Product Information
Full details
The Olympus 10x21 RC II WP binocular is an ideal, durable companion for outdoor enthusiasts, travelers, and sports fans seeking a compact yet powerful viewing solution. Its primary benefit is robust, waterproof construction combined with 10x magnification for clear, close-up views in various conditions. A potential caveat is the 2.1 cm objective lens, which may limit performance in very low light compared to larger models. Key features include its waterproof and fogproof design, lightweight and foldable body, multi-coated lenses for enhanced brightness, and a wide field of view.

Are these binoculars truly waterproof?
Yes, they are built to be waterproof, meaning they can withstand immersion in water up to a certain depth and duration, and are resistant to fogging.
What is the closest focusing distance?
The closest focusing distance for the Olympus 10x21 RC II WP is 3 meters (approximately 9.8 feet).

Troubleshooting
Image is blurry or not sharp
Ensure the focus knob is properly adjusted. Clean the objective lenses and eyepieces. Adjust the dioptric correction ring on the eyepiece to match your vision.
Cannot see a single image (double vision)
Adjust the interpupillary distance by changing the angle between the two barrels until a single circular image is achieved.
Condensation inside lenses (fogging)
While designed to be fogproof, rapid temperature changes can sometimes cause temporary fogging. Allow the binoculars to acclimate to the ambient temperature slowly. If persistent, contact customer support.
Difficulty focusing in low light
The 21mm objective lens is best suited for daylight. For low light conditions, consider binoculars with larger objective lenses. Ensure lenses are clean for maximum light transmission.

- Durable and weather-resistant with waterproof and fogproof construction.
- Provides clear, magnified views with 10x magnification.
- Comfortable to hold and use with its rubber-coated exterior.
- Good image quality with multi-coated lenses for brightness and contrast.
Cons
- Smaller objective lens (21mm) may limit performance in extremely low light.
- 5.1° real field of view might be narrower for some fast-paced wildlife or sports viewing.

Setup, Compatibility & Care
Setup: The binoculars are designed for immediate use. Adjust the interpupillary distance by folding the binocular's barrels until you achieve a single, clear circular image. Fine-tune focus using the central focusing knob until the image is sharp. If needed, adjust the dioptric correction ring (usually on the right eyepiece) to compensate for any difference in your eyesight.
Compatibility: These binoculars are compatible with most users, including those who wear glasses, though individuals requiring significant eye relief might find them less comfortable. They are designed for general viewing purposes.
Care:
- Cleaning Lenses: Use a soft, lint-free lens cloth or a dedicated lens cleaning tissue. For stubborn dirt, slightly moisten the cloth with lens cleaning fluid. Wipe gently in a circular motion.
- Cleaning Body: Wipe the rubber-coated exterior with a soft, damp cloth. Avoid abrasive cleaners or solvents.
- Storage: Store the binoculars in a dry place, preferably in a protective case, when not in use to prevent dust accumulation and accidental damage.
- Water Exposure: While waterproof, it's advisable to dry the exterior thoroughly after exposure to water or heavy rain.
