D-336 GT Distinctive features

The Dedal-336 GT is our newest and powerful multifunctional thermal vision device intended for supervision over objects having thermal radiation under any conditions of illumination (day, night, twilight), including under any weather conditions (rain, fog, snowfall, etc.).

The principle of the device operation is based on transformation of infrared radiation from objects of supervision and its representation in a look, convenient for perception. Also there is a possibility of changing of the color schemes of the image processing – “the hot black”, “the hot white”, “sepia”, “the hot red”, you can choose between seven different varieties!

Dedal-336 GT Multi-functionality: the sight can be used as a Thermal vision clip-on attachment for a daytime scope and as a Thermal vision observation device.




  • Installation in front of a daytime scope does not affect the latter’s zeroing.
  • All features of the daytime scope remain the same
  • Modern high quality infrared sensor made by FLIR Systems Inc. (USA)
  • Spectral sensitivity in 8-14 microns range
  • Internal focusing system that perfectly keeps the point of aim
  •  Automatic calibration system of the shuttered sensor
  •  Special germanium fast optics
  • Large diameter of exit pupil
  • High image quality through the entire field of view
  • Easy, intuitive operability
  • Hermetically sealed and shockproof
  •  Compact and lightweight
  • Low power consumption
  • 2 years warranty
