Its sophisticated image processing software and two easy-to-change image modes ensure a natural image that makes even the smallest details incredibly clear. The high-contrast OLED display impresses with its wide brightness range. Enjoy highest precision in pocket format – for comfortable day and night observations!


Easily manageable main menu, zoom and other functions via a scroll wheel located right in the center of the device. Customize the menu navigation with standard, custom and basic modes as well as the quick menu according to your needs. This allows you to quickly access frequently used functions.
