See Every Emotion. The Lightest 10× Model in the ATERA II Series
The lightest model in the ATERA II image-stabilized binocular series, the H10×21 combines exceptional portability with powerful performance. At live concerts and outdoor events, it brings you close enough to see even the performers' facial expressions. Two selectable image stabilization modes provide powerful shake compensation, delivering a remarkably steady view even when the binoculars are hand-held.
Vixen Binoculars ATERA II H10x21 (Greige) Description
-
Built-in vibration canceller keeps your view steady
One of the greatest advantages of binoculars is their portability, allowing you to observe virtually anywhere. However, image shake can make it difficult to keep your object in view, especially at higher magnifications.
The ATERA II H10×21 features a built-in image stabilization system based on a two-axis gimbal control mechanism. It effectively compensates for image movement by up to ±2° in all directions, providing a remarkably stable field of view when hand-held.
By suppressing even the slightest hand tremors, the ATERA II lets you clearly see fine details, such as the glint in a bird's eye or the intricate patterns of its plumage. For astronomical observation, image stabilization also makes it easier to detect faint stars that can be difficult to see with conventional binoculars, allowing you to enjoy a sharper and more comfortable viewing experience. -
Two image stabilization modes for different viewing situations
The binoculars feature two selectable image stabilization modes, allowing you to choose the one that best suits your viewing situation.
V1 Mode: Compensates for small, rapid vibrations. Ideal for tracking moving objects.
V2 Mode: Compensates for larger, slower movements. Ideal for observing stationary objects. -
Ultra-Lightweight Design for Easy One-Handed Handling
Surprisingly lightweight at just 358 g for image-stabilized binoculars, the ATERA II H10×21 is engineered for comfortable one-handed handling. Its lightweight construction helps reduce fatigue, allowing you to enjoy extended viewing sessions in comfort.
-
30 hours of operation on two AAA batteries
Powered by two readily available AAA batteries, the ATERA II H10x21 delivers up to 30 hours of continuous operation. This long battery life lets you enjoy outdoor observation, concerts, sporting events, and other activities without worrying about frequent battery replacement. (Battery life is based on alkaline batteries at an ambient temperature of 20°C (68°F).)
To help conserve battery power, the binoculars are equipped with an automatic power-off function that turns the power off after 90 minutes. -
Three advanced optical coatings for a brighter, clearer view
All lens surfaces are fully multi-coated with anti-reflection coatings to maximize light transmission. The prisms are phase-coated to minimize phase shift, improving contrast and resolution. In addition, high-reflectivity coatings on prisms further enhance light transmission. Together, these three advanced optical coatings minimize stray light and light loss, delivering an exceptionally bright, high-contrast, and crystal-clear view.
-
Comfortable Grip and Intuitive Operation
The smoothly rounded body fits comfortably in your hands, making it easy to hold even for users with smaller hands. The focus wheel turns smoothly with just one finger and a light touch, allowing effortless, precise focusing. Designed for comfortable use by both right- and left-handed users, the binoculars feature a universal ergonomic design. To enhance handling comfort, the battery compartment has been positioned away from the grip area, so it does not interfere with your fingers while holding the binoculars. To help prevent parts from being misplaced in dark environments such as concert venues, the battery cover is tethered to the battery compartment, creating an integrated, user-friendly design.
-
Removable, Washable Silicone Eyecups
The binoculars come with removable silicone eyecups that can be attached or removed to suit your preferences. The eyecups can be easily washed with water and a mild detergent to remove makeup, skin oils, and other residue, helping keep them clean and hygienic. Made of silicone, the eyecups are less likely to attract dirt and are more resistant to aging than conventional rubber eyecups. Silicone is also a skin-friendly material that is generally considered hypoallergenic, making the eyecups comfortable and suitable for a wide range of users.
-
Clean, Stylish Design
Despite their advanced image stabilization mechanism, the binoculars have a clean, smoothly contoured body that feels comfortable in the hand. The refined charcoal-gray finish gives them a sleek, sophisticated appearance.
-
Drawstring Carrying Pouch
A mini tote-style carrying pouch is included. Featuring a drawstring closure, it neatly stores the binoculars together with the neck strap, keeping everything organized.
