Nitehog Viper 35 and 50 thermal clip-on
Nitehog is a well-known player in the thermal imaging device market. It originated in Bulgaria and is now based in Germany, where its products are assembled.
The Viper range is the smallest, lightest and most compact thermal imaging device in its class. Designed as a clip-on, it easily attaches to any riflescope, allowing for both day and night shooting without having to remove your day scope.
