Technical aids are also becoming increasingly popular in the field of hunting. These include night vision devices and night vision cameras. As the name suggests, these are primarily intended to facilitate hunting at night by providing the hunter with an adequate view even in the poorest light conditions. Since according to § 19 paragraph 1 number 4 of the Federal Hunting Law in the Federal Republic of Germany no cloven-hoofed game except wild boar may be hunted at night, sows in particular are to be hunted with the help of such devices. A good view of the wild boar and the associated possibility of being able to address them more precisely is particularly important at the times of leading sows. Especially small freshlings, which cannot be seen as well through binoculars or telescopic sights as larger pieces, can be detected by the night vision device.

Furthermore, it is imperative that § 2 para. 3 of the Weapons Act i. In conjunction with Appendix 1, Subsection 1, Section 4.3 (definition) and Appendix 2, Section 1.2.4.2 and Section 19, Paragraph 5a of the Federal Hunting Act, according to which it is not permitted to use a device that is suitable for night vision (night vision or thermal imaging optics) in conjunction with a weapon, for example through adapters, mounts or the like for targeted shooting of game. Accordingly, the use of so-called night vision sights is still prohibited.

Thermal imaging technology is also being used more and more frequently in the field of hunting. This has the advantage over night vision technology in that the display of the heat gradation makes game stand out from its surroundings, making it easier and faster to detect. With most night vision devices, it definitely takes a little practice and experience to be able to use them efficiently. Initially, one must first become familiar with the technology and its peculiarities in displaying the area being viewed. This is especially true for those night vision devices and cameras that have integrated infrared illuminators in addition to the usual residual light amplifier. In terms of price, however, night vision technology is in most cases considerably less expensive than thermal imaging technology. However, both have one common disadvantage: neither the commercially available thermal technology nor the night vision technology allows one to detect a piece of game hidden by another object, e.g. a tree.

Nevertheless, the market for technical aids of this type is growing rapidly, as hunters are eager to use them, especially because of the security they provide when approaching game.
