Threat Sensor

"A reflected energy device [which] tunnels through walls to highlight obscured enemies."

― Equipment menu description

Multiplayer
The Threat Sensor is a device in Doom (2016) that, when thrown, attaches to a surface and highlights enemies within its radius. Both allied and enemy players can hear it beep when they are nearby, and it can be destroyed with weapons fire. It is a multiplayer-only equipment item, and recharges after use. It is unknown why it takes so long to unlock (level 38) when it is basically just a weaker Threat Pulse. Thankfully, it does have at least one upside, which is that it can scan an area for far longer than Threat Pulse.

Trivia
The image taken of the Threat Sensor says that its name is the 'UAC Threat Detector;.
