Binoculars kite optics APC stabilized 18x50 ed li-ion:
A revolutionary observation experience
Discover the Kite Optics APC Stabilized 18x50 ED Li-ion binoculars, a true technological gem for enthusiasts of birdwatching, hiking, or astronomical observation.
Designed by the Belgian brand Kite Optics, renowned for its expertise since 1992, these stabilized binoculars combine high-precision optics with advanced image stabilization technology. Whether you are a birder seeking to observe birds in flight or a fan of distant landscapes, this model will provide you with an unrivaled visual experience thanks to its ED optical system and innovative design. Available in two formats—rechargeable Li-ion battery or AA batteries—they adapt to all needs.
An ergonomic and innovative design
The Kite Optics APC 18x50 ED Li-ion binoculars stand out immediately for their unique design, both modern and functional. Their appearance, reminiscent of classic binoculars, is enhanced by a contemporary touch with a robust housing and refined finish. The 4 cm long focusing wheel is designed to be easily operated with three fingers, offering optimal ergonomics during extended observation. This intuitive design makes it a perfect choice for users of all levels, whether beginners or experts.

KT3.0 image stabilization technology: exceptional stability
The heart of the Kite Optics APC Stabilized binoculars lies in their KT3.0 image stabilization technology, an innovation by Kite Optics. This technology, coupled with the KDGS-2 module (Kite Dynamic Gimbal System), provides a 2° correction angle, delivering stability two to three times greater than that of standard stabilized binoculars. Whether you are on the move, aboard a boat, or simply hiking on a windy day, these binoculars eliminate shake for a perfectly steady image, ideal for nature observation.
ED/HD optics for unrivaled clarity
The 18x50 ED Li-ion binoculars incorporate an ED/HD (Extra-low Dispersion) optical system that minimizes chromatic aberration, ensuring sharp and true-to-life images. With 18x magnification and a 50 mm objective diameter, they deliver exceptional clarity, even in low-light conditions. Whether you are observing a raptor at 1000 meters or the stars during astronomical observation, every detail is rendered with remarkable precision.
Optimized light transmission with MHR advance+ coating
Thanks to the MHR Advance+ coating from Kite Optics, the lenses of the APC 18x50 binoculars achieve an impressive light transmission of 86%. This feature, combined with the “Enhanced Brightness Perception by Stability” technology, enables optimal observation in dark environments or at dusk. Colors are vivid, contrasts are striking, and clarity is maintained even during low-light observation.

A wide-angle field of view for total immersion
With an apparent field of view of 61° and a field of view at 1000 meters of 65 meters, the Kite Optics APC Stabilized 18x50 binoculars provide a panoramic viewing experience. This wide-angle field, compliant with ISO standards for wide-field binoculars, makes it easier to spot birds or moving animals, making these binoculars ideal for birdwatching and wildlife observation.
Exceptional battery life: up to 60 hours of use
The Kite Optics APC 18x50 ED Li-ion binoculars are equipped with a rechargeable Li-ion battery via USB-C, offering 30 hours of use per charge. A second compartment allows you to store a spare battery, extending the total battery life to 60 hours. This outstanding endurance is perfect for extended nature observation sessions or wilderness expeditions.
APC mode: intelligent power management
The APC (Automatic Power Control) mode is an ingenious feature that extends battery life. Integrated sensors detect the position of the binoculars: when they are vertical, hanging around your neck, they automatically switch to standby mode. As soon as you pick them up, stabilization is instantly reactivated, without pressing a button. This function is ideal for uninterrupted observation.

Low battery indicator for peace of mind
A low battery indicator, located on the front of the Kite Optics APC binoculars, warns you several days in advance when the battery needs to be recharged. Additionally, a timer function completely powers down the device after 90 minutes of inactivity, preventing accidental discharge. This attention to detail ensures stress-free use during your outings.
Rugged durability: Engineered for extreme conditions
The Kite Optics APC 18x50 ED Li-ion binoculars are built to last. With IPX7-certified waterproofing, they withstand immersion up to 1 meter for 30 minutes. Their nitrogen-filled body protects them against fogging, and the sealed electronics ensure optimal performance in humid environments, such as during coastal observation or in the rain.
An ideal companion for all your adventures
Whether you are heading out for a mountain hike, a boating trip, or an astronomical observation session, the Kite Optics APC Stabilized binoculars are ready to accompany you. Their robust construction and compact design (152 mm wide) make them a practical and easy-to-carry tool, even over long distances.
Ergonomics designed for comfort
The ergonomics of the 18x50 ED Li-ion binoculars is a major asset. Their 1 kg weight is well distributed, and the adjustable interpupillary distance (from 57 to 76 mm) adapts to all users. The 15.5 mm eye relief is ideal for eyeglass wearers, ensuring optimal visual comfort during extended observation.
Versatility for all types of observation
With a 18x magnification and a 50 mm objective diameter, these binoculars offer impressive versatility. They excel in both birdwatching and landscape observation, as well as amateur astronomy. The minimum focusing distance of 5.5 meters allows you to observe nearby subjects, such as insects or flowers, with remarkable precision.
Exceptional contrast and color fidelity
The optical system of the Kite Optics APC binoculars guarantees unmatched contrast and faithful color reproduction. ED lenses reduce color fringing, and MHR Advance+ coatings optimize light transmission, delivering a bright and natural image, even during twilight observation.
Tripod compatibility for increased stability
For extended observation sessions or to maximize stability at high magnification, the Kite Optics APC 18x50 binoculars are tripod compatible. An adapter (not included) allows for easy mounting, which is particularly useful for astronomical observation or viewing stationary wildlife.
An AA battery alternative for greater flexibility (But prefer Li-ion batteries)
In addition to the Li-ion model, the Kite Optics APC 18x50 ED binoculars are also available in an AA battery version (APC 18x50 ED AA model). This option is ideal for users who prefer a power source that can be easily replaced in the field, offering up to 38 hours of operation per set of batteries. This flexible choice meets all needs, whether you are on an expedition or a day outing.
30-year warranty: A mark of quality
Kite Optics is renowned for its exceptional after-sales service, and the APC 18x50 ED Li-ion binoculars are no exception. They come with a 30-year warranty, a true mark of confidence in the durability and quality of this product. In case of any issue, the Kite Optics workshops in Belgium provide fast maintenance or repair.
