A modern hunter stands inconceivably far from our prehistoric ancestor with a stone spear that was his main weapon. What a nightmare a moonless night in African savannah with numerous predators around would seem to defenceless tribal people ages ago! Technologies started emerging when somebody guessed how to tie a stone to a cane and bring light to the desert with a torch. And this is how, step by step, we, as mankind, eventually came to long-range sniper rifles equipped with thermal scopes.
At the same time, large possibilities mean large responsibilities. Thermal vision allows us to see the warmth of a live creature and insensate objects, turn darkness into light, night into day. For many, this situation looks scary. More and more often we hear calls to limit or even ban the technologies that make hunting more effective.
I do not share these concerns. If new technologies deliver a chance to discern a beast better, define it correctly and shoot it down with a single shot, this is only for good for nature. Our history knows examples of how the whole animal populations became extinct without a hint of any advanced technology. The torture and suffering that humans exposed to animals with grandfather’s weapons were enormous. Nowadays the much more sophisticated technologies are ubiquitous and used for various purposes like science, regulation of animal population and fighting against poachers.
Forgive my pathos. Like every decent hunter, who kill animals occasionally, I unwittingly puzzle myself sometimes, if I have made everything to not bring harm to the environment and leave our world better than it is now for our children and grandchildren. Dedal-NV makes available the most modern and effective technologies for us. We must use them responsibly justifying our earthly mission and species name: HOMO SAPIENS.

About Thermal Vision
Every object having a temperature above the absolute zero (- 273.2°C) emits electromagnetic waves in the infrared range. According to the laws of physics, the intensity of thermal emission is proportional to the fourth power of the temperature of the heated object. Consequently, the detection ability of heated objects’ emission by receivers sensitive in the infrared range depends mainly on the temperature of the object and its surrounding background. It does not depend practically on the illumination level in the visible range.
Infrared emission occupies an extensive part of the spectrum, which is commonly divided into several ranges.
A commonly accepted division of infrared emission into ranges is connected with both sensitivity ranges of existing receivers and atmospheric transparency windows.
A night vision device works in visible and close infrared ranges (wavelengths from 0.4 to 1.0 microns) thanks to the detection of natural and artificial light reflected from observed objects.
Modern compact thermal vision devices work in the range from 8 to 14 microns that corresponds to one of several atmospheric transparency windows. The action principle of thermal vision devices is based on the ability of certain materials to register object images formed by infrared emissions and transform them into electrical signals. Received electrical signals that are determined by the thermal scene of observed terrain are transferred onto the built-in microdisplay after amplification and software processing. The display transforms these signals into a picture of the observed objects that is visible to the human eye.
In total darkness and adverse environmental conditions (smoke, fog, rain. snow), when night vision riflescope become helpless, only a thermal imaging riflescope can save the situation. The thermal imaging device always detects and identifies a heat signature target.
Thermal Imaging Binoculars produced by Dedal-NV are designated for extended and comfort observation in the night time and during inclement weather conditions (smoke, fog, rain, snow), when daytime or night vision optics is of no use, Thermal imaging devices detect and identify a heat signature target practically momentarily.
In night time and bad weather conditions (fog, rain, snow) light-gathering power of even the best quality daytime riflescope becomes insufficient for successful aiming. You would need a special device called a Clip-on Attachment, which is compatible with your daytime riflescope and is mounted in front of it. As of today, the most effective technical solution in this technology zone is the Thermal Imaging Clip-on Attachment. Our Clip-ons can also be used as autonomous observation devices or together with daytime binoculars or a spotter.
