Night vision devices are mounted on scopes to enable precise shooting even in darkness. Unlike front-mounted devices, they are not attached to the objective lens, i.e., in front of the scope, but to the eyepiece, i.e., behind the scope.
It is often recommended to use night vision devices together with an infrared illuminator (as shown in the title image). Warning: Currently, the use of an IR illuminator is only permitted in Bavaria!
The most popular night vision devices are from PARD, e.g., the PARD NV007A. This is a dual-use device. It can be used both as a handheld device and in conjunction with the scope. However, the IR illuminator is permanently built into the device, which makes a significant difference under weapon law. According to weapon law, only devices that are not permanently connected to an IR illuminator may be mounted on the weapon. (More on this below)
The device has low magnification - ideal for mounting on the scope, suboptimal for handheld operation because a higher magnification is advantageous for safe aiming. The device can be connected via Wi-Fi with an app, and the photos and videos taken and stored with the device can be easily accessed and viewed.
The mounting to the scope is done via a "clamping ring," which is firmly attached to the scope and remains there. The night vision device is connected to the scope via a bayonet mount - the installation is incredibly quick.
The advantage of the device, which fits any scope, is that it costs only about 400 euros.
Night vision and front-mounted devices have different advantages and disadvantages. The most important advantage of night vision devices is that they represent a significantly cheaper solution than front-mounted devices. Among these, thermal front-mounted devices, which can be used regardless of the prevailing light conditions, are the most expensive and perhaps the best solution. Night vision devices have the disadvantage of extending the weapon backward, i.e., towards the shooter, which means that shooting must be done in an unfamiliar body position - because the eye is significantly further away from the weapon due to the extended optics. However, the fact that the night vision device is behind the optics also has the advantage that it does not need to be zeroed, unlike front-mounted devices.
Night vision devices, like front-mounted devices, are legally permitted for hunting wild boar under the Third Weapons Amendment Act. However, this must also be legally permitted for hunting, and hunting law is state law - different regulations apply in each federal state. Currently, the following regulations apply to the states.
