The Object Scanner is a tool used to scan objects of interest within a 250-meter radius. Its 'upgrades' are unlocked via M.A.M. research, which allows for more objects to be scanned for.
With the Object Scanner equipped, to cycle through scan-able objects or hold down to open up the radial menu. After selecting a scan target, the light atop the scanner will glow and blink the same color as the selected object once one is detected. When looking and moving in the general direction of the detected target, the detection bar on its screen will rise. At the same time, the white noise sound produced by Object Scanner will fade and be replaced by a beeping that gets progressively more rapid the closer the object is.
