Question? Can Take my Thermal/Night Vision to Canada on a hunting trip?

No Exports.No Exceptions. This includes taking Night Vision of a international hunting trip
Export of Night Vision Equipment or related accessories (such as manuals, parts, Thermal Imaging, lasers, ect) is strictly regulated by the US Department of State Office of Defense Trade Controls, in accordance with the guidelines of the International Traffic in Arms Regulations (ITAR)Title 22, Code of Federal Regulations Part 120-130 . It is a major crime to ship or carry night vision devices outside the borders of the United States, punishable by fines and prison sentences. Ignorance of these regulations will not hold up in court. By purchasing night vision equipment from Night Hunter, you attest that you are a lawful United States citizen and will follow all local, state, and federal laws related to these products. You agree to not attempt to export or carry this night vision equipment outside the borders of the United States (this includes travel to Canada and Mexico). Also, it illegal to allow a non-US Citizen to look through US Gen3 Night Vision Devices, even on US soil. Law enforcement personnel are NOT exempt from these laws. For further information contact the Office of Defense Trade Control @ (202) 663 2700.


Question: Why can’t civilians buy High Power IR Lasers? 
Answer: All IR Lasers are controlled by the U.S. Food & Drug Administration (FDA).  IR Lasers can only be viewed through Image Intensifier Night Vision technology and are invisible to the naked eye. Because of this, and the high power in which they operate, IR lasers can cause significant damage to eyes if exposed. Human and animal eyes have a natural aversion to bright light. When exposed, the natural reaction is to shut or avert the eyes. Because IR lasers are invisible to naked eyes, there is no reflexive response to look away or shut them. This means exposure can take place without the victim even knowing it, causing serious damage or permanent blindness. So, it is clear why the sale of these devices is restricted. http://www.fda.gov/

Question: Do you sell used / refurbished equipment? 
Yes, Generation 3 Tube life is on average 10,000 hours. Generation 3 will provide many years of service. 

Question:What is the main difference between Generation 2 and Generation 3 night vision? 
The primary difference between the two generations is the photocathode. Generation 2 uses a multi alkalisphotocathode while Generation 3 uses Gallium Arsenide. Which provides a significant increase in photoresponse and tube life. Other differences in performance will be image tube resolution, tube gain and signal to noise ratio. Therefore Generation 3 offers greater clarity but is generally more expensive than Generation 2. Generation 2 night vision works well in most situations while Generation 3 will achieve high performance in all conditions. Can Generation 1 be useful? Yes, Generation 1 can be useful in most nighttime situations. Newer Generation 1 devices do offer increased performance from there older predecessors. Generation 1 units typically use an S-20 photocathode and electrostatic inversion to achieve gain. They can offer substantial resolution toward the center of the image tube, while the edges may be blurred. Generation 1 devices are usually inexpensive and can be a good start for the night vision enthusiast. 

Question: Why is night vision green? 
Night Vision is deliberately green in color as shading levels in green are the easiest for the human eye to distinguish.
