## Long description

The Technaxx TX-257 Black 4x Magnification CMOS Sensor binocular combines optical viewing with digital capture in a compact, portable body. With 4x magnification and a 2.5 cm objective diameter, the unit provides closer views of subjects while the integrated CMOS sensor enables photo and video recording. Captured images are saved in JPG format and video files in AVI format to a MicroSD card (supported up to 32 GB). The binocular's dimensions—124 mm width, 140 mm depth and 60 mm height—make it suitable for outdoor activities where space and weight are limited.

Common image and video formats (JPG for photos and AVI for videos) ensure compatibility with standard image viewers and video players. The compact dimensions and lightweight form factor make the binocular easy to carry and handle during trips, hikes, or casual outdoor use.
