Description
The ATERA H10x21, weighing just 358 grams, is one of the lightest binoculars with image stabilizer. Its powerful vibration canceller ensures a rock - steady field of view, even when held freehand. At 10x magnification, you can observe objects in stunning detail, like reading small print or examining bird feathers. It's also great for astronomical star gazing.
Hand tremors often blur sharp views, especially at high magnification. The ATERA H10x21 has a 2 - axis gimbal - mounted image stabilization mechanism. With a strong vibration correction angle of ± 3 degrees (up, down, left and right), it provides a stable view even at 10x magnification. Micro - vibrations are eliminated, revealing the tiniest details.
Powered by two standard AAA batteries, which are easily available anywhere. Enjoy up to 12 hours of operation without worrying about battery drain. An automatic power - off function after 5 minutes prevents unnecessary battery loss.
All lens surfaces are fully multi - coated and anti - reflection coated, and the prisms have an additional phase coating. This boosts light transmission and brightness, reducing stray light and light loss for a crystal - clear, high - contrast image. Its gently rounded shape fits the hand, a single - finger - touch focus ring, simple design, and a battery compartment away from the operating area make it user - friendly. The integrated battery cover protects against loss.
The ATERA comes with a comfortable carrying strap and a protective transport bag.
