Testing the Kite Optics APC Stabilized 18x50 ED Li-ion Binoculars:
A Revolution in Observation
The Kite Optics APC Stabilized 18x50 ED Li-ion binoculars from Belgian brand Kite Optics are designed for nature observation enthusiasts, whether birdwatchers, hunters or hikers. Tested over a weekend at the Domaine L'Ermitage in Sologne, these stabilized binoculars impressed us with their clarity and ease of use. If you're looking for binoculars for long-distance birdwatching or game observation, this model could well become your best companion!
Unpacking and first impressions
When you open the Kite Optics APC Stabilized 18x50 ED Li-ion Binoculars box, you'll discover a complete and well-thought-out set of contents: the binoculars, a rechargeable Li-ion battery, a USB-C cable, a comfortable neck strap, protective lens caps and a sturdy carrying case. The elegant, modern design is immediately appealing. At 750 g, they are slightly heavier than conventional models, but this reflects their solid construction. The rubber coating provides a pleasant, non-slip grip, perfect for prolonged use in hiking or static observation.
Optical quality
The optical quality of the Kite Optics APC Stabilized 18x50 ED Li-ion Binoculars is simply outstanding. Thanks to their 18x magnification and ED (extra-low dispersion) lenses coated with MHR Advance+, they offer impressive clarity and vividness, even in low-light conditions.
Light transmission reaches 86%, making them ideal for twilight or dawn viewing. During a birdwatching outing, we were able to spot a deer at over 400 meters with remarkable clarity, every detail of its antlers perfectly visible. The apparent 61° field of view is also an asset when tracking moving wild boar or surveying a large area.
Ease of use
Kite Optics APC Stabilized 18x50 ED Li-ion binoculars are outstandingly ergonomic. KT3.0 stabilization technology, combined with the KDGS-2 system, effectively compensates for shaking, making 18x observation incredibly stable, even without a tripod.
Whether for a long hike or a static observation session, comfort is guaranteed. Adjustable eyepieces are ideal for spectacle wearers, and the focus wheel is smooth and precise. During a day's birdwatching in the forest, we appreciated the relative lightness and stability, enabling us to track fast-moving passerines effortlessly.
Sturdiness and practicality
Designed for outdoor adventures, the Kite Optics APC Stabilized 18x50 ED Li-ion Binoculars are a model of robustness. With an IPX7 waterproof rating, they withstand immersion down to 1 meter, and their nitrogen filling protects them from fogging up, even in heavy rain. Tested during a hike under capricious skies, they lived up to all their promises. Their 38-hour autonomy, thanks to the Li-ion battery rechargeable via USB-C, is a real plus for long outings. The supplied carrying case and strap make them easy to carry, whether around the neck or in a backpack.

Comparison with other models
Compared with the Kite Optics APC Stabilized 14x50 ED Li-ion Binoculars, also available on binoculars.com, the 18x50s offer more powerful magnification, ideal for very long-distance observations, such as hunting or surveillance. The 14x50s, on the other hand, are a little more versatile for activities such as birdwatching on the move, thanks to their slightly more moderate magnification that makes it easier to follow fast-moving subjects. Both models share the same outstanding optical quality and stabilization technology, but the 18x50s stand out for users looking to see further with greater precision.

Kite Optics APC Stabilized 18x50 ED Li-ion Binoculars User Manual
Using the Kite Optics APC Stabilized 18x50 ED Li-ion Binoculars is child's play, even for beginners. Here are the steps to get the most out of them:
1. Initial preparation: Before your first use, charge the Li-ion battery using the USB-C cable supplied. A full charge takes around 3 hours and provides up to 38 hours of autonomy. Make sure the protective caps are removed from the lenses.
2. Adjusting the eyepieces: Adjust the distance between the two eyepieces by moving them further apart or closer together to match the distance between your eyes - you should see a single, circular image. If you wear glasses, raise the eyecups; otherwise, leave them down for optimum comfort.
3. Focus: Locate your subject with the naked eye (for example, a bird perched 50 meters away). Bring the binoculars up to your eyes and use the central focusing wheel to adjust sharpness. If your eyes have a difference in vision, adjust the diopter correction (on the right eyepiece) to balance the image.
4. Using stabilization: APC technology is activated by clicking the stabilization button as soon as you hold the binoculars in the observation position. If you let them hang around your neck, they go into standby mode to save battery power - a real plus for long days of observation! On a hunting trip, for example, you can observe a deer at a distance of 300 meters without the tremors interfering with your vision.
5. Care after use: After a day in the woods or in the rain, clean the lenses with a microfiber cloth to avoid scratches. If they get wet, rinse them in fresh water (they are IPX7 waterproof) and leave them to dry before storing them in their case.
Whether you're watching birds at sunrise or keeping an eye on a deer in the forest, these binoculars will give you a stable, immersive visual experience. Enjoy every detail, even at long range!
