Stalcraft Wiki: Beluga Short Range Detector

In-game description (EXBO)

First short range detector equipped with a screen that visualizes the signal's location. Like other devices working with the detection of anomalous signals, it uses a component based on No. 137-IA. Despite its apparent simplicity, the task of integrating the component with the visualization system proved quite challenging even for the engineers at Research Institute 7. However, this innovation was warmly received not only by stalkers but also by the institute's operatives.
