  1. It permits an enlarged field of view of 26 metres at a range of 100 metres, with a focal length of 25 mm.
  2. It gives a complete overview in total darkness, either from a high seat or the bait site.
  3. Users will be able to detect all heat sources, even at close range.
  4. The camera works silently and unobtrusively.
  5. Easily identifiable controls allow swift, accurate use
  6. Both left-and right-handed stalkers will find operation uncomplicated, even wearing gloves and in the dark
  7. The camera has been designed for easy-one handed operation
  8. Sensor, electronics, screen and eyepiece work seamlessly together
  9. Switching from maximum overview to higher magnification is straightforward using the digital zoom with increments of 0.5x
  10. The fine, gradual zoom picks out even small details
  11. The new DTI 3/25 and the popular DTI 3/35 thermal imaging cameras can be connected to the ZEISS Hunting app to manage and share photos, videos and livestream hunting.
  12. Latest firmware is installed, unlocking features such as improved focusing with contrast enhancement and a focus frame in picture-in-picture mode.
  13. The LED screen can be switched off manually to assist camouflage.
  14. The Contrast Boost feature increases contrast between light and dark at the edges, countering conditions of fog and high humidity.
  15. The high resolution display gives images with exact detail enabling reliable target identification, even in total darkness.
