More and more hunters today include thermal imaging weapon sights to their standard hunting equipment set.
Spread of thermal sight among hunting professionals has been conditioned by several factors. Most hunted animals are active in the evening or in the night when they start looking for food. Some years ago, professionals used to buy riflescopes with large aperture objective lenses to hunt in the evening in low light conditions or night vision scopes to hunt in the night. Now, the use of night vision or large aperture optics can be limited by the amount of remaining light and weather factors such as fog rain and snow.
