KITE Optics APC Stabilized 18x50 ED Li-Ion binoculars are designed for users who demand maximum magnification, unmatched image stability, and premium optical performance in a lightweight, field-ready package. With 18x magnification and 50mm extra-low dispersion (ED) objective lenses, these binoculars deliver razor-sharp, high-contrast images with minimal chromatic aberration—ideal for long-distance viewing, wildlife observation, surveillance, and marine use.
Equipped with KITE’s second-generation KDGS-2 stabilization system and powered by the KT 3.0 processor, the APC 18x50 corrects even the slightest hand movements in real-time, offering a rock-steady viewing experience without the need for a tripod. The MHR Advance+ coating system enhances light transmission to an impressive 86%, ensuring bright and vivid images even in low-light environments.
The integrated Li-Ion battery provides up to 30 hours of continuous use and recharges easily via USB-C. With Angle Power Control (APC), the unit intelligently powers down when laid flat and instantly reactivates when picked up—extending battery life during extended outings.
Fully IPX7 waterproof and nitrogen-purged, the APC 18x50 ED Li-Ion is built to handle extreme weather conditions, while its rugged yet lightweight design ensures comfort and portability in the field. The binoculars also feature a tripod thread, hand strap, and a low battery indicator for added convenience and reliability.
Whether you're scanning distant landscapes or tracking fast-moving subjects, the APC Stabilized 18x50 ED Li-Ion offers cutting-edge stabilization and optics for serious users who won't compromise on performance.
