infrared digital night vision). The large 50mm objective lens and FMC multi-coated BAK4 prism gather more light, giving brighter, clearer views at dawn, dusk and under tree cover. They will not see in total darkness.
Are these binoculars waterproof?
They are everyday splash- and rain-resistant (surface sealed), handling light rain, dew and splashes. They are not designed for submersion. Store them dry and wipe off moisture after use.
Can I use these binoculars while wearing glasses?
Yes. With 20mm eye relief and a wide 22mm eyepiece, you can keep your glasses on and still see the full field of view. Twist-up eyecups adjust to your eye distance.
Can I attach my phone to take photos?
Yes. These binoculars are smartphone-adapter compatible. A universal phone clamp (not included by default) lets you record what you see and share it easily.
How heavy are they? Are they portable for hiking?
The bare unit weighs 875g (about 1.9 lb) with an aluminum-magnesium alloy housing — light enough for all-day carry, yet rugged. It comes with a carry bag and neck strap.
What can I use these binoculars for?
They suit bird watching, hunting, hiking, wildlife, concerts, sports, safari and stargazing. The high power and large objective make them especially strong for long-distance, low-light outdoor viewing.
What comes in the box?
Each set includes the binoculars, gift box, carry bag, lens caps, neck strap, cleaning cloth and user manual.
