KITE 10x30 APC Stabilized Binoculars bring you the latest technology in binocular image stabilization—correcting image stability by 3° for perfectly stable images, not only from a trembling hand, but even from a driving car or a boat in strong seas. This compact, lightweight instrument is powered by two AA batteries, the most common battery size worldwide, with runtime of up to 36 hours. It is ergonomically shaped and features a 1.6" long focus wheel that can be easily operated with 3 fingers.
The APC (angle power control) function detects positioning. When the instrument comes into vertical position, hanging from your neck or standing on a surface, it goes to sleep. From the second it comes to a more horizontal position, when viewing, the stabilization kicks in. No switching of buttons, no accidental battery drain. A timer function makes sure it switches off completely after 90 minutes, no matter the position, and a low battery indicator will warn you when new batteries are needed.
