Used or brand-new image intensifier tube

A lot of suppliers fit their „new“ night vision devices with second- hand image intensifier tubes from military stocks. At first glance their price seems to be reasonable, but there are several crucial disadvantages:.
- The rate of failure is about 37% within the first three years. As the image intensifier tube ist the most expensive component of a night vision device the cost of repair is as high as the price for a new one..
- According to their age and use, second-hand tubes often reach only about 50% of the performance of new tubes.

Shock- and flash resistant

Night vision devices need to be shock resistant as well as flash resistant when it comes to hunting at night. Practice has shown that non-resistant devices fail to withstand the considerable stress that is caused by shock and flashes of light. That is why we recommend you to make sure you are provided with a certificate stating shock- and flash resistance. Otherwise any claim for defects liability or maintenance guarantee will be rejected . We guarantee that Jahnke DJ-8 devices are shock- and flash resistant with all calibers.

Good optics are important

The term „optics“ means the lens and the ocular. Only if both are of the highest quality you will get a perfect image in the end, as you sure know from your scope/telescopic sight. Conversely, even the best image intensifier tubes cannot reach their full potential with poor optics. The lenses used in our DJ-8 are designed for maximum infrared light penetrability and coated accordingly. The result is a clear, high-contrast image as well as an optimal ability to be combined with IR lamps.

How reliable are performance details

Figures speak for themselves, as the saying goes. Yet in the case of night vision devices, the matter is not so simple.Unfortunately, it can be seen time and time again that many suppliers work with estimated values or even present you with completely made-up figures. Yet even correct values do not always provide you with the information you require. For example, an image intensifier tube with high light amplification can produce a poor result if the signal-to-noise ratio is too low.

Our guarantee conditons

An incresing number of dealers grant no guarantee, just the warranty prescribed by law. For you, this means in the event of damage that occurs after more than six months, you as a cusomer are required to prove that there was a defect from the outset. That can be difficult. That is why we offer you a genuine guarantee- and this is for up to 48 months. During this time you are legally entitled to have your device repaired without ifs or buts. However, it is highly unlikely that this will be necessary.

As you can see, choosing the right night vision device is not easy. Yet, there is a very easy way to find the perfect night vision device: Test the devices under real conditions. You will realize that one thing is more convincing than figures: your personal impression. .
