Thermal Visor

The Thermal Visor is a visor in Metroid Prime, and it is the only Visor that is exclusive to Metroid Prime. It is acquired in the Research Core in the Phendrana Drifts.

The Thermal Visor uses thermography, allowing Samus Aran to locate enemies or objects by their heat signatures. It can be used to see Shadow Pirates and is also useful in dark places, extreme cold, and in poor weather conditions, like those in Phendrana Drifts; though it functions poorly in superheated areas, such as the Magmoor Caverns.

Other uses for the Thermal Visor include locating power conduits to energize with the Wave Beam, allowing Samus to open unenergized doors, locating Thardus' weak spot, and locating Metroid Prime when it becomes invisible to the Combat Visor and X-Ray Visor.
